Getting weather forecast...


Rabbit Mountain offers a high potential of bouldering close to Boulder. Though mainly a winter destination for it is south-facing, it is climable year-round. The developed rock is a lot like Carter Lake in some areas (great), but a solid Dakota Sandstone in others(perfect). It has long 25-foot cliff bands offering lots of highball ventures over good landings, and free standing boulders with overhangs and slabs. The Development of the Mountain is understood to be new, for we have cleaned years of dirt out of the most obvious problems. Though just parking at this Open Space Park one can see the climbing possibilities, which makes me think of course people have climbed here. Approaches to and around the area are on faint off-trail paths, not Boulder Park trails, and the fact that you are visible on the naked hillsides from the parking lot, make this a potential access problem, though none have arisen. Mega-classic bouldering lines are already for the taking.

Getting There

From Boulder, head north on US 36 towards Lyons. At the light make a right towards Longmont. Go about a mile or more and make a left on 53rd Street. A brown sign saying Rabbit Mountain Open Space accompanies this turn. Drive another few miles to a Public Parking Area for Rabbit Mountainon your right, with a large lot, bathrooms, and picnic tables. Park here and hike to boulders.

I must add that Rabbit Mountain has seen it's most recent developement by Mike Freischlag, Pete Zoller, Patrick Wild, and Phillip Benningfield. These guys have climbed some proud and beautiful highballs in the area. I've merely lent a hand on the smaller stuff. Apr 11, 2005
I haven't seen any bolts, but there are a couple of little red arrows painted on the base of some of the problems. Any idea who could have done this, Bob?

I visited Rabbit Mountain and only found a few problems- it seemed all the good stuff was beyond a "No Trespassing Sign"The rock quality seemed good but not much was available, did I miss something? Any help would be much appriciated.Thanks Apr 16, 2005
There is a great smaller area near the parking lot where a faint trail leads from by the bathrooms straight to where the cliff bands comes down to meet the plain, looks like a little cave from a distance. Not 200 yards. Maybe 8 problems, one being a 3-star V2 Arete. The majority of the problems are on the mountain just South (up & right) of where you park, you'll notice the giant cliff bands, and bigger-than-they-look boulders. Hike the main trail up and drop in from the top, or hike direct. The good looking stuff to the North (left) is private. Apr 17, 2005
It goes without saying, but please refain from doing bong hits before your bouldering session. Also, you might want to lay off the alcohol and barbituates, because the only way that you might have mistaken this area for "classic" is if you were simultaneously doing all three at once. These things are best saved until you are safely at home on the couch so as to not alter your perception significantly. There does appear to be some good bouldering sectors on private land; however, the stuff in the open space is limited to a fifty foot wide sector with maybe five good problems. This place is not worth your time unless you are willing to trespass, which is always a good thing to do on a Saturday afternoon when the landowners are out on their porch. Thanks for nothing! stoners. May 7, 2005
Ok, so I re-visited this place, and walked to the obvious cliffband (south east of the parking), and I still don't get it. While there were several (4?) slightly-more-than vertical lines that were nice-looking, and 1.5 ok overhanging line(s) on short boulders, I didn't see

"Mega-classic bouldering lines [that] are already for the taking."

or even

"...lots of highball ventures over good landings, and free standing boulders with overhangs and slabs. "

Can anyone be more specific? Or am I the only one that hasn't figured out the joke?

P.S: There are (not surprisingly) rattlesnakes here. May 17, 2005
Try parking on the east side of Rabbit Mountain off of 75th Street. This is the area Mark Sonnenfeld developed. Turn off of Ute Highway/ 66 at a Czech restaraunt, then drive north on 75th for a couple of miles. Turn left just before 75th jogs and changes names. It is a worthwhile area. May 18, 2005
Sorry if I had to drag anyone from their worn out routines to climb somewhere they haven't. My mistake. Is new bouldering a bad thing? Can we have a website where honest contribution is a good thing. It's a database, people. So, this place gets me exicted. You didn't see what I've seen. You didn't climb what I climbed. You didn't climb the best of what was there, if you had, a nice day trip to Lyons would not of rubbed you so wrong. Was it that bad? Were the climbs "mega-classic" in the sense that John Gill holds its history in the back pocket of some worn out pair of Wrangler jeans? No. Are they "mega-classic" in the sense of; they're better than most Boulder County highballs, if you're interested have fun and be one the handful of people do have done them? YES! May 20, 2005

There's only a handful of decent problems, we'll say 6. But the area gets great sun in the dead of winter. Directions: when you are at the parking lot, hike the obvious trail that heads north. There will be a trail that takes a right about fifteen minutes up the trail, take it. Hike another 10 minutes and head north down the hill at a sign talking about birds. This will take you down to the cliff band. Head east along the cliff band for 10 minutes, fine bushwacking, the best wall there is very obvious. Out of 5 stars. Left line V7? Crack to pocket V4 2-star, obvious crack V3 3-star, right problem V4 3 star. All are highball, 3 or 4 pads recommended. In a corridor just to the right of these problems are 3 problems. The right most being what would be called classic, The Charlie Sheen (V6, V7) Worthy of a once a year visit, but that's about it. I will upload some photos later. Feb 14, 2011
