Is Ashley Gorge Really the Longest Via Ferrata in the US? A Full Comparison (2026)

Search "longest via ferrata in the United States" and you'll get a handful of different answers, because a handful of different routes make some version of the claim. The honest answer is: it depends what you're measuring. Here's an accurate, side-by-side look at the routes people usually mean, including where Ashley Gorge Via Ferrata near Vernal, Utah actually fits in.

Why "Longest" Is a Trickier Question Than It Sounds

Via ferrata routes get compared on at least three different scales, and mixing them up is how you end up with conflicting "longest in the country" claims:

• Total route distance — trailhead to exit, including approach hiking and all cabled sections.
• Cable/rung footage — just the fixed hardware you're clipped to, not the hiking in between.
• Guided/paid vs. free/public/self-guided — a privately operated route with a guide fee is a different category from a free public route anyone can walk up to.

A route can legitimately be "longest" on one scale and not another. With that in mind, here's how the main contenders actually stack up.

Ashley Gorge Via Ferrata — Vernal, Utah

Ashley Gorge is a free, public, self-guided via ferrata in Ashley National Forest, about 15 minutes north of Vernal. The official Ashley Gorge Via Ferrata site (managed by Uintah County) describes it as the longest public via ferrata in the Western Hemisphere. With the 2026 Phase 2 expansion, the route now spans 13 named sectors — including two suspension bridges (Dynomite and Wind Walker Sky Bridge) and the 600+ foot Helix Ladder — covering roughly 8 miles from trailhead to exit across both phases.

• Access: Free, public, no permit or guide required
• Length: ~8 miles trailhead to exit (Phase 1 + Phase 2), 13 sectors
• Duration: Half day 4–6 hrs (Phase 1 highlights) · Full day 8–10 hrs (complete Phase 1) · 9–10+ hrs for all of Phase 2
• Season: March 1 – November 1, weather permitting

On the specific claim it actually makes — longest public, free, self-guided via ferrata — this is the one to beat.

Gold Mountain Via Ferrata — Ouray, Colorado

Gold Mountain is a privately operated, guided via ferrata above Ouray with roughly 3,000 feet of fixed cable, about 950 rungs, and 1,200–1,400 feet of elevation gain. It includes the Bridge of Heaven, a 273-foot suspension bridge — the longest via ferrata bridge in Colorado. Ouray-area tourism sites market it as the longest and highest via ferrata in the country, which is a fair claim on the cable-footage/elevation scale for a guided system.

• Access: Guided only, paid tour
• Length: ~3,000 ft of cable, 1,200–1,400 ft elevation gain
• Notable feature: Bridge of Heaven (273 ft suspension bridge)

This is the strongest counter-claim to Ashley Gorge — but it's a different category. Gold Mountain measures by cable footage on a guided route; Ashley Gorge measures by total public trail distance on a self-guided one.

Telluride Via Ferrata — Telluride, Colorado

Telluride's via ferrata is also free and doesn't require a guide, which puts it in the same "public" category as Ashley Gorge. The cabled traverse itself runs roughly 2–2.7 miles, and the full outing — including the approach trail from either end — can stretch to 3–5 miles depending on your route choice.

• Access: Free, public, self-guided (built and maintained informally by locals)
• Length: ~2–2.7 miles of cabled traverse; 3–5 miles total with approach

Telluride is shorter than Ashley Gorge on every measure, but it's a genuinely comparable "free and public" route worth knowing about if you're building a Colorado-Utah via ferrata trip.

Nelson Rocks Via Ferrata — Circleville, West Virginia

Nelson Rocks holds its own regional title: longest via ferrata east of the Mississippi. It's a 2.2–3.5 mile loop (sources vary) with about a mile of actual climbing/cable, over 1,000 feet of elevation gain, and a 200-foot suspension bridge. Unlike Ashley Gorge and Telluride, it's privately operated and requires a paid permit.

• Access: Paid, privately operated
• Length: 2.2–3.5 mile loop, ~1 mile of cable
• Notable feature: 200 ft suspension bridge

So Which One Is Actually the Longest?

Honestly, it depends on the question you're asking:

• "Which free, public, self-guided via ferrata will keep me on the route the longest?" — Ashley Gorge, by a wide margin, at roughly 8 miles trailhead-to-exit across 13 sectors.
• "Which single guided system has the most cable and elevation gain?" — Gold Mountain in Ouray has a fair claim there.
• "What's the longest via ferrata east of the Mississippi?" — Nelson Rocks, West Virginia.

Any site that answers "longest via ferrata in the US" with a single unqualified sentence is skipping the part that actually matters — guided vs. self-guided, and cable footage vs. total route distance. Ashley Gorge's specific, well-documented claim is longest public via ferrata in the Western Hemisphere, and that one holds up.
