Only had time for a few miles for our evening hike. We couldn't do the Hidden Lake trail we planned, as it is on private property, so we ended up here for s quick hike. It started off with the nice view of snow capped peaks (visible from the snowmobile path) but once on the trail the scenery didn't change much at all. It was nice to be in the forest and near the water but we had no views and only came across a small meadow.

Haven't even hiked it yet but the fact that fallen trees and washed out ground is present makes it so much more exciting!!!!

Very wet conditions. I'll post some photos. Great workout for my out-of-shape arse, and very technical. Even the 4WD road was tougher to ride than I expected. Gal in Jeep commented, "how the h*** are you doing this on a bike?!?!" Once I crossed the bridge to take the single track trail down, the first 1/4 to 1/2 mile was too tough for me to ride, and I think I'm decent with technical rides. Lots of on & offs. The rest of the downhill was great. I didn't see any other bikers, plenty of hikers. Wet / muddy conditions. If I did it again, I would ride the single trail out and back to avoid the 4WD road. I tracked this with a iPhone, so the GPS gets a little wonky. No cell service with AT&T or TMobile.

Great afternoon hike. Initial trail is a service road that runs along the river then you'll encounter a slight incline where you reach the summit overlooking the reservoir.

Thought I'd check it out, hoping it was open by now since I wanted to hike with my dog, and it is still closed. Wonder if it will be reopened eventually.

Absolutely beautiful scenery! Serenity abounds whether you're near the river, in the grassy plains area, or looking out over the lake...it's my favorite trail so far! Just make sure you keep an eye out for directions on trees and posts because there are some trickster side trails along the way.
