Connects Mid Mountain to bottom of Silver Star restaurant, rest rooms. Good exit point to end ride from Silver Lake Lodge via Mid Mountain trail.

Good alternate to get to Shadow Lake area or up to Scott’s area/Puke hill access. It is “direct” at a grade that’s steep, but not terrible. Some loose rock, occasionally a downed tree, but it’s not busy and is a good way to mix things up to/from upper mountain once in a while.

As of today, there were 7 dead aspens blocking the trail going east towards CMG. none of them were rideable, so had to shoulder the bike and climb over. Hoping someone with more lumberjack experience than I do can get out there soon and remove them.

You can technically go up it, but just don’t. Nobody does except lost people on rental bikes. Armstrong is uphill only and goes to the same area.

As straight up climbs go, this one is as nice as you’ll find. The grade isn’t bad and mostly shade, but if you’re coming from sea level, you’re probably going to sucking air all the way up. Stay hydrated too.

I know this trail is very popular, but I did it a couple of days ago and it was not very fun. It was a serious washboard. Even the berms. Kind of disappointed. Hopefully it gets some TLC.

It's one the classic Park City trails, everyone's ridden it. But for a 1500 foot descent it's pretty boring. Buff, straight, not much in the way of natural or man made features or flow. You're still going to end up on it.
