Kor's Door climbs the clean buttress just left of Stettner's Ledges in 3-5 pitches of exquisite crack climbing on perfect alpine rock. This is a great route at the 5.9 grade, well-protected, secure, and interesting. The rock quality is flawless from bottom to top.

From the broad basin at Mill's Glacier head to the broken Class 4 ledge systems right of Lamb's Slide. Wear a helmet, and if crossing below The Notch area move quickly since rocks come whizzing by here all the time. You will most likely have to cross some snow and/or ice to reach the toe of the buttress. Once on the broken buttress, you are shielded from rockfall. Scramble up the buttress to a perfect grassy ledge below the obvious rectangular inset with a large flake poised at it's lower left. The perfect diagonal crack to your right is Malander's Passage.

Pitch 1. Move up and right, heading for the crack and corner system on the right side of the inset. You will pass the large detached flake on your left. Climb through a small roof at a handcrack (5.9-), and belay 30 or so feet higher at a small stance.

Pitch 2. Continue up the crack past several fixed pins through a second small roof. There is an optional belay on the left. With a 60m rope you can continue up and right into a thin right-facing corner to a ledge and belay. You can even move to a higher ledge, and the end of the steep climbing, in a single 60m pitch.

Pitch 3. Many ways to exit. Move into the large. right-facing corners on the right (you are now on Stettner's), and continue to Broadway with a bit of simul-climbing.

Head right on Broadway, and cross below the Notch to hit Kiener's and the route to the summit. If you don't want to go up and over Long's, descend Lamb's Slide (ice axe/crampons required); rappel Alexander's Chimney; or rappel Crack of Delight below the Diamond (2 ropes, ice axe/crampons may be necessary to get across snow below Obelisk - this can be sketchy with loose rock so not recommended).

If you want to avoid the simul-climbing and climb shorter pitches, no problem, there are plenty of places to stop and belay. This would result in about 5 pitches of climbing to reach Broadway.

One strategy for this climb is to go light, one rope, a light rack, and each climber carry a light pack. Once on Broadway, put on your approach shoes and pack away the gear (although you may want to keep the rope out for the first 150 feet of Kiener's) and shoot for the top.


1 set wires to 3" cam. Slings. There are a number of fixed pins on the route.

Does anyone know the current conditions on Broadway getting from the top of Kor's Door over to the Crack of Delight rappel route? Any snow or ice to deal with? The area below Window Direct and Hypotenuse looks like it might be a problem. Jul 20, 2004

That little hanging snowfield below the Window and The Obelisk was pretty big as of Thursday 7/15.might suck getting down that. The rest of Broadway from there is fine, almost completly snowfree. Don't know about he far left side above the East Face. Jul 20, 2004

A superb and aesthetic climb, marred only by a long approach and problematic descent.

We stashed extra gear at the foot of Lamb's Slide, and continued up in rock shoes, leaving our approach shoes behind. This was probably a mistake, making the initial snow crossing more difficult. We brought ice axes, and I used mine on this initial snow section. My partner did not use his axe, but kicked toe-holds with his rock shoes. Once we got to the rock, we had a half-hour 3rd- and 4th-class scramble up to the start of the route. See the photos for details on the approach and climbing route.

From Long's Peak trailhead to the start of the climb took us 5.5 hours, with about an hour spent at several rest breaks and gearing up for the climb. A faster party could shave an hour or two off our time.

The climbing on the first three pitches was excellent: solid rock, good moves, continuous difficulty at the 5.7-5.8 level, with two brief cruxes that felt no more than 5.9-, even carrying a pack. Our rack was a set of wired nuts, 5 tricams, a set of Aliens (black to red), and a set of Camalots from #.5 to #3. An extra #2 Camalot came in handy several times. We also brought extra smaller cams but did not use them. As Steve mentions, there are several fixed pins on the route. We climbed on double 8.5mm x 60m ropes.

