Loved the area. Took my 7 year old son on a Saturday morning "adventure".
Solitude was great, we did not meet a soul on the 3 hour hike. Saw lots of deer, fish (on the trail next to the river) and quite a few Bobcat tracks (following one of the trails)
Negative: lots of trash in form of empty plastic water bottles. Graffiti at the overhanging cliffs.
Most positive: my son asked me if we can come back and pick up trash !
