Denver Adventures was founded in 2005 by Stefan Van der Steen, an outdoor adventure enthusiast with a dream of bringing people closer to the outdoors in a fun and active way. The Rocky Mountains close to Denver are the perfect platform for easy access to a wide variety of terrain and natural scenery to suite anybody's needs. Every one of our adventures invites you to enjoy and use nature's wonders but at the same time respect, admire, and learn from it.

Our team of experienced guides has had more than its fair share of enjoying the Rockies. Over time, they all have built extensive knowledge of physical exercise, altitude, trails, parks, and natural attractions but are also active participants of races and volunteer efforts. Stefan, for instance, focuses on endurance events such as The Triple Bypass, Ultra100, Olympic distance triathlons, marathons, and even an IronMan!
