From Boulder: drive up Boulder Canyon to Nip and Tuck crag. Continue past Nip and Tuck for 0.3 miles to a large RTD parking area/pullout on the left. Park at the far west-end of the parking area. Cross the creek at a 20-mile per hour sign and look for a rock cairn on the south side of the creek. Angle up and right along a lower rock wall to reach the upper (Retirement Rock) wall.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Retirement Rock:
The start is the same as Early Bird Special. Climb up to the first bolt on Early Bird Special then move right to the second bolt. Fire straight up on fairly good holds to the crux around the fourth bolt. Power past the fifth bolt and reach a two-bolt anchor. Good route and wonderful face climbing. Should clean up with more ascents. ...[more]Browse More Classics in CO
Question on the approach: we crossed the creek at the 30 mph sign (not 20, per the description) across from Nursing Home, and came to a clearing with a cairn. However, couldn't see a path and didn't want to crash through the rather thick brush if there is a trail somewhere...I prefer to limit impact on the foliage. Is there a path/trail that I missed, or do you have to bushwhack through?
I'm not sure of the speed limit sign, but you should cross at the far west (up river) end of the parking lot. There used to be a cairn on a big rock on the other side. Then head up a short steep hill, and then angle up stream. The trail grows in and I may need to get there and clip the growth back.
I didn't read the trail beta and found the "direct" uphill approach pretty nasty. The river crossing was below the kneecap, but man, the overgrowth! I should have read/found the trail, but didn't. That said, if you like red rasberries, man is this the place for you. Big, fat rasberries everywhere, all you can eat. Enjoy it, it's as thick as they get.
If you do go here, please do everyone a favor and take a large wire brush - the routes could use a little more cleaning. Since everyone has slightly different styles, 1/2 of the available/usable/legit holds are not brushed clean and are quite dirty on a few routes. The moves are fun though, so they clean up nicely.
With a better approach and cleaner rock, this would be a worthwhile after-work crag, but right now, it suffers the lack of "full development."
