Beautiful hike, very peaceful. No running water in the summer time though! Or at least this year.

Very quite the morning after Fourth of July. Beautiful woods to wander through. Dog loved it.

Wonderful hike that’s got a decent amount of flora and fauna to enjoy. Not many views from the loop however.

Last weekend my golden retriever pup and I enjoyed this trail.

nice trail but can be lost in there without a GPS.

6/11/2018 (Monday) - My loop is much larger than the "official" one. I start from Red Town, out via Wildside, Quarry, Fred's, to Wilderness Peak. The signing book is no longer available from last time (2 months ago). Then, go be the level Fred's, Klondike Swamp, Lost Beagle up to the 2nd peak, the radio tower on the former AA Peak, where I have lunch, then I move down via Lost Beagle, Coyote Creek, Cave Hole back to Red Town. The loop is 8 miles, takes me 4 hours. All trails are in good condition.

We enjoyed this hike. Gorgeous terrain. Many teens and an oasis just past a residential area in Renton. Who knew!?

5/19/2018 (Saturday) -- I added this route and AllTrails approved it. It seems that most Red Town users may not take Military Road Trail up to Sky Country, and then down to Coal Creek Falls. This is loop of about 2 hours' walk that requires more efforts than those most popular trails with moderate elevation gains (more than 700 ft), so it should be considered as an ideal workout for less energetic but active hikers.

5/13/2018 (Sunday) - 9:15-12:30, 65-75F, sunny, not hot in the woods. Up via Big Tree Ridge, Red Cedars, No Name, Bear Ridge, Tibbetts Creek, Tibbetts Marsh, Lost Beagle to the peak radio tower. Lunch with picnic table. Down via Shangri La, Surprise Creek, Precipice Top, Military Ridge, passing Harvey Manning Park, straight down via an unmaintained old and nice trail (very rarely used) to Newport Way TH. Busy Mother's Day, all parking lots are full. Lots of family groups. Trails are dry, very well-drainage.

Nice hike on a sunny morning

5/8/2018 (Monday) -- The trailhead for this loop with light traffic is at the cul-de-sac of 171st Ave SE. The trails are well maintained with good drainage, so there is almost no mud at all, why the creeks are still running, and the falls have not become dry yet. Leaves have mostly grown out, so shade is there for a sunny day. In the woods, temperature is 5-10 degrees cooler than in the open areas.

Easy hike. We took whole family, kids and family members of all ages. Views are of forest and trees thought we might see a bit more of the area. We did stick to main loop. Maybe next time we will go off main trail to see if views change.

The hike itself is ok, but as others have mentioned, the “view” is underwhelming and does not make for much of a destination. Opt for the Big Tree Ridge Trail instead if you want a truly stunning view from Cougar Mountain. Also, the only moderate section of this trail is the somewhat steep decline to the so called lookout. This can easily be bypassed by continuing down the main trail and then traversing .1 mile to the lookout. Traverse back and finish the loop.

Hiked this recently on a trip to Seattle. This trail was amazing! And I loved seeing all the dogs on the trails.

A very nice easy trail system that is nicely marked. It's a nice area and will definitely keep going back.

Well maintained easy to moderate hike. The waterfalls were nice.

Good running trail as the elevation gain is minimal for a hike but not a whole lot to see on the way. Moderate but persistent grade; there is more interesting terrain on the Anti-aircraft ridge trail and some cool logs you can jump over on your way up or down the mountain. There’s an okay view at the beginning of the trailhead of Lake Sammamish but there’s not much space to enjoy it.

really nice forest trail.

Good hike, worth doing, bit really not much to see other than woods... the waterfall is nice. Lots of access and short cut paths to make the hike shorter or longer.

I am not sure why this wouldn’t get more 5 stars. It’s appropriately rated, easy to get to, trial is nice, and there are many many smaller trails to make it more challenging or longer. I went to both waterfalls, the first set is about .5 miles from the cul de sac, and cascade waterfalls are 1.0 in but another .5 uphill to get to. Very little mud, very few hikers (2pm on a Thursday till 5pm). I had a small dog and a baby strapped to my front and was comfortable the whole time.

Well marked, relatively easy hike. Moderate traffic, saw about 15 people.

Excellent hike with some trail running on the easier sections. I added the Whitaker Wilderness Peak to Wilderness Creek loop that made it 8 miles and 2500 feet elevation gain. It was a good workout.

Nice calm trail wiith a beautiful waterfall view

Perfect easy trail for a wet afternoon.

I couldn't neccessarily find the De Leo Wall trail because tho it was marked on the map, there was no "you are here" point. Also, none of the trails were marked De Leo Wall.
However, this was a fun little hub of interconnected trails.

Great trail. Lots of different side trails to choose from. Far Country Falls was amazing to see

Went over the summer, and the hike was eclipsed by how buggy it was. Very pretty, though.

Great for the family or by yourself. Good views and leisurely hike. Make it more of a challenge by running it.
