I rode that a few years ago. The views are the best thing about it. Fun trail especially after the climb up Gothic Pass. I also rode snodgrass and it was a lot of fun. I would like to get back and ride Doctors park, they say it's better than the 401 due to the technical part of the the last few miles.Made a multi day trip to Crested Butte.
Only was able to ride one trail due to rain, and it was very muddy.
Did the 401 Trail. Considered one of the big Colorado/West USA rides. It's pretty tame, solid blue green/blue. The thing that makes it difficult is that during the summer time the wildflowers are 4' tall and makes it hard to see what's coming up. Rained for over 12 hours the day before so there was lots of mud on the trail.
Don't have many pics. Took this one of my fiancé while waiting for her to catch up.
I would really like to do the monarch crest trail loop in Salida, it's just hard to get time to get down there and my wife doesn't ride, so I can't con her in to going.
