An absolute gem of a trail that sees little traffic. Consists of incredible slabs - harder then hueso, boney elbows.
First climb up is a challenge, but can be ridden without dabbing.

1/2 way down the left hand line is recommended. The right hand line is a massive slab - sounds fun, but the consequences are massive.

Ending recently got some work, and is now much better.

Trail is in a serious state of disrepair. Could use a lot of love before it is worth riding again

Not ridden very much and it shows. Other than the top three variations the rest of the trail is starting to fall a bit into disrepair.

      It's actually a trifecta of the infamous Value Added, Penthouse, and Larvicide.

      i can do some decently impressive stuff on a bike, for example Chossys, value added, that stuff.

      But this

      No thank you.

      Definitely the hardest trail in the Alice lake zone, arguably the hardest legal trail in Squamish, in my opinion treasure trail is scarier and more committing but larvicide is definitely harder and requires more control and comfort to clean.

      One of the best. Old school gnarly slabs! Less grippy than the other slabs of the highlands.

      We hope you've been enjoying Trailforks!
