Ironman 70.3 will once again be held here in southern Utah. Sand Hollow is pleased to be the location for the swim. Due to this event the main boat ramp and ALL parking leading to and at the main boat ramp will be closed to normal park traffic. The south boat ramp and south portion of the lake will be open for regular day use traffic. Expect delays at the entrance until after 12:00 PM. We recommend for boaters and other water users to go to Quail or Gunlock that morning.
