How to get comfortable with Class 3

[CreekRunner]

Since it seems like the thread is pointed toward Morrison, I would recommend Mt. Morrison's southern ridge. The trailhead can be found just of the final exit to Red Rocks concert area on Highway 74. On the final push to the summit, there are some spot that you can push the difficulty to class 2+, 3, or even 4 if you choose to spice things up. Also, it is a pleasant hike with great views of a good chunk of the Front Range.

As AyeYo said, Mt. Glennon doesn't really offer much technicality--there are now stairs in several places--but travelling along the ridge would definitely provide insight to what it feels to be on a "one sided" knife edge.

Assuming you're headed west like everyone else in the metro area... take RT8 towards Morrison past Bear Creek park. Go under 470 and you'll come to a large intersection with Bandimere and a Conoco on the right, take the left directly across from the gas station onto Soda Lakes Rd. There's a parking area immediately at the road entrance. Park there and walk up the obvious stairs, continue following them until you reach the equally obvious bouldering area. There's a very steep class 2+ trail up to the top, but at that point you can just pick your difficulty and make your own route.

Yes. It is a nice lunch break hike. I suggest stay right after the last time one can see the crew's equipment. The ridge has a just-below-the-edge safer trail and the obvious knife edge. Totally doable

Just bumping this thread because people are asking about Class 3.

Close to Denver class 3 experience that is fairly straight forward and not too exposed - Kelso Ridge on Torreys Peak. Also, East Ridge to Bierstadt (although you might want to do a 2 car shuttle so you can descend the standard Bierstadt route).
