Take a houseboat vacation to Warm Creek Bay on Lake Powell which is only a few miles from Wahweap Marina. Easy access to all the marina amenities, fuel and decent cell phone reception. There are a lot of sandy beaches and several excellent coves, depending on the water level, that allows for camping, hiking, boating, jet skiing in Warm Creek Bay.
The channel between Antelope Island and Castle Rock is known as Castle Rock Cut or pass. When the lake drops to about 3610 feet this pass ceases to exist and boaters must go around Antelope Island through the Colorado River channel to reach Warm Creek or go farther up lake.
