Comfortable walking 5–6 km round-trip on uneven terrain with short swims; able to manage light scrambling.
Hike beneath towering limestone walls, swim through luminous pools to a hidden waterfall, then cool off again in the blue eye of Bimmah Sinkhole. This full-day private outing from Muscat blends coastal scenery, canyon geology, and a refreshing dose of Omani culture.
Dawn slips over Muscat’s corniche and the highway bends south, tracing the Gulf of Oman where cliffs lean toward the sea and fishing skiffs bob in protected coves. Quriyat passes in a blur of forts and palm groves before the mountains open to a cleft of green: Wadi Shab. The trail starts gently—gravel and sand underfoot, date palms whispering, a falaj channel murmuring beside you. The canyon narrows and the pools sharpen from jade to electric turquoise, daring you to step in. Water nudges ankles, then knees, then lifts you as the rock walls squeeze close and the final pool pulls you toward the secret cave.

Closed-toe sandals or water shoes handle wet rock, gravel, and stream crossings far better than flip-flops.
Carry at least 2 liters per person; the dry heat sneaks up fast even with canyon shade.
Avoid the canyon during rain or thunderstorm forecasts; flash floods can rise quickly.
A T-shirt or rash guard over swimwear is appreciated around villages and at popular pools.
Quriyat’s coastal fort once guarded maritime routes linking Muscat to Sur, while villages here relied on aflaj—traditional irrigation lines now recognized by UNESCO—for water-sharing and agriculture.
Carry out all trash, avoid cliff jumping that damages fragile ledges, and use reef-safe sunscreen to keep the pools clear. Postpone visits during rain to reduce risk and prevent strain on rescue services.
Wet rock and gravel demand traction and toe protection during crossings and swims.
Heat and dry air increase water needs, especially in summer.
