Doesnt look that green anymore, but a very nice hike. The hills look furry and wildlife was all around. Would most definately go back, mabye with a bike.

My husband and I hiked it this morning. It was sad to see so much of the vegetation burned from last years fire. I can imagine it being more shaded and beautiful if not for the fires. The only problem we had with the hike is that "Easy Street" is not marked, we took a chance and ended up taking the right trail. It is marked only by the word "trail and no bikes allowed". So other then the scenery burned and the trail not marked, I would definitely do this trail again. It took us 1 1/2 hour to finish.

I'm new to hiking and thought this trail was moderately challenging. The trail is not very well marked and the Easy Street portion of it is very overgrown. The scenery is beautiful, however! If going for a late afternoon hike, beware of the rattlesnakes. I didn't actually see any, but I saw at least 15 fresh snake tracks all along the north side of the trail. I saw several bobcat and mountain line tracks on that side as well.

I didnt exactly follow this trail, but you should know that most of the single track is severely overgrown. Makes for a fun day of bushwhacking, but also be careful, dont get lost. At 100 degrees, I was glad to have extra water and a map. Still not all trails are well marked. I could not find Easy Street at all. But I did see a Mountain Lion on Telegraph Canyon, between Little Canyon and Four Corners. A relatively small cat, ran away as soon as he heard me coming.

I live in this area and do it both ways. Clockwise is probably easier overall cuz once you get over the first hill its mostly downhill. Telegraph is an easy grade up and Easy Street is a short climb out of the canyon and puts you right at the Rim Crest entrance. When going clockwise, easy street does sneek up on you on your right and dives under trees and across a little stream. You can easily walk by it if you are talking and not expecting it. Good training loop for trail running. Watch for mtb bikes barrelling down descents.

The directions were WAY off base, just simply wrong. We hiked this trail today and got completely lost. We got as far as the Telegraph Canyon trail, went 2 more miles and further, and saw no sign for "Easy Street Trail." We saw Sycamore Trail and another trail marked only as "Trail" but no Easy Street. We kept going on Telegraph Canyon and then turnd around and got coompletely lost. Granted, I should have taken a complete park map but the hike was only 4 miles and I thought the directions would suffice. Needless to say, after 3 hours of wandering around, we called in the SB County Sheriffs Dept to pick us up. Embarassing, yes, but we were exhausted and had no water left. We took plenty for 2 hours but not 4 plus hours.

Hiked a portion of this yesterday afternoon. Started at the Rim Crest entrance and went up the south ridge trail, down Diemer trail and then hiked out to the main park entrance via telegraph canyon. It was nice, only saw three other people and only then when I was at the end of the trail. Kind of spooky hearing the gas flow through the gas line, took me a second to figure out where that sound was coming from. Got to see a couple of good sized coveys of quail flush from the trees. All in all, a nice afternoon hike.
