This has become my go-to spot for dispersed camping near Boulder. There are a ton of sites right after you pull off Sugarloaf road. The first few might be taken, but keep going and you should find one. Keep your eyes peeled for the road as it's easy to miss, but GPS should take you right there with the directions in the app. The road gets rougher the further you go and you'll definitely want some clearance, but I was totally fine in my stock Subaru Forester.
