Views, off trail bushwhack, Lovely San Jacinto State Park This trail is up and down, up and down. It is very hard to get a rhythm going as you are constantly changing pace. The trail is much easier going in, than coming back out and some of the final ups and downs can be very painful. Make sure you are in good shape for this one. The signed distance to San Jacinto Peak is 8 miles from the trailhead, it feels a little further, and I would suggest visiting the highest point in the park as well, making this a 17 mile round trip - it feels much longer, and it takes all day. We left a 7 AM, after getting a permit and driving up Black Mtn. Road got started on the trail at 10 AM, we were back by sunset at 7:30 PM. There is no trail to Jean Peak, you must make your way boulder hopping and bushwhacking through Scrub Oak. It is pretty easy going though, and getting to the top is simple. Finding your way back is also easy, just head for the highest point.
