Gregory Canyon (including The Amphitheatre)

Description 

This is the northern-most section of the the Flatirons which may be lumped together to help you find your way here. Included in the area is the better known Amphitheatre and some of the less-well known crags here (like 3rd, 4th, 5th pinnacles). Apparently, according to Rossiter, there is even a granite crag in this canyon. One route from this canyon even made the cover shot of a Boulder non-climber publication.

Some shade can be found at some of the crags for those seeking cooler cragging in the hotter months. None of these routes are long here.

Access can be most readily obtained by parking in or near the Gregory Canyon Trailhead. Parking is popular here and, as a result, limited. Note, parking here does cost for non-Boulder County registered vehicles. 2006 was still $3/day and $25/year. However, street parking nearby and parking at Chataqua (0.6 mi) is free.

Over the years, there have been some crag closures for raptor nesting. So, check out the details with Boulder Mountain Parks. The Access Fund website is not always accurate here.

Also, for those wandering around with little kids, this is bear and mountain lion territory. Be careful.

There is also significant poison ivy in the area for the sensitive.

Getting There 

US 36 to Baseline. Go W past 6th Ave and look for the trailhead area on the left. Parking is also available on 6th, 7th, 8th, and at Chatauqua.

In spite of its name this is a surprisingly good route. Due to the Poison Ivy challenge in mid route we opted for soloing the route rather than drag our rope through the evil weed.Start on the East face immediatly left of the large overhang/dihedral that splits the face. Climb up the gully under the overhang and arrive at a large ledge. The ledge is indeed covered with vegetation, with lots of Poison Ivy. But, this time of year you can easily pic...[more]
