Best Time to Camp at Twelve Mile Flat
Summer at Twelve Mile Flat brings a delightful contradiction – sun-warmed days perfect for hiking and exploring, followed by crisp mountain nights that remind you just how high you've climbed. Even in June, temperatures can plummet into the 20s after sunset, making that campfire feel especially welcoming. Afternoon thunderstorms roll across the plateau with dramatic flair, occasionally bringing hail and gusty winds that bend the pines. On those perfect summer weeks, you'll enjoy comfortable daytime temperatures hovering between 47°F and 68°F – ideal weather for mountain adventures.
Open June–Sept; reviewers praise wildflowers, warm days and crisp nights in summer.
Fall foliage and late-season access (FCFS into Nov) receive positive mentions.
Campground opens mid-June; spring season not in main operating window.
Campground closed for winter; limited winter access noted.
