You can cycle down to the Ranger Station for free and there is a bike rack to leave your bike while you explore the area. If you're not up to cycling back up the hill towards Mammoth Lakes you can pay to ride the shuttle back up if there is room. Keep in mind that the road down is steep and narrow, uphill traffic has the right of way, and the 15 mph speed limits applies to bikes as well as motor vehicles.

The Devils Postpile National Monument, which is only open from mid-June to mid-October, was once part of the Yosemite National Park and was only placed under protection as an independent park in 1911. The main attraction of the park is Devils Postpile, an approximately 100 meters wide and 30 meters high cliff of vertical, volcanic basalt columns, which have a very symmetrical, hexagonal shape.

Minaret Falls Campground has a beautiful setting along the upper Middle Fork of the San Joaquin River. Nearby, Minaret Creek cascades into the river. The campground has 27 sites for RVs, trailers, and tents. All the sites are $23 first come, first served and cannot be reserved in advance but fill quickly in summer. Fishing is good in the river and lakes. Horseback riding can be arranged at Red's Meadow. Devils Postpile is only 2 miles walk away and other hiking trails head out in several directions. The PCT is across the river at the falls. A narrow access road leads to Minaret Falls Campground. While camping here drivers may bypass the Reds Meadow Shuttle Bus, but are still required to pay a $10 entrance fee. The shuttle only operates in summer. https://www.fs.usda.gov/recarea/inyo/recarea/?recid=20514

Most hikers begin just the short hike to the spectacular Rainbow Falls from here. But past that turnoff the trail continues along Fish and Crater Creeks to the idyllic remote Iva Bells hot springs. For overnight hikes into the wilderness a permit is required.
