Overview
- Glacier National Park ends its park‑wide vehicle reservation but will run a ticketed‑only shuttle on Going‑to‑the‑Sun Road, with tickets released starting May 2 and some next‑day tickets from June 30, plus a three‑hour parking cap at Logan Pass beginning July 1.
- Yosemite drops advance reservations for 2026, including the February–March firefall period, relying on real‑time traffic monitoring, temporary parking management and added seasonal staff during peak congestion.
- Arches removes its timed‑entry system for 2026 and advises visitors to enter early or later in the day and to seek less‑crowded areas if lots fill.
- Rocky Mountain National Park keeps timed entry from May 22 through mid‑October, with limited daily entry windows available via Recreation.gov for a $2 processing fee.
- The Interior Department says the tailored approach protects safety and resources as access grows, while conservation groups warn of traffic jams, resource damage and strain on understaffed parks after 2025 workforce cuts.
