Great spot, central to Zion, an hour and a half from Bryce, and a hop skip from the AZ border. Need supplies? Hurricane and La Verkin are a few minutes away.
Went in July, monsoon season. It rained with thunder, lightning and wind everyday around 2pm until 6/7pm. And it was hot. Make sure to be ready for the heat with shade and plenty of fluids + salt supplements to keep your electrolytes in balance.
