Take this trail up the fork (about .75mi), then take a right onto Moonshine Gulch Trail #438
New World is awful for the next two miles or so, and Moonshine Gulch Trail will take you around that, and meet back up with it, right at the base of Mt Ellis.
Take a moment to reflect on how you just avoided the worst trail ever made.
Pat yourself on the back, maybe think 'That guy on MTB Project really saved my butt there. I should buy him a beer'. Yeah, you probably should. Thanks!
At some point, continue biking. The trail can get a bit wet, but overall it's 1000% times better than New World Gulch on its best day. You'll have some fire road, some amazing singletrack and some really fun hills all the way out to the lake.
On the way back, you might be tired, but put in a little more vertical and take the Moonshine Gulch Trail back as well. You won't regret it.
Watch for hunters and bears.
