About this campground
Tucked away in the heart of Sawtooth National Forest, Mill Flat Campground offers an intimate escape with just seven thoughtfully spaced campsites. This hidden gem welcomes both RV enthusiasts and tent campers to its serene open canyon setting, where the absence of fees and crowds creates a refreshingly authentic outdoor experience. From June through October, adventurers can claim their spot on a first-come, first-served basis, making spontaneous getaways delightfully simple.
The campground offers basic accommodations including tent and trailer camping. The lack of potable water and other modern conveniences indicates a more primitive camping experience.
Weather and SeasonsSummer transforms Mill Flat into a sun-drenched haven, where warm days invite endless exploration and cool evenings are perfect for stargazing around the campfire. The dry conditions create ideal camping weather from June through early fall. As autumn approaches, crisp mornings hint at the transformation ahead, when winter blankets the Sawtooth region in snow and temperatures plunge below freezing. Smart campers plan their visits during the golden window of summer and early fall, when nature shows off her most hospitable side.
