Oman today_ Bimmah Sinkhole, also known locally as Hawiyat Najm, is one of Oman’s most fascinating natural wonders. Located in the Dabab area of Qurayyat, within the Muscat Governorate, this impressive geological formation lies about 1.5 hours by car from the capital, Muscat. The site is easily accessible via Route 17, the main highway connecting Muscat to Sur. A few kilometers before the town of Tiwi, clear road signs lead visitors toward Hawiyat Najm Park, where the sinkhole is beautifully nestled.
The sinkhole itself is about 20 meters deep and 50 to 70 meters wide, forming a striking turquoise pool surrounded by limestone cliffs. The water inside is a natural blend of freshwater and seawater, as the site lies just a few hundred meters from the coastline. Underground channels allow seawater to seep in, giving the pool its stunning shades of aqua blue and emerald green.
The surrounding Hawiyat Najm Park is well maintained and equipped with facilities such as stairways leading down to the water, shaded picnic areas, walking paths, and restrooms. Entry to the park is free, and it is generally open from 8 a.m. to 8 p.m. Visitors are advised to dress modestly, covering shoulders and knees, in accordance with local customs.
Swimming in the crystal-clear waters of the sinkhole is one of the most popular activities here. However, as some sections are quite deep, it is recommended that less experienced swimmers stay close to the shallow areas for safety.
In summary, Bimmah Sinkhole perfectly combines natural beauty, tranquility, and geological wonder. It is an ideal spot for relaxation, photography, and appreciating one of Oman’s most unique natural attractions. For travelers seeking to experience the country’s quieter, more hidden landscapes, a visit to this enchanting blue oasis is truly unforgettable.
