Hot Well Dunes is a strange and memorable desert outing: 2,000 acres of sand dunes open to off-highway vehicles, with hot spring tubs set in the same bare landscape. The sand is the remnant of an ancient lake shore, which helps explain why it feels so out of place.
It is best for travellers who like rougher recreation. Bring supplies, check road conditions, and expect a simple public-lands site rather than a spa.
