Garo Belen sits at the exit of the Aber Ildut estuary and changes from very shallow water to moderate depth with the tide. The route is easy to follow as a sand-and-rock boundary with kelp, a sandy tongue, and a distinctive dice-shaped rock. Cracks and holes hold conger eels and lobsters, while the walls are covered in encrusting life, nudibranchs, and dories. It is a good all-level site when you time it to the tide.
