Beyond the date plantations that surround Nakhal Fort, this hot spring emerges from the wadi walls and is channelled into a falaj (channel) for the irrigation of the surrounding plantations. There are usually children and goats splashing in the overspill. Look out for the flash of turquoise-winged Indian rollers, among other birds, attracted to the oasis. Picnic tables with shelters, a store and toilets make it popular at weekends.
Take the short cut back to the main road for a fine view of the plantations.
