7–8 hours
Comfortable hiking 6 km on uneven terrain with light scrambling and confident swimming 50–100 m.
Trade the city for canyon light and electric-blue water. This private day from Muscat pairs Wadi Shab’s hike-and-swim pools with the surreal plunge of Bimmah Sinkhole—handled end-to-end by a local guide so you can move light and linger where it counts.
The highway slips east out of Muscat and the Gulf of Oman keeps pace, flashing turquoise as limestone bluffs shoulder the road. Villages appear and fade—date palms gathered around silver falaj channels—until the mountains split and a canyon opens its mouth. Wadi Shab calls you in. The wadi’s stream braids through boulders, urging you upstream as cliffs rise on both sides and palms throw shade that moves like a slow tide.

Heat builds quickly; aim to reach Wadi Shab trailhead by 8 a.m. for shade on the approach and calmer pools.
The route mixes dry trail, slick rock, and swimming—closed-toe water shoes with tread beat flip-flops.
A small local shuttle boat is required to cross the inlet at Wadi Shab (about 1 OMR per person, cash only).
Avoid wadis during heavy rain forecasts; water can rise fast and exits are limited.
Aflaj irrigation has sustained Omani agriculture for over a millennium and is inscribed by UNESCO for its ingenuity and community management. Bimmah Sinkhole’s name, Hawiyat Najm—‘the Falling Star’—echoes the legend of a meteor, though it’s a limestone collapse.
Pack out all trash and avoid lotions before swimming to keep the freshwater pools clear. Stay on established paths to limit erosion on fragile limestone.
Provide traction on slick limestone and protect toes during boulder hopping and swims.
High heat and dry air demand steady hydration, especially in summer.

Keeps electronics and documents safe during the swim to the cave waterfall.
Open canyon segments and the sinkhole rim offer little shade; protect skin and eyes.
