Eilat is not only about the beach and ocean. A fun activity (though probably not in the heat of the summer) is a chariot ride among the red mountain. Solomon's Chariots leads groups in Nahal Shlomo and Wadi Tzfahot. The clients sit in chariots and guide the donkeys that lead the chariots (not difficult at all). Once on the trail, there is a stop while the leader makes pitas and hands out tea. A bit kitschy but alot of fun among nature. It is a nice off-beat activity to do while in Eilat.
