Gardur
Gardur is about an hour's drive south of Reykjanes, at the tip of the Reykjanes peninsula. You can enter the water either from the beach or by climbing down a pier ladder. Gardur means "garden" in Icelandic, and it does indeed have a verdant garden of over 42 different species of marine algae. The algae are an important part of the Icelandic marine diet and an ancient food source that was consumed by Iceland's first settlers over 1000 years ago. Algae not only provide basic and essential nutrients, but they also have a colorful and varied design.
You can dive through extensive kelp forests in addition to this lovely garden. These forests provide excellent habitat for a variety of fish species. Wolf fish, scorpion fish, various flatfish, monkfish, and other species can be seen. On your dives, you are recommended to try to pay Tommi the Wolffish a visit, fishes live in a hole in the pier.
