We stayed here 1 night and had the place to ourselves. It is a very large area and quite beautiful.
Not the nicest campground but not bad for $14. Some people were using tents but the ground is just rocks so wouldn't recommend it. It had 4 toilet blocks and water/ washing up station. It was quite empty when we stayed but suited are very close if full.
$40 for site with power and water, $35 without. $10 hot spring/pool entry per a person for camping guests. $2 per a person for 6 minute showers. Depending on how bad you need a shower there are showers in the pool area for a quick rinse before and after using the pool so you can save your $2. I would recommend the pools, they are awesome. Camp sites are pretty close together but all places seem to be around here.
