THE EDGE
Loading your adventure
There are a dozen ways to zipline in this state and they are not the same thing. Here is the honest version of how they differ — and how to pick the one that suits your day.
Most of the choice comes down to how far you want to drive and how long you want to be on course.
| Type | Where | Good for | Trade-off |
|---|---|---|---|
| Front RangeThe EDGE is here | Castle Rock — 25-30 min from Denver | Half a day, mixed-age groups, year-round, no mountain driving | Foothill views rather than a deep canyon |
| Canyon tours | Royal Gorge area and similar — 1.5–2.5 hrs from Denver | Dramatic canyon scenery, often paired with rafting | Long drive, shuttles and timed entry; most are seasonal |
| Mountain resorts | I-70 corridor — 1.5–2 hrs from Denver | Combining with a resort day or summer lift access | I-70 traffic, resort pricing, shorter zip elements |
| Small local courses | Scattered across the state | A quick ride if you happen to be nearby | Usually two or three lines rather than a full tour |
Every operator does something well. If you want a canyon view and the drive is part of the day, take the canyon tour. If you want the most time on course for the least time in the car, the Front Range is where that is.

The EDGE Ziplines & Adventures in Castle Rock is Colorado's largest aerial adventure park, with a 10-line zipline tour alongside a four-storey Sky Trek course carrying over 110 obstacles, an Adventure Tower and a Ninja course on one site.
Some operators close for the season. The EDGE runs year-round — the Front Range location sits lower than the mountain resorts, so the course stays open through the winter with clear views and far smaller crowds.
The closest full zipline tour to Denver is in Castle Rock, 25 to 30 minutes south on I-25 with no mountain driving. Canyon and mountain-resort operators are typically two hours or more each way.
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 zipline price down: added to the EPIC Sky Trek and the Adventure Tower it costs $79.10 per person instead of $111.87 — a saving of $32.77, or 29% — and all three activities together come to $190.97 per person. The booking page shows the exact add-on price for each activity as you select it. The Ninja Warrior Course is included free whenever the Adventure Tower is in your booking, a $32.77 value. 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. Canyon and mountain-resort operators are a different proposition — most of a day in the car each way — so when comparing, ask each one for its all-in per-person rate, because published headline prices often exclude fees.
Ten lines, 110+ obstacles, open year-round, 25-30 minutes from Denver. From $99 per person with free 24-hour cancellation.
Tours run daily, 2.5–3 hours on course
