7–9 hours (incl. transfers); 3–4 hours hiking/swimming
Comfortable hiking 5–6 km over uneven, rocky terrain in warm conditions; confident swimming ability for the final pool.
Swim through Wadi Shab’s hidden keyhole, gaze into the turquoise eye of Bimmah Sinkhole, and walk the white stones of Fins Beach—all on a seamless day trip from Muscat. This coastal tour pairs vivid geology with a moderate canyon hike and a cool-water finale.
Morning light slides across the Gulf of Oman as the 4x4 hugs the coast east of Muscat, cliffs stacked in clean limestone layers marching toward the horizon. Quriyat’s fishing boats rest in the harbor, nets drying in the breeze, while the road tips over a high plateau and drops toward the sea. The first stop feels otherworldly: Bimmah Sinkhole, a perfect turquoise eye punched into pale rock. The water beckons, rippling like it has secrets to tell.

Hit Wadi Shab before 9 a.m. to score parking, softer light, and cooler canyon temperatures.
A short boat ride typically ferries hikers across the wadi’s mouth; carry small Omani rials for the round-trip.
Sturdy water shoes or grippy sandals handle slick rock, gravel, and swimming far better than flip-flops.
Plan on at least 2 liters per person in cooler months, 3–4 liters in summer; the canyon radiates heat.
Quriyat’s coastal watchtowers once guarded trade routes, while ancient aflaj irrigation channels still feed Omani date orchards in nearby wadis.
Use reef-safe sunscreen and avoid jumping from high ledges—limestone edges and aquatic life are fragile. Pack out everything; wadis are easily impacted by litter.
Provide grip on slick limestone and enough protection for gravel and boulder hopping.
Hands-free water access keeps you hydrated on the exposed approach and return hike.
Protects electronics and a light layer when you swim through the keyhole.
The canyon and coast reflect heat and glare—cover up to avoid sunburn and dehydration.
