There are vault toilets accross the river, otherwise digging your own holes is your best alternative, no running water other than a river. If you have means to filter water, no problem. Trails are well maintained, beautiful hikes!
We stayed on site #3, nice and shady, perfect walking distance to clean vault toilets, water spigot not far, and off the road so you feel tucked away. Nice sturdy picnic tables, latern stand, and great fire ring with attached grill, and an additional freestanding grill available. Loved that spot!
