The Lion's Den Rock Climbing
Bouldering at the Den.
The Lion's Den is one of Boulder County's premiere moderate bouldering areas in a beautiful and remote setting in the mountains outside of Lyons. The area is home to 40-70 odd boulder problems ranging from V0-V6/V7, with a hand full of absolute classics like Cheeseburger
, Hyperion Probiscus, Ben Slab, and the Center Route in the Corridor
. Located on the top on an unnamed mountain and facing roughly southwest, this is a great place to spend and afternoon pretty much year round. A moderate but beautiful hike all but assures that you will have the area to yourself, so get out there!
Bernard Gillett's new "Rock Climbing St. Vrain Canyon" from Sharp End Publishing has all of the older established lines for the area in the back of the book.
From Lyons, continue on US Hwy 36 towards Estes Park. Approximately 4 miles up the canyon turn left at "Shelly's Cottages," but take the road to the left of Shelly's driveway, and follow it to its end at a parking lot (approximately 1.5 miles). From here, hike the road past the gate, the river wall, and the reservoir. About 250 meters past the reservoir on the left is the beginning of the trail, which is faint off the road, but is well worn in the trees. The trail switchbacks about 5 full (right/left) times (there is a yellow Forest Service Marker (eds. which may be gone) at the end of the switchbacks and the Prow stands proud about 50 meters behind the marker) before heading towards the summit and the main area.
: there is a "No dogs allowed at Hall Ranch" sign right before the boulders came into view

To get here, I followed a set of directions on this website and another website. The initial trail had one section that was tricky to navigate, but there is a good trail and cairns still present on the trail. I ended up passing the area and was told by horseback riders (fortunately) that I had passed it. I never encountered a yellow Forest Service sign. Once you find the area, it is really easy to find your way around and explore. Was decently warm for a sunny winter day also.

I also got lost on the way here. The trail takes off to the left at the end of a left-right "S turn" in the road right after the reservoir. If you reach the Sleepy Lion trail, you've gone too far. Also, there was no yellow forest service sign. Continue straight up (Northwest) past the fifth right turn. If you reach the large meadow, you've gone too far.

I almost got lost as I reached the open space boundary and a "no dogs allowed at Hall Ranch" sign right before the boulders came into view, which isn't mentioned anywhere and threw me off. Has that sign always been there and, if so, have people been fined or anything for having dogs?
