Sand Bar Flat to Spring Gap is a three mile one way (six mile round trip) hike beginning at the Sand Bar Flat campground on the Middle Fork Stanislaus and ending at the Spring Gap Powerhouse. The trail parallels the river the entire length so elevation gain is at a minimum with only 277 ft in altitude gain. The max altitude is just under 3000 feet. This short hike can be turned into a longer six mile one way if you continue on past the Spring Gap Powerhouse to Beardsley Reservoir. This is a good year-round hike but may get a little busy during the summer season. Spring is a nice time since the foliage is still lush and green and all the little creeks are flowing at their maximum.
Access to this trailhead is seasonal and usually closes from November to April. Your best bet is to contact the Mi-Wok Ranger District for current road conditions. To reach the trailhead at Sand Bar Flat Campground take Hwy 108 east from Sonora and turn left on Fraser Flat Rd (Forest Road 4N01) a few miles before Pinecrest. Once you pass the Fraser Flat Campground the road turns to dirt. Continue on 4N01 for for several miles and make a sharp right on 4N88 just before the Crandall OHV parking area. Continue on 4N88 to Sand Bar Flat Campground and park in the day use area parking spaces. One word of caution, Forest Road 4N88 down to Sand Bar Flat is steep and winding and is not advisable for large RVs and trailers, most 2wd vehicles will not have a problem however. There is potable water and vault toilets at the campground.
