June To Mammoth Bike Trail

For the ultimate mountain bike work out, you can take a dirt road all the way from June to Mammoth (or vice versa).  This has been done, and it can be difficult in the deeper sand areas.  The trail is marked with the green Mammoth to June signs and is primarily used by OHV.  The trail goes from flat/sandy areas to climbing and then descent.  You can start out at the June Lake Junction and make your way through Hartley Spring, Obsidian Dome and out onto the Mammoth Scenic Loop.  You do have a bit more elevation gain going from June to Mammoth (since June is a few hundred feet lower than Mammoth), so make sure you grab a trail system map and plan out your route. It took us 5.5 hours and the trail was about 25 miles with 2,000 feet of elevation gain. All that said, this can be a fun adventure.
