This trail is open to motorcycles from 5/1 to 11/30. Look at the USFS SNRA MVU map.

Fantastic trail, scenery was breathtaking. i did this as part of loop. Up Boundry Creek, down Big Casino, then up little Casino and back down Boundry Creek 32 mile loop open to Dirt Bikes. It has it all tight rocky section as well as fast really flowing sections. Well maintained

Total ass kicker of a climb but sweet views of the Sawtooths. Never actually insanely steep just pretty relentless

Watch out for the downed tree about a third or half way down. I came flying around a corner and had to slam on the brakes to stop myself getting decapitated by the neck high tree blocking the trail. It was close. Fortunately I got it on camera, so it was definitely worth it.

Fairly featureless speed trail. Could almost be considered a green, just nothing technical or really fun to speak of. Wouldn’t recommend to advanced all mountain/enduro riders, very XC

Road Fischer/Williams May 16,2020. North aspects still covered with snow. Hiked the bike more than rode our bikes. Cleared many a down trees. Probably a few more weeks of sun and it’ll be good to go????????!

Not an easy trail. Seriously torn up by mottos in some places. Several parts unrideable. Some sections oh so good. From boundary to Williams it's almost flat then dumps into the burn part. Glad I did it but not sure if I would again.

Super loose kitty litter and moon dust with giant ruts from motorcycles. Very steep in places resulted in quite a few hike a bike sections especially just prior to Boundary Creek intersection. I would not ride this trail ever again. Should be removed from MTB maps in my opinion.
