We just hiked this trail yesterday and loved it. Getting there would be my only concern in the future - we had an OHV and had no issue but I would not have taken a vehicle even with 4WD all the way to the trail head.

Other than that, beautiful hike, very secluded.

We hiked this trail on Sunday with our 12 year old son and 3 month old puppy. It’s really beautiful! It’s short but has several steeper sections. We felt it was pretty easy, but we ran into a number of people who were very winded - might be more of an intermediate trail in spite of the short distance, at least for people not used to hiking in the mountains. Be sure to bring water - we were surprised how many people didn’t have it.

The trees that were across the trail have been cut away. The trail is clear and easy to walk. Beautiful lake!

There were a lot of trees down covering the path, no big deal we found ways around it. The mudd is starting to dry up. Small patches of snow still. The incline right before the lake is pretty good, definitely doable an worth it. Around the lake there were a lot of boulders so it was hard for our dogs to climb but at one point our pup just got in and swan around to a flat spot. You are supposed to keep your dog on a leash and I would just remind people that this a good idea for multiple reasons. One being we did see Moose. It's a peaceful hike with very little traffic we only saw 2-3 people.

Trail was snow covered most of the way, starting out at about 12 inches, but usually about 4 inches. Many downed trees covering trail. Lake view at the end was nice, but with snow cover there was no obvious route to get other vantage points. The road getting there is a bit rough (gullies, snow) for the last half mile or so. Small AWD SUV had no troubles, but would have parked a bit earlier in a lesser vehicle.

Beautiful lake! The trailheads were misleading though and there are a couple different ways to get there. We took a trail off Highway 4 and almost missed it, it was so hidden. Our trek was almost 4 miles round trip and had more of an incline, but definitely worth it. :)

It such a beautiful trial and it's not that difficult. I didn't get to the lake because about 1.4 mails into the hike we actually did came in counter with a bear. Luckily enough we were a group of 7 and spot the Bear far enough where it didn't felt threaten and able to get away safely. Just be super careful and alert of your surroundings, i wouldn't go alone.

Good hike, although heavy traffic with people allowing dogs off leash more than expected. Fishing slow with lures

This trail was easy for us to complete. The climb was doable even for us not being acclimated to altitude. The drive up was beautiful and we saw moose. Then when we got to the trail, we saw a bigger one grazing. The lake was worth the walk. The mosquitos were really bad walking around the lake. Bug spray was a must. Overall we would highly recommend this trail.

Short hike, with a pretty lake at the end. Lots of good spots for lunch or a snack near the lake. We went early in the day during the week in June and there was only one other couple there. We did also see moose in the vicinity.

Really great trail, only a few switch backs. The view of Lost Lake is great on your descent to the lake. Watch out for grumpy fly fisherman. Bring bug repellant.
