If you have even a tinc of patella-femoral issues, it might be good to sit this one out - a lot of up/down. That said, it's all sublime. My son and I made a point to stop and take things in - as a 4th-grader, he was a bit disappointed by the lack of devils, but got over that pretty smoothly. Can't beat the vistas and knowing that Eugene O'Neill probably hiked at least a portion of the same trails back in the day. Highly recommended, but bring plenty of water - you'll need it with some of those fire roads at the end.

I brought over 40 oz of water and it wasn't enough (it was in the 80's) but luckily there were water fountains at the top. The first couple miles of this hike are a breeze but it gets significantly hard/steeper for the next few miles. I run regularly but was still very sore the next day. It was a fun hike but not as easy as some other trails rated 'moderate' on this app.

Awesome, varied trail with some excellent sweeping views of the bay area. Doing the whole loop in 90+ degree weather is certainly a challenge for the less experienced hikers. Bring plenty of water and prepare to be handsomely rewarded for the endeavor with a visual feast of nature and wildlife.

We started from Juniper camp ground. It's hard and no shade at all. There are a lot of gravel which makes it tough will climbing down.

Awesome for a weekend hike. Took a few hours, was definitely a little difficult but a great hike!
