Best Time To Visit Grand Canyon

Mar–May · Sep–Oct

The clearest window for a rim trip — mild days in the 60s and crowds still short of their summer peak. The North Rim reopens for day use around mid-May, so a late-spring visit can take in both rims. South Rim campsites and lodges book out for these months, so reserve early.

What's open: South Rim, the Rim Trail, and the free shuttle run year-round; the North Rim reopens for day use around mid-May (no in-park lodging there in 2026).

Jun–Aug

The rim itself stays comfortable — highs in the low 80s — and summer is the one season every viewpoint, lodge, and ranger program is running. It is also the most crowded stretch of the year, so reserve lodging months ahead.

What's open: Full service on both rims; arrive before 9 a.m. or ride the shuttle — the lots fill by mid-morning.

Apr–May · Sep–Oct

If your trip is about hiking into the canyon rather than seeing it from the top, go in spring or fall. The inner canyon runs far hotter than the rim — past 100°F at the river and 109°F in the shade in July and August, when the Park Service warns against hiking below the rim between 10 a.m. and 4 p.m. An overnight at Bright Angel or Phantom Ranch needs a permit booked months ahead.

What's open: Bright Angel and South Kaibab trails are open year-round; their seasonal water stations run spring through fall.

Jan–Feb · Nov–Dec

The South Rim stays open and nearly empty — snow on the rim, crisp clear views, and the lowest rates of the year. Rim trails ice over, so bring traction devices and treat this as a season for the viewpoints and photography rather than a big descent.

What's open: South Rim open all winter (expect snow and ice); the North Rim is closed until mid-May.
