Get details for a single AllTrails trail by its numeric trail id. Returns name, location, length, elevation gain, difficulty, rating, route type, and (at higher detail levels) route geometry. Set compact=true for a slim projection (name, overview, length in m+mi, elevation gain, difficulty, rating, route type, location) — recommended unless you need the full record or geometry.

Get user reviews for an AllTrails trail by its numeric trail id. Set compact=true to return just { user, rating, comment } per review.

Get photos for an AllTrails trail by its numeric trail id. Set compact=true to return just { id, title, likeCount, user, uploadedAt, url } per photo — the url serves the actual image.

Export an AllTrails trail's route as a GPX 1.1 document (track points with per-point elevation), built from the trail's offline-detail route geometry. Returns raw GPX XML suitable for saving to a .gpx file or importing into navigation apps.

Get the weather overview for an AllTrails trail by its numeric trail id.

Search AllTrails by name. A free-text query goes to the suggestions endpoint the alltrails.com search box itself uses — relevance is good and the limit is honored. Results may mix record types (trail, poi, area, city, …); pass types=["trail"] to narrow. lat/lng are accepted for backward compatibility but verified ignored by the API (2026-07-02) — results carry an implicit account/IP geo bias instead. Without a query this falls back to the legacy explore search, which returns trails anchored to the signed-in account's location. Set compact=true (strongly recommended) for slim summaries capped at limit client-side.

Resolve a place name to AllTrails location records — country / state / city / area / point of interest — with each one's kind, coordinates, URL slug, and disambiguation label. Useful for pinning down which "Oregon" (state vs the towns) or getting a place's coordinates/slug. NOTE: the returned id is an Algolia search id and is NOT the id the trail-listing tools take; to find trails for a place, feed the resolved name back into alltrails_search.

Get the signed-in AllTrails user profile (via /api/alltrails/me). Requires a signed-in session.

List an AllTrails user's saved lists (favorites, custom lists). Defaults to the signed-in user; pass a userId to target a specific public profile.

Get the trails saved in an AllTrails list by its numeric list id (from alltrails_list_user_lists, or a public "list" record from alltrails_search). Items are sparse references: each carries a trailId (hydrate with alltrails_get_trail), the curator's order, and any notes — not trail details. Set compact=true for slim { trailId, type, order, notes, addedAt } entries sorted by order.

List the trails an AllTrails user has marked completed. Defaults to the signed-in user; pass a userId to target a specific public profile.

Get an AllTrails user's activity feed (recorded hikes and posts). Defaults to the signed-in user; pass a userId to target a specific public profile. Without a feed argument this returns the feed DIRECTORY (the available feeds: local, timeline (following), personal (own posts)) — pass feed to get the actual items. Set compact=true for slim projections.

Round-trips a small public www.alltrails.com URL (/api/alltrails/v3/trails/10236086?detail=basic) through the fetchproxy bridge and returns diagnostics: the bridge's role (host/peer/null), port, version, the elapsed round-trip time, and a plain-English hint distinguishing 'bridge never came up' from 'extension not connected' from 'real www.alltrails.com-side problem'. Call this when a real tool fails and you want to know which hop broke. Read-only, no auth required.
