Located in the "Issaquah Alps," Cougar Mountain showcases a variety of natural features from forests and waterfalls to meadows and cliffs. Sweeping vistas of the Cascades, Lake Sammamish, and Bellevue, Seattle and beyond can found at different points throughout the park. Rather than a single "anti-aircraft" trail, there is a group of trails and loop options that begin at the Anti-Aircraft peak trailhead, including ant-aircraft ridge.

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.

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

Very well maintained and signposted trails, but doublecheck your maps at each one. We had three on us and still made a wrong turn to add a mile. Great for kids and older folks, nothing too challenging.

The trail is closed just after the bear ridge turn off. Was a bit disappointed, but made the best of it.

This is a really pretty walk but as expected, still a little muddy. We took the trail as far as we could before having to double back to the 'No name' trail. We eventually met up with the 'Surprise creek' trail and back to Shangrila. For the first 'hike' of the year, it kicked my butt. As a 240lb guy, the uphill from the park boundary up to the 'No-name trail' was the most severe incline. Probably a nice, mellow walk in June/July.

Well marked trails did the AA loop about three miles. Good workout!

nice fast and flowy for all you runners out there, but easy grade that is really made for walking not hiking. Nothing too technical, but beautiful forest to enjoy on the fly.
And the drive in is straight bonkers and worth the trip alone.
short trails that connect make for a good day training.

Went on my first trail run here. The trails are a little muddy right now, but otherwise well maintained. This trail head has a nice parking area, and on a clear day, views of the water.

This is a pretty easy trail. Grab a map at the trail head, it'll help you choose which trails you want to take and how to get back out. Good for trail running, dog friendly, as well as kid friendly. Well maintained and very little water flow during this time of year.

Not too many people. Lots of different trails to choose from. Good beginners hike. The only good view that I could find was right in front of the parking lot where the picnic area is.

Very easy hike and close to city. Quite a few narrow one person paths.

Our third visit to CMRWP, and we're no less enamored of the park than before. Big rains overnight, and really, only a couple of spots on Shangri La west of the trailhead were tenuous. Still lovely - sad that folks are "bored" by the area - and we'll continue to explore this nice, close-in venue. The others we encounter are always friendly, and understand 'sharing' the trail.

Is a pleasant hike. Not much to speak of during the hike, a tad boring and unchallenging for myself, but the view at the top is spectacular. I enjoyed the historical stuff at the top as well. Probably a good trail for families, those who are out of shape, or looking for a relaxed walk up a mountain, but nothing to challenge your self with.

This place is close, easy to get to and seems like it is in your backyard. The hike is easy and was not very crowded the day we went. The view of Lake Sammamish was a nice payoff.

A walk in the woods close to the eastside cities. Most of the uphill is done in the car when you drive to the AA trailhead. This is really a group of trails starting at the Anti-Aircraft peak trailhead rather than a single "Anti-Aircraft trail". Some peekaboo views of Lake Sammamish and beyond are available, including a fantastic view today of Mt. Baker. The fantastic erratic was a nice stopping point, but not exactly fantastic.

nice hike! my 4 yr old loved it. we found "fantastic erratic" and it is fantastically erratic the way it winds around down the mountain.

Too easy, kinda boring. No features except for a limited view of Lake Samammish. Went in July and the flies were everywhere and were biting like crazy.

Great trail with lots of trail choices. Good geo-caching options as well. Took two 11 year olds and hiked for three hours with no complaints!