We split the pitches up a bit differently than Steve did:

1. Up a right-angling ramp to the right side of the inset, up the corner and turn the roof on the right. Belay at a small stance 30' above the roof (5.9-, 160').

2. Up a crack to a roof, turn the roof on the right, and continue up to a good ledge on the left with a fixed pin. (5.9-, 70').

3. Up a crack to a thin right-facing corner. Climb the corner, then work left and up to the big ledge at the end of the Alexander's traverse (5.8, 80'). This pitch looks hard and thin from below, but the pro is good and the climbing is moderate.

4. Up and right, heading for the right-facing corners of the Hornsby Direct. Follow the corner mentioned in the Stettner's Ledges write-up. Continue up the corner to the end of the steep climbing and belay at a small stance (5.8, 190').

5. Up a right-facing corner to a roof, then traverse right to a grassy ledge. Continue right and up to Broadway. (5.5, 190'). We ran the rope out on this pitch, since we were headed to the Crack of Delight rappels. If you're heading to Lambs Slide or the Alexander's Direct rappels (see Stettner's Ledges), you would want to finish farther left than we did.

Time on the route: 4.5 hours.

Now for the problematic descent. We decided to do the Crack of Delight rappels, which turned out to be a big mistake. It would have been better to continue on Kiener's and descend the north face. It also would have been better to do the Alexander's Direct rappels or descend Lamb's Slide.

Once on Broadway, we unroped and traversed over to the Crack of Delight rappels. Getting to the Notch Couloir was fairly easy, but as we continued north, conditions got progressively worse. The difficulties culminated when we got to the big snowfield below the Windows and Obelisk routes. We carefully downclimbed loose, wet scree beside the snowfield. Near the bottom of the snowfield, we had to downclimb on snow for about 20 feet. This wasn't too difficult since the snow was fairly soft, but I was glad to have an ice axe. There was an icy patch at the bottom that required care.

The next section, just below the snowfield, was wet, loose and dangerous. My partner sololed it; a foothold gave way and he was able to hold onto a wet rock to prevent a fatal slip. He got to the rock wall, set up an anchor and belayed me across. See the photo for details. We also belayed the exposed 50' rock traverse from here over to the Casual Route area. The traverse was easy, but a slip would have been fatal. Doing the traverse in wet rock shoes didn't inspire confidence.

We finally got to the Crack of Delight rappels 1.5 hours after starting the traverse of Broadway. The rappels were excellent: four solid bolt anchors. Here are the details:

1. From the bivy cave just left of the start of the Casual Route, walk down and north on a grassy ledge to the first anchor. Rappel 100' and angle to the rappeller's right to get to the next anchor.

2. Rappel 150' straight down. Pull the rope to the right to avoid the chimney on the left.

3. Rappel 150' down a slab, and angle to the rappeller's right to a stance at the edge of a gully. I missed the anchors when I went down, and had to climb up the gully for 30' to get to the anchors.

4. Rappel 100' straight down to a ledge just above Mills Glacier.

Time on the Crack of Delight rappels: 45 minutes.

From here, a fun glissade down Mills Glacier and some talus hopping got us back to our stashed gear at the foot of Lambs Slide.

The hike back to the trailhead took 2 hours, 20 minutes from here, going at a much faster pace than we hiked in.

A great route; well worth doing. Just be sure you have your descent plan figured out before you start up. Aug 2, 2004

What a stellar route, absolutely beautiful. Clean, great rock, solid. Ron's excellent description above says it all, I can only agree. I thought the route to be an easy 5.9, maybe even a 5.8+. We chose the Alexander's Chimney descent, a very viable option to consider. Check out the description under that route. Aug 9, 2004

