Colorado 6-Zipline Adventure: Rocky Mountain's Longest Lines

Fly across Colorado's longest ziplines at 60mph between the trees

A 3-hour zipline adventure in Colorado's Rocky Mountains where you ride six lines ranging from 850 to over 1,900 feet long at speeds up to 60mph, suspended 30 to 250 feet above the ground. The course includes scenic uphill hikes between ziplines, a certified guide, safety equipment, water refills and snacks. Minimum weight is 40 lbs; maximum is 245 lbs, strictly enforced on a calibrated scale before the adventure begins.

The Experience

The course spans more than 6,000 feet across a nature park at close to 9,000 feet elevation. You'll ride the two longest and two fastest ziplines in Colorado, with individual lines stretching from 850 feet to over 1,900 feet. Between runs, short scenic hikes move you uphill through the terrain. A certified guide leads the group, handles all safety equipment setup, and stays with you throughout the 3-hour adventure. The operation runs rain or shine.

Speed builds across the course: lines accelerate you to 60mph as you cross meadows and fly through trees, suspended anywhere from 30 to 250 feet above the ground. Water stations let you refill bottles between ziplines, and snacks are provided. The physical demand is real—good cardiovascular fitness is required because of the hiking component—but the course welcomes all fitness levels once you meet that baseline. Weight limits are strictly enforced: a minimum of 40 lbs and a maximum of 245 lbs, measured on a doctor's scale before you start.

Children 17 and under need a parent or guardian present on the course. Ages 5 to 13 require a paying adult ziplining alongside them; ages 14 to 17 need a guardian present but not actively ziplining. The adventure operates with minimum passenger numbers, so there's a small possibility of cancellation after confirmation if the group doesn't meet requirements—in which case you'll be offered an alternative date or a full refund.
