About Bimmah Sinkhole
The Bimmah Sinkhole, within Hawaiyat Najm Park, is a natural limestone sinkhole filled with strikingly clear turquoise-green water, formed when the ground above an underground cavern collapsed. Though local legend once attributed the formation to a meteorite strike, geologists attribute it to the gradual dissolving of limestone bedrock, a common process in this part of Oman.
A short staircase leads down from the car park to the water's edge, where visitors can swim in the cool, mineral-rich pool, surrounded by steep rock walls and a small landscaped park. Its location directly beside the main coast road between Muscat and Sur makes it an easy and popular stop for travellers heading to or from Wadi Shab and other attractions along that route.
Why Visit Bimmah Sinkhole?
Local story
Good to Know
The sinkhole suits families, couples and groups, for a visit of 1 to 2 hours, often combined with a longer day trip along the coast road. Modest swimwear is recommended, and shaded seating areas within the park offer a place to rest between swims.
The water can be noticeably cooler than the air temperature, and some small fish are often present in the pool, which is generally considered a harmless and interesting part of the swimming experience.
