Trail Snake Pit
This is a good trail and riders shouldn't be intimidated by the name or grade, it is a blue. It looks like there's been some nice trail maintenance in an area that would take you too close to a gully. It's a fun ride and definitely better than the alternative route.

A good trail considering it was probably a hiking trail to start with, we need more of these in the area. I'm tired of smooth Park City, can we get some good cottonwood trails bill or will that never happen? The area seems to have awesome potential

Seems like maybe this trail has been widened a bit since I rode it back in 2020. Still though, major no-fall zone.

A bit punchy in both directions, but smooth in a crucial ascends. Traverse the Basin’s rocky slopes is epic. Critical areas are well maintained.

Incredible going down, predictable giving you plenty of time to pick the best line.
Going up is for masochists.

There is exposure but it isn’t as extreme as I was expecting based off the description. Fun, short trail

For uphill riders, right before crossing the Cecret Connector Road, stay left. I stayed right around some rocks and ended up on a "fake" trail after crossing the road.

Super fun trail, I wonder if it doesn’t get ridden much bc it’s short? It’s a bit loose a bit techy and a bit flowy, with awesome views. Not really a full on black, but there enough line choices to make it intermediate to lower advanced. To me it’s like the better parts of the crest

Coming down it's a great high country trail, lots of fun and not crazy technical. Coming up, it's a bit of a bear, steep and a couple hike-a-bike sections.

Super fun way down from the pass. Good line of site most of the place in order avoid hikers and others coming up.
