How to Compare National Parks on TrailVerse
Stack up to four NPS parks side by side — weather, crowds, fees, facilities, and best time to visit. How to use TrailVerse Compare and share a link.
Planning guide · TrailVerse
Quick answer
Open /compare on TrailVerse, add up to four parks with search or a preset (Zion vs Bryce, Yellowstone vs Grand Teton), and scroll one table for overview, weather, crowd level, facilities, accessibility, best time to visit, parking, and top activities. Share the URL with ?parks=code1,code2 so your travel group sees the same stack. When you pick a winner, use Quick Actions to open the full park page or start a Trailie plan.

When Compare beats opening ten tabs
You narrowed the trip to a region but cannot choose between two canyon parks, or you want October weather at three different latitudes. Compare is for that decision — not for booking a campsite or reading today's road closure (those live on Recreation.gov and each park's Alerts tab).
Think of it as a scoreboard for planning: same rows, same columns, up to four parks.
Add parks (up to four)
- Go to /compare and search by park name — the picker searches the full 470+ site catalog
- Tap a preset chip (e.g. Zion vs Bryce) to load a common pairing instantly
- Remove a park with the X on its column; add another until you hit four
- No account required — Compare works for guests

Share the comparison
After you add parks, the address bar can include their NPS codes, for example /compare?parks=zion,brca or /compare?parks=yell,grte. Send that link to a partner or save it in your notes — anyone opening it loads the same parks (as long as the codes are valid).
Codes are the four-letter NPS park codes (yell, yose, grca), not the long slug URLs used on park detail pages.
A simple compare → plan workflow
- Shortlist on Explore or Discover (by state, activity, or topic)
- Load finalists into Compare and eliminate on weather, crowds, or facilities
- Open the winner's park page for alerts, permits, maps, and tabs you need in depth
- Draft days with Trailie or the ChatGPT app — see our planning-in-ChatGPT guide
- Book on Recreation.gov using permit links from the park page
What Compare does not replace
- Official closures and hazards — Alerts tab on each park page or NPS.gov
- Trail-level mud and ice — AllTrails or similar once you know the hike
- Live campsite availability — Recreation.gov
- A single "winner" score — you still choose based on your dates, driving time, and priorities
