like she said it's a poison oak riddled workout. But on the up side if you make it down you are rewarded with a number of fire rings.
It looks like some older generation used to come here to party on the weekends when they were younger. Kids these days are too lazy to make this climb.
If you persist upstream you will find a beautiful place to rest and swim. Pools deep enough to dive in and a peace you can only find in solitude.
This trial begins on a steep uphill climb, and there is poison oak everywhere. Once you reach the top of the ridge, you begin to climb down several switchback on what seems to be a neverending descent to the river. I saw a lot of scat along the trail, and was well aware of the bear sightings in the area. Overall, there are better trails that lead to the same area of the river, and they are all a lot better. This hike is for sure a workout, and the cool pavement of the road offers a nice place to rest and catch your breath when you make it back. =.=
