Ten Ziplines Over 320 Acres, Thirty Minutes South of Denver
A guided run on town-park land in Castle Rock, with short hikes carrying you between the platforms.
Castle Rock sits on high ground between Denver and Colorado Springs, where the land rolls out in scrub oak and dry grass. The EDGE strung ten ziplines across 320 acres of it. Two guides run each group, and the group tops out at eight. The course sits inside a town park. Non-riders can watch from the ground.
The tour runs two to three hours. Harness, helmet, and gloves come with it, and every session is booked ahead of the day.

The ten lines add up to about a mile and a half of cable. The longest drops put you near 110 feet off the ground, and the quickest carry you to around 50 miles an hour. Between platforms you walk on uneven ground, and that walking is what stretches the session to two or three hours. fauxpainter1, who rode in July 2022, put a finer point on it: "There is a lot of physical activity hiking between the 10 lines especially the upper incline steps to get to the last line." Two guides stay with the group the whole way. On a clear run the view reaches the Front Range and Pikes Peak.
Getting There and Finding the Office
📍 The EDGE runs inside Philip S. Miller Park, a town park at 1375 West Plum Creek Parkway in Castle Rock, about a thirty minute drive south of downtown Denver. Parking at the park is free.
Coming in, bear left and drive to the far end of the lot. The office sits past the turf soccer field, under the climbing tower, and you want to be there thirty minutes before your slot. Turning up late can cost you part of the tour or move you to another time.
Everyone signs a waiver before gearing up, and anyone under 18 needs a parent or guardian to sign it.
Whether You Clear the Bar
The ziplines carry a fixed range. Riders need to weigh between 70 and 250 pounds, and the minimum age is seven. The operator is plain about the reason: guests have to fall inside that weight range to make it across each line.
Mobility counts as much as the numbers. Reaching the lines means moderate hikes over uneven ground, and riders need full use of their arms and legs along with the ability to climb stairs. The operator does not clear pregnant travelers, or anyone with a broken limb, a severe leg or back problem, or another serious illness. Anyone who has been drinking is turned away.
Fear of heights is a separate question. Guides start nervous riders on the shorter, lower lines and let them work up from there.
Weather, Season, and the Morning Slot
Light rain does not stop the tour. The EDGE closes for lightning, for sustained winds over 25 miles an hour, and for severe weather, and a cancellation on their side comes back as a full refund or a free reschedule. Cancelling on your own side works differently. Bookings are non-refundable. Afternoon thunderstorms are the Front Range summer pattern and usually clear inside 30 to 45 minutes, which is the argument for a morning slot.
Peak season runs April through October. Winter hours are limited, typically December through February, and the crew will run in temperatures down to about 35 degrees when conditions are safe. Dress in layers. Closed-toe shoes are required in every season.
