And Maggie's Kitchen in Ouray. We just made day trips to each and walked around town so can't tell you much outside. Box Canon Falls in Ouray was pretty cool. I can give more trail recs in Silverton but it's a bit further down the road from Ouray. Haven't been offroading, just hiking.
I'm not sure Imogene is currently open. Had a friend scheduled to run a race over the pass 2 weeks ago and something broke due to summer monsoons. Not sure they fixed the road yet.
