Crested Butte might be my favorite town in this guide. During summer and fall, drive Kebler pass for stunning wildflowers and fall colors.
If you're camping, check out Mt Crested Butte campground. Tent camping only, first come first serve. If you go during spring, you'll wake up surrounded by wildflowers.
Butte Bagels, just go. Trust me it's worth the line.
For unique and delectable pizza, try The Secret Stash.
For the perfect wildflower hike, go to Rustler's Gulch. The road is rough, a 4 x 4 is recommended. But the hike is worth it.
