Every mountain, verified.

The problem we built this to solve

If you've used AllTrails or a similar app, you already know the frustration: a trail marked "moderate" that's actually a scramble, a summit route with three different reported distances, reviews that read like they were written about a completely different mountain. Crowdsourced outdoor data is only as good as whoever last edited it — and nobody's checking their work.

PeakSeeker exists because the mountains themselves are unambiguous. A summit has one elevation. A route has a real, documented grade. A resort's vertical drop is a fact, not an opinion. We built this site around the idea that terrain data should be sourced the way you'd source anything else you're trusting your safety to: from the people who actually measured it.

What "verified" actually means here

Every resort and summit on PeakSeeker is built from real, citable sources — official resort operators, government and land-management data, Wikidata and Peaklist for elevation and prominence, and established climbing and ski references for route and grade information. When a fact can't be confirmed against a real source, we leave it blank rather than guess. You'll see this on individual pages as a null or "not yet available" field — that's not a bug, it's the alternative to making something up.

How this compares

The other apps in this space aren't badly built — they're built around a different bet. AllTrails, Gaia, and onX all optimize for coverage: more trails, more layers, more crowdsourced check-ins, as fast as possible. That bet has a cost, and it shows up as the same three complaints wherever people talk about these apps: data that's stale or was never right to begin with, offline maps that either fail to download or sit behind the paywall exactly when you need them most (in the backcountry, with no signal), and features that were free last year quietly moving behind a subscription this year.

PeakSeeker makes the opposite bet on all three. Smaller, verified coverage instead of an unaudited firehose. Once you've opened a resort or summit page, it and the core dataset keep working with no signal at all — no separate offline tier, no download-and-hope — because the basics shouldn't disappear the moment you actually need them. And we're not going to build a business by quietly moving today's free features behind tomorrow's paywall; see Our Promise for exactly what that means in practice.

What's on PeakSeeker

• Resortsreal terrain breakdowns, named lifts and runs, live conditions, and avalanche danger ratings pulled from official sources (avalanche.org in the U.S., Avalanche Canada north of the border).
• Summitsverified elevation and prominence, real ascent routes with their actual technical grades, first-ascent history, and nearby resort context.
• Tripsplan a trip, invite people, build a day-by-day itinerary, and keep the group's plans and photos in one place.
• Your logtrack your own days, sessions, and ascents, tied to real mountains rather than a generic checklist.
• The conciergeask a question about any resort or summit in the catalog — look for Scout, the chat icon in the corner of the screen — and get an answer sourced from that same verified dataset, not a generic AI guess.

Who this is for

People who want to trust the number on the page — whether that's a vertical-drop figure before booking a trip, a route grade before committing to a climb, or an avalanche rating before heading into the backcountry. If you've ever had an app's "easy" trail turn out to be anything but, PeakSeeker is built for you.
