Timing notes & visitor warnings
Boat fee: The mandatory boat crossing costs 1 OMR per person (round trip, cash only).
Last entry: While the wadi doesn't "close," you must catch the last boat back (typically 5:00 PM) to avoid being stranded.
Flash flood risk: Never enter the wadi during rain or if rain is forecast; flash floods are extremely dangerous and occur with little warning.
Swimming proficiency: Only confident swimmers should attempt the final pool and the "keyhole" entrance to the hidden cave.
Check the weather
Please keep in mind that boat crossings and trail access are subject to change based on local weather conditions; it is especially important to monitor for rain, as flash floods can occur suddenly and may affect the safety and accessibility of the wadi.

Night services and last departures
While Wadi Shab and the Bimmah Sinkhole are primarily daytime attractions, understanding the final departure times is critical to ensure a safe return.
Last boat at Wadi Shab: The final boat crossing to return to the parking area typically departs at 5pm. Ensure you begin your hike back from the pools no later than 4:00 PM to catch this last service and avoid being stranded.
No night swimming: There are no lighting facilities within Wadi Shab. Swimming or hiking after dusk is highly dangerous due to the uneven, rocky terrain and lack of visibility.
Bimmah Sinkhole park closure: Hawiyat Najm Park, which houses the sinkhole, closes its gates strictly at 8pm. Visitors are expected to exit the water and the park premises by this time.
Safety considerations: For both locations, public transportation and taxi services become scarce after sunset. It is recommended to have a pre-arranged vehicle or depart well before dark.
