Coming from the north on New World Gulch Trail #50
, keep straight as you near the bottom of the hill at the north end of the lake.
You'll pass a random outhouse in the middle of nowhere, so if you've gotta go, now's the time! Pull yer pants up and hop back on that bike. Keep riding and you'll go through a stream and up a steep hill (I certainly couldn't bike up, and even down was a little gnarly). From there the trail is really awesome until you hit the dirt road a mile or so ahead.
While on this trail, you'll get to ride some really fun hills and quality trail. While there may not be any views of the lake and mountains, you won't notice. The trail is that darn good.
Once you hit the dirt road, pick the bugs out of your teeth, cause' you've been riding the whole trail with a huge grin. Seriously, you've got bugs in your teeth, take care of that...
