I looked online and thought about making a reservation in advance, but wasn't sure about where I would end up by the end of this day in my trip. I stopped at noon and asked if they had any 30 Amp sites, but no, dry camping only. As this is in an area of BLM land, it should not have been difficult to boondock in the area.  This place has water available, showers, clean bathrooms and of course the hot springs.

The check-in time is 3PM and if you arrive early, you have to leave and come back at 3 or pay an extra $10 per person (on top of $35 for dry camping) for early check-in. This rule might not be enforced by all staff members. You also have the option of paying a day use fee of $10 for 4 hours or $5 if you are 62 or older. Once again, being old pays off and I paid the day use fee to stay around. The hot springs pond is well developed and temperatures are regulated well. 

The WiFi had problems and I was told that I may need to remove the settings for the site a few times to make it work. When it was working it is mostly just close to the office, but there are picnic tables near the hot springs and it is a pleasant place to work.

I would stay here again, but book in advance to get an electrical connection.  It is also worth stopping for a few hours in the day to use the hot springs on a day use fee.
