In the agency’s own words
var $j = jQuery;$j.noConflict();$j(window).load(function() {$j('#slider').nivoSlider( {effect: 'fade',startSlide: 0,animSpeed: 750,pauseTime: 8000});}); Boulder Flat Campground is situated in a mixed conifer forest along the banks of the Stanislaus River. It is located 20 miles east of the Summit Ranger Station on Highway 108. There are a total of 20 camping sites; one is a double site and two are walk-in sites. The main road is paved with dirt-surfaced parking pads. Restrooms are vault toilets. Water is piped; each hydrant serves several sites. A fee is charged for extra vehicle parking. There is no designated trail down to the river.

Nothing to book, just show up
One of 1,623 federal campgrounds where the site still goes to whoever pulls in first. Get there before noon on a summer weekend.
recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.
