Little punchy to start bit fun overall. Love the steep exposed one side single track near the end. It really makes you keep your eye on the trail. No sightseeing on this trail. Great semi-tech trail that leads to the fun flow of Squid-line.

Quite good enjoy this trail as there’s lots of TTF without it being too rickety. Not too much peddling either, especially compared to Squid and Emma, both of which I’ve stopped riding as the lower sections are way too much peddling for too little reward.

This trail is a blast if you don’t mind roots, rocks and technical features. If you want fast and flowing, this isn’t for you, and there really aren’t any trails like that on Sumas Mtn.
The upper section is awesome, as you’re just cruising along on the softly padded forest floor. Some nice clean drops that are great for the intermediate rider - some real confidence builders. Looking forward to hitting it again!

I enjoyed this a lot. Rocks, roots, steeps, and some loam near the top. Little bit of pedaling required, not enough to dampen the mood, just a good technical descent.

Nice trail, good challenge. Some small climbs near the top, fairly mellow descending. Middle is steeper, very loose and technical, bordering on double black in spots. Made trickier with all the baby heads. Bottom is quite flat and flowy. Good fun all round. I'd ride this over knob gobler anyway.

No matter how hard I try I cannot bring myself to enjoy this trail. Next to no flow, one punchy climb after the next. Some fun little sections few and far between. Do not recommend. Go ride Time killer.

This trail was a blast to ride. Combined with Squidline, you get a wicked fun combo of tech-gnar followed by Mach chicken speed!

Yet another trail rated (quite poorly originally!) by my pocket... I haven't ridden down this trail (I've hiked up it recently though) for over a decade. Hikers have definitely wandered off the original line making it confusing at spot as others noticed. There's some steep awkward sections and tight corners, but I've ridden less enjoyable trails for what thats worth.

This is NOT a cycling trail. It is stunning hiking trail but not in the least bit rideable.

This trail is best left for hiking. The lake is a great view point and the steep terrain provides some good views. Actually surprised that this trail is even considered a mountain bike trail.

I rode Chadsey Lake for the first time today. Its a challenging trail, there are lots of roots and loose rocks. The section from the towers to the lake has some pretty steep sections but nothing too bad. The trail is severely braided in a lot of areas especially above and around the lake. It is hard to tell where the real trail is. Also there are a lot of spots where you have to get off your bike to climb over stuff. This trail is not really a good mountain bike ride. The moments when you are on your bike are pretty fun but you'd be better off on the other Sumas mountain trails.

The trail is quite dry but still riding really well. A few of the steeper corners have turned to fine dust, but still rideable.

The dirt was hero thanks to last night’s rain, but the overgrowth is hindering the trail now in a few key sections. The new wood is mint!! Thanks!
