This wadi is arguably one of the most gorgeous destinations in Oman. Beyond the breathtaking entrance, the wadi rewards you with views of aquamarine pools, waterfalls and terraced plantations; kingfishers add glorious splashes of colour. For the adventurous, there are plenty of opportunities for (discreet) swimming and a visit to a partially submerged cave.
SamailIf you have your own vehicle, it's worth visiting Samail. A fort and Oman's oldest mosque are hidden in the plantations but the real attraction is the lush oasis through which the road passes. Masjid Mazin bin Ghadouba Mosque, with wooden lintels and stained-glass windows, has been completely rebuilt and is constructed from blocks of stone.
Jabrin CastleRising without competition from the surrounding plain, Jabrin Castle is an impressive sight. Even if you have had a surfeit of fortifications, make the effort to climb one more keep as Jabrin is one of the best preserved and whimsical of them all. Head for the flagpole for a bird's-eye view of the latticed-window courtyard at the heart of the keep.
