Glaronissia Seagull Island - Crete
Glaronissia, or Seagull Island, offers straightforward diving off Crete's coast. The site features rocky reef formations with a decent variety of smaller Mediterranean fish darting between the crevices. It’s a comfortable dive, good for those looking for a relaxed exploration rather than a high-adrenaline thrill, and suitable for all certification levels. We’ve found it’s a pleasant way to spend an afternoon if you’re already in the area.
