A nice hike in the woods with an overview of Diablo lake at the end - however when I did the hike this afternoon (8/20) there was so much haze that you couldn’t see much of a view.

My 5 stars are for the trail and spectacular views, but I agree with a previous reviewer that this is not an easy trail for everyone. I am a very fit 70-year-old and found it quite a challenge. It took me 2 hours to reach the summit and 30 min to come down.

Nice, simple and easy hike. Views of the lake are pretty but not as great as the lookout point just further down the highway. Trail head was tucked back in the campground so it gets a lot of traffic.

"Easy' may be relative and needs to be qualified. For families with small kids and elders this trail may pose some challenge depending on their physical abilities. Relative to an urban park trail which most people would consider "easy", this trail is a climb and rocky/uneven all the way through. The view is worth while but the "kid friendly" tag probably best applies to elementary-school-age kids and up. May be do-able with younger kids not on a carrier, but YMMV.

Easy hike with beautiful views at the top. Did see a large black bear on the way down close to the trailhead, ran off when it saw us.

The trail was pretty easy with great views of mountain peaks most of the way. The views of Diablo Lake are amazing. Definitely wear good, supportive shoes to make your life easier, lots of lose rocks that can make it tricky for someone older or not so graceful.
No complaints at all and will be back!

Simple hike. Don't let the creeks in the beginning stop you from this one. They aren't too difficult to cross especially with trekking poles.

Well maintained trail, nice stretch off the legs when traveling the North Cascades Highway. View from the top of Diablo lake is very good. the information sheet at the North cascade visitor center had the elevation gain at 425 feet, listed on all trails at just over 700, it feels more like the latter.

This is a very pretty trail with beautiful views of snowy peaks. It's fairly easy to do, and very kid friendly. The end of the trail is nothing special compared to what you see all along the way, Well worth a detour, especially if you have kids.

Great out and back trail leaving from the campground. Perfect for families with children 6 and up. Great views of the lakes and peaks along the way.

Well this trail is completely washed out as of may 5 2017. Water is too strong and deep to even attempt to cross. The surrounding area is serene enough though and I saw a grizzly bear near the trail head.

View of Diablo lake at top is awesome, easy hike a little elevation gain. my 11 year old & 70 year old mother nature law stopped half way up. I jogged up the rest with my husband so we could see the views.

I took my eleven year old son and my 3 year old lab. Perfect length and elevation gain for minimal complaining. :) beautiful view of the lake from the top. Well maintained trail.
