Ranger-led tours sell out at release. Get alerted the moment one comes back.

Some well-known tours don't resolve to a stable recreation.gov tour id, or don't book through recreation.gov at all — so a watch would be selling false hope:

• Carlsbad Caverns — King's Palace — King's Palace has a real recreation.gov tour, but it didn't resolve to a stable tour id within a search-verification pass — we skip rather than guess.
• Carlsbad Caverns — Left Hand Tunnel — Left Hand Tunnel's recreation.gov tour search returned no results during verification — we skip rather than guess.
• Fort Sumter Ferry — The Fort Sumter ferry books through a concessioner (Spirit Line Cruises), not recreation.gov — we don't watch it.
• Hoover Dam Tours — Hoover Dam tours book through the Bureau of Reclamation and its concessioner, not recreation.gov — we don't watch it.
• Alcatraz — Alcatraz tickets book through Alcatraz City Cruises, not recreation.gov at all — out of scope for this watch mechanic.
• Glacier — Logan Pass Shuttle — Glacier dropped its vehicle reservation for 2026 and replaced it with a ticketed Logan Pass shuttle, which is a real recreation.gov ticket facility we can read. But the facility sells two services (West Side from Apgar / Lake McDonald, East Side from St. Mary / Rising Sun) and the availability data doesn't say which is which — so we'd be guessing which tickets we were watching. We skip rather than guess, and we'll add it when the 2027 booking window opens.
