Shallow shore site with rocks, sand, and easy snorkeling in Grevelingen.
Shallow shore site with rocks, sand, and easy snorkeling in Grevelingen.
Longas is a shallow Grevelingenmeer shore site in front of the Carreiros jetty, with mixed rock and sand, overgrown patches, and an easy route that works well for snorkellers and beginner divers. It is a useful fallback when the busier Zeeland sites are crowded, but the outer edge opens into a marked shipping channel, so the dive must stay very shallow and carefully managed.
