A Classic, which the many pin scars prove. Right off the road, and easy top rope access. To get to the summit, hike up the left side, and then up a chimney to the right, or scramble up the right side. The rock is solid, and is south facing enough that in the winter it keeps warm until late in the day.

Getting There

At 8.1 miles from the entrance to Boulder Canyon (the first bridge you cross - see Yahoo! map) there is a small turn off, directly below Practice Rock. You can't miss it.

Just out of curiosity, does anyone know the name or rating of the route marked #1 on the photo? If you look carefully, you can see a thin crack(or even seam?) running straight up from the base to the top of #1. Also, I'm fairly new to Boulder Canyon, if a person finds an aid climb which is just impossible to free, can they hammer in copperheads to send it? Should they leave them fixed? I'm always a proponent of clean aid but sometimes a #1 RP just doesn't cut it. Jan 8, 2002

We went to take a look at Practice Rock today, but we went past it because it's hard to see as you're driving up the canyon. This might help you from doing the same, zero your Odometer at Bolder Falls and it's between 2 and 3 tenths of a mile further on your right. Mar 26, 2002

To reiterate, does anyone have any beta on the climbs labeled #1 and #2 in the topo?

I TRed #1 yesterday and found the bottom to be easy enough (5.7?) but it got substantially harder about 10' below the anchors. Perhaps traversing right would have made it easier, but my rope was caught in a notch above and wouldn't budge. Interesting times... Anchor-wise, there's an old 1/4" bolt up there and lots of places to put gear. But be careful, some of those blocks are loose and most of them are detached. Long slings would let you sling a tree or some of the farther blocks.

#2 looks like a huge chimney with a couple of awkward chockstone problems. Could be interesting if you're into that sort of thing. Anchor will involve gear or runners from farther trees and blocks. Jul 15, 2005
What is the rock directly across the street from Practice Rock with the start of routes being on top of this terrace about 100 feet up. There is a slick corner that is wicked fun to climb? Any help appreciated. Sep 2, 2005
The crag across the street is Bell Buttress. The slick corner is Cosmosis 5.10 (great climb). Sep 25, 2009

#2 is a huge chimney. One of my cams dropped down into the middle, so I scrambled up from the bottom. Can't be harder than 5.5. Jan 31, 2012
MISSING RED GREEN AND YELLOW WALLET! I lost my wallet at the Practice Rock/ Bell Buttress/Bowling Ally parking turnout on Saturday 11/4. My name is Joshua Richardson, my Maine State ID is in there as well as my passport and other valuables. If found, please call or text me at 207-318-6093. Nov 6, 2017
