Manastir Beach - Alonissos Marine Park

Diving Haswell Reef isn't your typical tropical drift, but it offers a genuinely wild Alaskan experience. We’ve seen healthy bull kelp forests here, swaying with the currents, providing cover for a surprising number of critters. Keep an eye out for colorful nudibranchs clinging to the fronds and the occasional wolf eel peeking from a crevice. It’s a spot best suited for divers who appreciate temperate water ecosystems and the quiet thrill of discovering life in unexpected places. You might even spot a harbor seal zipping by, curious about your bubbles.
