You have a variety of hills and trials to take. We went for the harder hike this time to the top which was a nice view. I will do this again! Todd Ryan (256) about 1 month ago N/A: 21 Completed 5 Reviews This is a fun little hike. Not hard at all but not a walk in the park either. I would suggest taking lots of water and a hat because there is ZERO coverage. Wasn't crowded at all when I went. In fact I think I was the only person there. Jose Torres (102) about 1 month ago N/A: 1 Completed 1 Reviews Did this as my first hike alone and it was great! It wasn't too hard not easy, especially after coming back from a knee injury. Will def. be back to finish the whole thing Debbie Charles (137) 8 months ago N/A: 14 Completed 2 Reviews One of my favorite running spots!!! :) Michael Pierson (56) 11 months ago N/A: 1 Completed 1 Reviews I live a few blocks away from where the trail starts- or one of the many places the trail starts. Parts of this are incredibly challenging for both hikers and bikers- definitely not for young kids- but overall, a fantastic place. Is part of an extensive trail system running from Santiago Oaks, Irvine, and Wier Canyon Regional Parks. The system has trails for almost any skill level.

Marc Nitz (1424) about 1 year ago N/A: 40 Completed 20 Reviews Nice hiking and mountain biking trail. The initial biking uphill, when going counter-clockwise, is really tough and the downhill singletrack at the end is just like a downhill bobsled. Hard to beat! Inspire Educate-Motivate (239) over 1 year ago N/A: 8 Completed 3 Reviews nice hike. went Easter afternoon. very quiet. I would do it again but this time leave my tiny dog at home. I dont understand why people dont follow the leash law especially with bigger dogs. my tiny dog was attack but luckily I yanked him up like a yoyo. no harm but scary. Ted S (801) over 1 year ago N/A: 25 Completed 11 Reviews Fun hike that you'll moderately feel but won't take your whole day or even your whole morning. Some nice views of the Anaheim canyons but pretty much a dirt trail and hike just to hike. Kenneth Okumura over 1 year ago N/A: 249 Completed 27 Reviews Took me four trips before I felt I understood the whole trail system. Many different access points and options for extending the hike, but without a good map and some hints from John McKinney in his Hike OC book it could be confusing to people who are unfamiliar with the area. Still I thought it was a nice surprise! Depending on where you enter it you can be surrounded by residential development, but then suddenly the area opens up and it seems like you could be miles from civilization. I did the simple loop taking in Robber's Roost the first time. 6.0 out of 10.
