Great place for a picnic, short hike, or afternoon chill session. Lots of tables, some shelters, about 2 miles of trails.
There is seasonal camping, probably great for tents, separate area. RVs might be used to higher standards; very few level sites with elec and water, very little vegetation separating sites.
NO FEE for day use, at least this time of year. BTW there aren't stores nearby, so plan accordingly.
