The mountain shop is the first of the Rocky Mountain National Park shops you can hit when you enter Estes Park on Highway 34. Most of the locals know it as the old pewter place and this store has everything. Don't forget to check out the basement for some good deals on camping gear and clothes.

Kirks has everything you need for fly fishing and a good selection of camping gear as well. He also has the mugs, shirts and odd stuff I know my wife is always looking for. Just like the belt with the brown trout pattern she got me for my birthday.
