Stayed there 2 nights the last week of February. A beautiful area, and suggest camping there any season. Winter camping had the only water source in the men's bathroom. Dump station open for dumping but needed to use the fresh water tank  to rinse using the outside shower hose.

There is so much to see there, but a lot of ice. The trails were good in most areas, but as you descend in the gorge areas it becomes ice covered. I would not go without ice cleats for the hiking boots.

There were only a few other campers there. Would try for a site further from the water treatment plant (adjacent to the pool) due to the sound of the motors running.
