My friend and I are planning to drive to Grand Canyon on the 16th of April, will the swimming pools be open and are they heated?

Both are open. Indoor room is heated with hot tub..outside is not heated but their outside hot tub is. We are here now and love it. Plenty of lounge chairs and huge pools

Do not stay in room 5219

We just stayed there last week. The indoor and outdoor pools were open. The indoor is heated. The outdoor pool is freezing. 😊
