A turquoise limestone sinkhole inside Hawiyat Najm Park, with a fence, toilets and a stairway to the water. Shoot from the stairs and rim for the colour contrast, and from the water at midday when the sun reaches the surface.
The Bimmah Sinkhole sits inside Hawiyat Najm Park at Bimmah, beside Route 17 on the coast road between Muscat and Sur in Oman. It is a limestone sinkhole with a turquoise pool at the bottom, surrounded by a fence, with toilets and a stairway that descends to the water. The main frames are the colour contrast between the pale limestone rim and the vivid turquoise water, seen from the rim, from the stairs and from the water itself. A wide-angle lens from the rim captures the whole bowl, while from the stairs the water fills the lower half of the frame with steps leading in. Light is the key constraint: the sinkhole is deep, so the water only glows brightly when the sun is high, which makes late morning to midday the best time, in contrast to most landscape subjects. A polariser reduces surface glare and deepens the colour, and a waterproof case allows shots from within the water. The best season is October to April, when the weather is comfortable; summer is very hot, although the water is refreshing. The site is busiest at weekends and in the middle of the day when coach groups stop on the road between Muscat and Sur, so early arrival gives a cleaner rim and stairs. Tripods are practical on the rim but should not block the stairs. The park has an entrance fee policy that visitors should check locally, and drone flights need authorisation in Oman and are not suited to a small, busy site. Swimming is allowed, so visitors should wear a swimsuit and bring a towel, and cameras not rated for water should stay on the rim. Toilets are available at the park.
