Why Boulder comes to The EDGE
Colorado's largest aerial adventure park — ten ziplines, a four-storey Sky Trek course with 110+ obstacles, and no mountain drive to get here.
A different kind of high
Boulder has rock. This has ten ziplines and 110+ aerial obstacles — a day out that is nothing like your usual.
No I-70 nonsense
South on US-36 and I-25 rather than west into canyon traffic.
Guided, not DIY
Every tour runs with trained guides — no route-finding, no gear to own.
Good for visitors
When family are in town and the Flatirons have been done, this is the next move.
All ages on one site
Ziplines, Sky Trek, Adventure Tower and Ninja course together.
Year-round
Open through the winter, and far less exposed than anything above 8,000 feet.

Local tip for Boulder
The US-36 to I-25 merge through Denver is the whole journey. Leave before 9am or after 10am and you will miss the worst of it — the Castle Rock half of the drive is almost always clear.

Is it worth the drive from Boulder?
It is about an hour each way for two to three hours on course. Most Boulder guests make a half-day of it and stop in Castle Rock on the way home. If you want something closer to a full adventure day, add Sky Trek to the zipline tour.
How much does ziplining at The EDGE cost?
The 10-Line Zipline Tour is $99 per person on weekdays, or $111.87 with the 13% Castle Rock city access fee included. Combining activities brings the price down: the zipline and the EPIC Sky Trek together, booked as Zip & Play, come to $157.07 per person instead of $178.54 booked separately — a saving of $21.47, or 12%. The booking page shows the exact add-on price for each activity as you select it. Weekend and peak departures are set at a higher rate, and further discounts are often available depending on which departure you choose — the price shown when you pick a time is the price you pay.
What it costs
The 10-line zipline tour starts at $99 per person. Add a second or third activity and the whole day costs less than booking them separately.
