Anyone can drive past the Rocky Mountains. Colorado Sightseer's active sightseeing and hiking tours take you where you really want to go — out into nature — guiding your every step and providing insights along the way. The company is a local, family-run business, bought and transformed in 2017 by husband-and-wife team Rich and Christin, who wanted a change of pace from their day jobs as a software engineer and a stay-at-home mom. Christin is a fourth-generation Coloradan.

Tours run in small groups of 9–12 guests in touring vans that reach places buses can't go. Guides are mostly Colorado natives or long-term residents, all qualified in First Aid and CPR with regular DOT physicals, and most also hold Wilderness First Aid. The company follows Leave No Trace principles across its national park tours.

All tours depart from Union Station in downtown Denver — meet at the flagpole out front, 17th and Wynkoop Street. The two Rocky Mountain National Park tours and the Peak to Peak tour add pickups in Boulder (Panera Bread, 1855 29th St) and, for RMNP, Estes Park (Town Hall, 170 MacGregor Ave).

Each tour below has its own page with the full route, season and booking link.
