Best Time to Camp at Diamond Lake
Summer arrives with brilliant blue skies and warm, dry days that invite endless outdoor pursuits, though wise campers stay alert to occasional wildfire smoke that can drift through the region. As autumn approaches, crisp mountain air gives way to winter's dramatic transformation, blanketing the landscape in pristine snow. During peak summer months, the lake's abundance brings clouds of mosquitoes at dusk—a small price to pay for paradise that seasoned visitors counter with proper preparation.
Peak season: abundant activities and great views, but high insects, crowds and facility issues noted.
Campground closes after peak season (off-season closure Sep 2–Jun 15).
Campground remains in off-season closure through spring months.
Campground is seasonally closed in winter; winter activities are regional but site is closed.

- Peak Season: June 13 - September 2, 2025.. Book 2-3 months ahead.
- Operating Season: Peak season: June 13 - September 2, 2025. Off-season closures from September 2, 2025 - June 15, 2026.
