Full-Day Wadi Shab and Bimmah Sinkhole Tour from Muscat: Hike, Swim, and Hidden Caves
Select participants and date
Morning light spills over Oman’s eastern escarpments as the coast road leaves Muscat behind, tracing coves where the Gulf of Oman breathes in and out. At Tiwi, the canyon of Wadi Shab opens like a promise. A short boat shuttle whispers across the inlet, then the trail takes over—rock underfoot, palms flicking shade, falaj channels chattering at your side. The wadi pulls you forward, daring you deeper with each bend.

Adventure Tips
Wear grippy water-ready footwear
Closed-toe water shoes or trail runners with traction make slick limestone and shallow crossings safer and more comfortable.
Hydrate early and often
Carry at least 2 liters per person; sip regularly to stay ahead of Oman’s dry heat, even in cooler months.
Pack for the swim section
Bring a small dry bag for your phone and keys, and expect to swim 50–100 meters through a narrow passage to reach the cave waterfall.
Respect local norms
Swimwear is fine at pools, but carry a light cover-up for hiking near villages and when passing others on the trail.
Local Insights
Wildlife
- Wadi garra fish that nibble at toes in still pools
- Nimble mountain goats along the canyon walls
History
Locals long called Bimmah Sinkhole Hawiyat Najm—“Fallen Star”—before geology identified it as a limestone collapse. Oman’s ancient aflaj irrigation system, seen near Tiwi, is recognized by UNESCO for its ingenuity.
Conservation
Pack out all trash and avoid applying lotions right before swimming to keep pools clear. Stay on established paths to limit erosion in the fragile canyon.
