The Flying Dog trail is a fun trail that arcs between the middle of 24-7 over to the top of the Cobblestone Loop above Glenwild . In other words, you need to climb another trail to get to it. This is one of the best trails in the area. If you're going to do anything in the Jeremy Ranch area, you need to do this one.
The trail instructions below include the 10-mile easier ride, a 16-mile moderate ride, and a tough 23-mile grinfest with 3000 feet of climbing. And you can add a dip down the Bobs Basin DH trails while you're passing by. There are a lot of great options here.
As the trail climbs, the oak gets bigger, then a few maples join in. As you climb higher and hit the north-facing slopes, you enter aspen forest, with a fir here and there. Throughout the ride, there's an assortment of open brush slopes, meadows, views, and forest.
A much-overlooked option is to start by climbing Graduate and Fink Again, then proceed to Flying Dog. After whatever short or long ride you chose to do, head down one of the DH freeride trails. If you've got anything left, keep circling back up until you've gotten your fill. Ant Farm, Team Cutthroat, and Dropout are great downhill-only routes with a lot of fun stuff. (These trails are described on the Jeremy Ranch 24-7 trail page .) But you don't need to be an expert to ride them. Just go around the stuff that scares you.
Jeremy Ranch 24-7: Just after Parley's Summit, take the Jeremy Ranch exit and turn north (left) under the freeway. Turn left at the first stop sign, then take the next right (Jeremy Ranch Drive). Continue until the road turns sharply around to the right, where you'll see the dirt East Canyon Road branching off to the left. Park and climb the ST on the east side of the road (the direction your car was facing as you came around the paved turn).
Jeremy Ranch, Graduate trailhead: At the I-80 Park City exit, go north (left from the exit if you're coming from SLC) to the frontage road. Turn left on the frontage road. Next turn left again toward the school. As you pass the school, there's parking on the left. Just past the school, there's a fenced area with a shed on the right, and a gravel roadway on the far side. About 100 yards down this gravel path, at the end of a broad gravel area (don't park here), there's a wooden bridge. That's your trail. At the first fork, keep R. At the 2nd fork (Fink Again), go L.
