There are no shortage of beautiful hikes (or great breweries for after)! We recommend using alltrails.com to find hikes that fit the distance/difficulty you are looking for! :)
Mountain town about an hour away from Monarch Casino & Spa! Great boutique shopping and restaurants, and they offer a free gondola ride up the Mountain in the summer!
There are lots of Arkansas River white water rafting opportunities in and around the Idaho Springs area!
Gorgeous reservoir 45 minutes from Monarch Resort! Grab drinks at the marina, or rent a bike or paddle board!