With a 60-meter rope it's only 2 leads up to the Traverse on Alexander's chimney. One can do the traverse on Alexander's in reverse & rap from below the big chockstone to a good rap station on the west wall of the chimney. You need two ropes for this or you need to be prepared to fix an old rap station 1/2 down the rap from below the chockstone. It is then one short rap to the ledge system Kor's Door starts on. If the chimney was dry it would be an easy down climb, but it's always wet in there. Real straight forward climbing on Kor's Door. If you know how to climb crack, it is not 5.9. More like 5.8 in my opinion, but maybe the fact that you can put in pro anywhere along the route took the bite out of it. Aug 16, 2004

Did this route and have some things to add: Maybe it was me, but the crux was very wet and felt right on or maybe 9+ (probably because it was so wet). Secondly, we rapped Alexander's, and we had a near epic for several hours after trying the recommended double rope rappels and being unable to pull our ropes from one of the chockstone rappel anchors. The chimney soaked us and our skinny ropes, which I'm guessing is why we could not pull our ropes (due to our rope being soaked and impossible to pull). I ended up have to prussik/climb back up the chimney to get the rope, and then rap from a crappy intermediate station. I added a biner and quickdraw which made it a little better. It was kind of terrifying, and the worst rap I've ever done. So, if you do this rap, a single 70m rope (which we had, with our skinny tag line) is you best option and using the intermediate rap station. Other than that, great route! Single set cams from black Alien to #3. Doubles from .5-#2 BD to sew it up. Jul 28, 2006

Great Route. did it the second time! I would suggest using one single 60 meter rope to get up and down this via Alexander's Chimney. No rope drag and much faster this way. Time is everything up here. Aug 3, 2007

Kor's Door is a spectacular route at the 5.9 grade. Don't let any of these MP sandbaggers convince you it's 9minus! I felt this route - and granted I whipped on it a year ago - is solid 5.9 through both roofs with attention-grabbing climbing in between. My partner and I pitched it out thusly, allowing for a non-5.9 leader and a 5.9 leader to swap pitches:

P1: Climb up the low angled corner, past a piton and around the flake to belay at the base of the left-facing corner system. 5.6, 45 ft.

P2: Climb the left-facing corner through the roof (5.9), and continue up the face/thin cracks above to a right facing corner. Continue through the 2nd roof at 5.9 with several fixed pins along the way, moving slightly left after clearing the roof and up to a nice belay ledge (w/ fixed pin). 5.9, ~200 ft.

P3: Move up broken cracks immediately above the belay to a right facing corner. Ascend this to a decent ledge and stretch the rope out up blocky 5.5 terrain to a suitable ledge at the base of a right-facing flake system. There's an old bolt at the ledge that could be utilized in an anchor if needed, and a piton in the flakes/cracks just above. 5.8, 170 ft.

P4: Hornsby Direct. Move up the easy flake, clipping the pin along the way, reaching the ledge-y top of the flake. Step right and ascend parallel right-facing dihedrals (right of a leaning RF dihedral) moving between them as difficulty and protection demand. Belay from cracks above a boulder on Broadway. 5.8, Felt long - 170 ft? Could be less.

Finishing via Hornsby Direct was, for us, necessitated by our position on the wall too far right to move easily toward the Yellow Bowl at the end of P3. However, taking this line of ascent makes, arguably for more of a rock climb - Kor's Door is short, and instead of a couple (or one long) 5.9 pitches amidst easier climbing, the HD finish stretches out the route and keeps it a bit more sustained, and fun, than scurrying over loose-ish easy stuff to the Yellow Bowl.

DESCENT BETA: We moved left (south) along Broadway to the top of Alexander's Chimney, which can be rappeled with a 70m rope in 4 raps.

Rap 1: From just below Broadway (2 pin, 1 nut anchor with slings) rappel 100ish feet to a slung horn/nut anchor.
Rap 2: Another 100+ feet from the large horn down the face, past a station, and behind a large, slung chockstone to a ledge.
Rap 3: From a small slung chockstone/nut anchor at the ledge, rappel over the edge and down the chimney. At a stance about ~118 ft. down, carefully slide off the end your ropes (!!!) and clip some tat on a piton/I-beam-shaped-chock anchor on the north (climber's right) wall.
Rap 4: Keep rappelling down the chimney another 115 ft. to ledge-y terrain. Stop near the end of the rope, clipping into a down-ward driven pin in a ledge at head height to pull and coil up your rope.

