Getting There

Most of the hike to De Leo Wall in Cougar Mountain Regional Wildland Park is easy, with a couple of tough climbing sections. The trail is suprisingly remote given its proximity to civilization and the views from De Leo Wall through the tops of madrone trees are amazing. Cougar Mountains trail system is complex and although the trails are well signed, a map isnt a bad idea.

No permits needed, parking is free Restrooms and picnic table are at trailhead.

HikingGreat!Over grown

As others said, the middle section is very overgrown. What we ended up doing instead and worked out very well for us was, skipping middle section to the viewpoint, then taking a right towards the viewpoint at the "Split in the De Leo Wall Trail". It was a much more interesting and enjoyable hike with that modification. Not muddy with how dry it's been.

Pretty easy loop, but the middle part is very overgrown. Would definitely recommend long pants or otherwise doing the Wildside part as an out and back. View is okay. Not very crowded even midday Saturday.

Impressively monotonous, there were few outstanding features to make this particular hike stand out. At least I felt safe on the trail?

Good solid hike. Easy to miss the turn off for the viewpoint. The trail is narrow and marked only with a short white marker about 15ft off the trail. Definitely worth going to the viewpoint. More worth it is to not double-back and to take the trail along the edge to the north. Better viewpoints along that route.

Solid hike. Had lots of shade with spurts of sun. Muddy in areas to be expected, fine with hiking shoes. Tried out my backpacking pack while hiking, and went really well. Not hard but not flat, good elevation gain for a casual hike.

Perfect trail for a quick post-workday hike. Not too crowded, part of a larger park/trail system. Trail was not marked super clearly, as other folks mentioned, however if you just know the trail names (which you can see on the map) it’s pretty easy to follow/figure out.

Very pretty hike in the trees, not challenging at all. However, trail signs are marked very poorly. Barely saw anyone on the trail today, very calm and peaceful hike!

Followed the AllTrails map/recording for the De Leo Wall lookout and based on the recording, I crossed into private property, so just be considerate. I realized later that I could have taken the Viewpoint Trail, which I'm assuming is still within the county trail system for Cougar Mountain.

The trails were great. A little muddy. But a beautiful day. I’ve been visiting thus trail for about four years, so it’s become very special. On a clear day you can see Rainier :) i learned this area has been approved for clear cut logging straight through the park including trails, two streams, and the viewpoint. This will impact many wildlife systems and potentially create ecological hazards. There is a city hall meeting 1/21 at 7 in Newcastle. PLease come be of service to support our parks and remaining wilderness. https://www.savedeleowall.org

Great hike for a forest view. Trail seemed poorly marked and almost got lost; the trail splits a few different times & I didn't download the map first. my dogs had a great time. Not too many fall colors to see but quiet on the trail.

August 2019. Last reviewer said there was a hornets nest. We did not run across one. The view is impeded this time of year due to the deciduous trees in leaf. If you are looking for a view, it is best to hike after the leaves are down in late fall or early spring. It is a good workout regardless if you keep a steady, quick pace. Sidenote, if you lose the trail in a stand of evergreens about 1/3 of the way, look right and you will see the trail to pick back up.

August 2019. Bald host hornet were had some nest near southern trail. They swarmed my friends dog and got another friend. Keep an eye out for their nest/swarms. Otherwise it was a beautiful hike, well kept trails and wildflowers in bloom. Just have a map, i save my all trial mapd, and follow trail signs. Sadly as normal nature is a great reminder that its her home we in.
