Probably best to avoid in summer. The weather is really hot and, being in the desert virtually no shade. The lake is fun to swim in and the water is clean. Zion is within an hour drive. We stayed a few night in September and as soon as the sun set an incredible amount of gnats would come out making it impossible to keep any headlamps/lights on. The bathrooms were clean and the views were great but the gnats were definitely annoying. Winter would probably be better.
