If you want to beat the crowds at Wadi Bani Khalid, then search for Moqal Cave in the upper reaches of the wadi. Look for a lower path above the picnic area and walk along the bottom of the wadi. You will have to scramble over and squeeze under boulders and ford the water several times. For precise directions, ask the goat herders. If they don’t tell you the right place, it’s because they don’t like tourists penetrating deeper into the wadi.
Then again, they may just be worried you’ll be lured into the land of gardens and cool streams revealed to all who strike the rocks of Moqal Cave and utter the magic words ‘Salim Bin Saliym Salam’. The cave, however, is more likely to reveal evidence of bats and previous visitors. The narrow entrance is finally accessed by a concrete stairway. A torch is needed to see anything, and to find the underground pools, you will need to be prepared to scramble and slither through the mud. To reach the cave, walking shoes are advisable, together with a reasonable level of fitness. If the water levels are high, the route should be avoided. It's inadvisable to enter the cave alone.
