Protected Red Sea reef at Marsa Samadai, known as Dolphin House, with a sandy bay, shallow lagoon, and horseshoe-shaped coral system that supports resident spinner dolphins. It is a shore-access snorkel and dive site, but park zoning, permit timing, and staying inside the designated areas are part of the plan. The visit works best when you treat it as a regulated wildlife encounter rather than a simple free-entry reef stop.