From here, descend right (north) down 4th class ledges, encountering a couple 5.0-5.2 steps along the way back to the bottom of Lamb's Slide. This line of descent climbs right below the Door, and so is a reasonable descent for those leaving gear at the bottom of the climb. These rappels could be completed easily with double 50s or 60s, and could be managed with a single 60m rope - there are many intermediate stations and fixed pins (keep your eyes open) along the chimney that could be utilized for making 100' rappels. If rappelling with one 60, bring some extra slings, rap rings, and maybe extra nuts to beef up some of manky stations along the chimney.

This rappel route is undoubtedly quicker than traversing Broadway all the way to the Crack of Delight, especially if you leave gear at the base of the climb. Be warned, though, the Chimney is very wet, and your rope will probably be sopping (mine was) no matter how hard you try to keep it out of the small waterfall. This line of ascent/descent took my partner and I less than 5.5 hours, and we weren't moving particularly fast. Aug 14, 2009

My partner and I were able to do this line and Hornsby Direct to Broadway in three pitches with 60m ropes.
End pitch one just over the first roof, as described.
Stretch pitch two past the shallow 5.8 dihedral and go up and left on ledges as far as possible.
Third pitch requires 30 or 40 feet of simul-climbing. The bottom guy is on easy 5.4 ledges and the leader is on maybe 5.8 face climbing. Sep 7, 2011
No need for complicated descent beta. Best exit strategy: One rope/one pack, Kiener's, Summit, N. Face, Camel, retrieve second pack stashed at bivy sites, car, beer. Aug 13, 2013
Seemed like 5.8+ when we did the likely FFA in 1974. But a nice route on great rock! Aug 1, 2014

Just another pitch breakdown and gear beta:

Approach: from the Mill's Glacier scramble, or short pitch, go up the loose, broken ledges left towards the obvious start of the route. This is all-in-all about 300' of low-5th class terrain.

P1: 180' 5.9. From the left side of the 'Door' work right into the corner with some cool stemming to reach the roof. Pull the awkward roof and belay at a stance.

P2: 75' 5.9. Go up the broken cracks to another roof. Stem up through the roof, trend left to a ledge, and belay at a large, fixed angle.

P3: 150' 5.8. Go up the cool corner system with fun stemming on good holds and "ah ha" gear. Trend right and back left to an old bolt and belay.

P4: 180' 5.8. Continue trending up and right. Try to pick the most obvious corner (it's the cleanest, straightest one) up and reach the "boulder move" on Kiener's Route.

Rack: single rack to 3" seemed sufficient the way I broke these pitches up. On P1, I had read "killer hands" through the roof and ended up at the belay with two #2 Camalots.... If any doubles are needed, I suspect they would be in the 0.3-0.75 range.

Descent: continue with Kiener's Route, and rappel the North Face. Aug 10, 2016
AAJ 1959 [article attributed to Layton Kor]: "Long's Peak. The 'Doorway' route on the east face of Long's Peak starts at a point midway between the Stettner Ledges and Alexander's Chimney. John Hough and Layton Kor made this new route on September 20. The first lead, 40 feet long, ends on a foot-wide belay ledge. Above the ledge towers a huge, rectangular indentation in the shape of a door, which gives the route its name. The second lead involved direct aid to negotiate an overhang. Ten feet higher there is a substantial three-inch belay ledge. About seven feet above this stance we climbed another overhang and the 35 feet above it by direct aid. We then free-climbed the next 25 feet to our third belay ledge. A 120-foot traverse ended on the lower traverse from Alexander's Chimney. The route is well-protected but involved all standing belays. About 25 pitons were used. The ascent took three hours." Apr 27, 2018
