This is an out and back trail with mild elevation gain that takes you through interesting landscapes, including rainforest-like vegetation, rocky fields, dry open areas and the Skagit River. About halfway down, the trail leads along the top of a gorge, from which you can look down at the turquoise waters of Lake Diablo. At the end of the trail the Ross Dam is visible. This trail does not have the most beautiful views of any hike in the area, but the varied vegetation keeps things interesting.

We got off the trail and ended up on a road that ended at Buster Brown Campground. Beautiful day and nice hike.

This is a really good trail to do in between harder hikes you may have planned for the North Cascades area. It was quiet, the trail was well maintained, there's not that much elevation gain, etc. If you want a good view of the lake, the lookout will be more ideal. But we did this trail on our last day in the park and at that point we had already spent a decent amount of time already staring at Diablo Lake from the lookout.

The view at the top was very disappointing! It is also very tricky to get on to the right path for the trail! But overall it was a pretty decent hike! Once you get to the top you can either go down through the normal trail or choose the other path that will lead you down to the water and you can pay a ferry ($10 per person/only cash) to take you back to the parking lot.

If you want the iconic view you have to drive to the lookout. You’ll see some patches of the lake between the trees on this trail. Beautiful but disappointed we had to drive to ultimately get the best view

Really beautiful trail! It’s easy to miss the beautiful look out and walk to dam but whole thing is amazing and fairly flat trail!

Loved! The water is freezing, but still refreshing after the hike. If you have a kayak, definitely bring it! The parking area is right on the lake.

Save yourself the time, drive hwy 20 and visit the overlooks. The views from the road are way better. Didn't get to see much on this hike. The few times there was an opening in the trees, the natural landscape was marred by power lines or dams. I was very disappointed.

Very unimpressed with the outcome of this trail. If you want good views of Diablo Lake, go to the Overlook it is much better than anything on this trail. You see Diablo in the distance through the trees, and the views are nice for a couple miles, but the trail abruptly ends at the end of a bridge next to a gravel road. My group and I were very disappointed, would recommend against it.

We did this hike yesterday, 7/9. I agree that the trail does have some pretty views about 2.5 miles in, but the end of the trail is pretty disappointing as it’s just a view of Diablo Dam. The trail is mostly shaded, and the trees, ferns, and moss are beautiful to look at, but I would recommend looking for a different trail if you want an overlook of the lake.

I’m with you Robert, Jess, I think you may have gotten this confused with Diablo Lake in CA, thankfully we didn’t see any rattlers on the trail today! However, we did come in contact with a sow and her cub down a sag on our descent! We also saw multiple deer which were absolutely stunning, even a pure white doe with babies! We loved the conditions of this trail and found it lovely passing through the coniferous forests, and over the rocky terrain, especially with stunning blue Lake Diablo peeking through the majority of the way. However, we were rather disappointed with the end of the hike at the dam. We were looking for a more climatic viewpoint, however, the views about 2.5 miles in are truly astonishing and well worth the hike in our opinion. Cheers!

If you want a nice walk in the woods, it’s a well maintained trail. If you’re looking for views, this trail offered very few. We didn’t have good weather but still, there didn’t seem to be a good payoff.

Sorry Jess don't buy your rattlesnakes comment AT ALL!

Got lost 5 times and it was hard to find the trail at first. The view at the end wasn’t much of a view at all. Overall the path was very easy even tho this hike ended up being 11 miles after we came back. Seen a few rattlesnakes on the trail
