Skip the city traffic and head straight to the turquoise pools of Bimmah Sinkhole. The water stays refreshing even in the desert heat, so bring a swimsuit. If you're tackling Wadi Shab, prepare for a hike over rocky paths before you reach the cave swim. Book a private day tour if you hate waiting on slow group shuttles. Spend at least six hours here to avoid rushing the best swimming spots. Wear sturdy shoes.
