St. Ninian's Isle is a unique site featuring the largest active sand tombolo in the United Kingdom. Snorkelers can explore two distinct coastlines, with the north side typically offering calmer conditions. The topography consists of shell-sand bottoms interspersed with rocky outcrops near the island end. Depths range from 1 to 5 metres, with an average of 3 metres. This site is suitable for intermediate snorkelers who are prepared for cold water conditions, which range from 8C to 13C throughout the year. Access is via the shore, and parking is available. Divers and snorkelers must be aware of potential hazards including surf, rip currents, and the risks associated with cold water.

During the summer the tombolo is above sea level and accessible to walkers, but in winter, stronger wave action removes sand and covers the beach.
The site is connected to the south-western coast of the Mainland, Shetland, by a 500-metre long tombolo known locally as an ayre.
