The Solar Dome is a small, non-descript crag uphill and a bit West of The Upper Security Risk. Really, it looks like a small, improbable blob with little to offer. In fact, The Solar Dome is a well-developed sport crag on short but typical Boulder Canyon granite. Most routes are under 70 feet in length and have been well-bolted. Surprisingly good climbing can be had for such short routes. Since the crag sits on top of the hill, it gets good sun all day long. However, it also picks up most of the bad weather blowing through Boulder Canyon. On a warm summer day, The Solar Dome is a great place to catch the rays and pick off a few good climbs. The climbing is largely 5.10 to 5.12, although a few very moderate lines have been installed. Presently, there are at least twenty routes in place with link-ups possible for many of these.

Getting There 

The most hassle free approach to The Solar Dome is to hike up from The Upper Security Risk crag. This adds about 10 minutes to the hike up from Boulder Canyon making the entire walk at least 45 minutes. In the past, it was possible to approach The Solar Dome from the North, parking on the hill just before it drops down to Dream Canyon parking. This entails crossing private land, which has caused some trouble in the past several years and is to be avoided if possible. That said however, we have used the Northern approach after first checking with the landowners.

This is a combination of Walking On the Sun and The Homesteader. This combines the two routes into a good route for 5.10 climbers.The starting crack provides fun holds up the crack for the first three bolts. There is a rest ledge here before you continue up the well-featured rock on The Homesteader to the left. I found the first 3 bolts hard to clip, but my partner is taller and had no problem with the clips....[more]   Browse More Classics in CO

Do not think that the long hike will mean fewer crowds! It's a good spot to meet and greet the sport climbing crowd.

Climbed in short sleeves on Nov. 20, a day when the Boulder high was forecast around 55 (don't the know actual turned out to be down there but it felt warmer than that here.)

Do the climbing community a favor, drill a few more holes in this and return it back to the rubble heap it is.

Hmm, no one there (besides me/partner) on a lovely 50 degree (in Boulder, sunny, low wind) late fall Saturday. I guess crowds come and go.
