Sundahöfn | Reykjavik Harbour Wrecks
Site Overview
Sundahöfn is Reykjavik’s working harbour and a surprisingly rich dive spot, home to the sunken tugboat Sundabáturinn at 12 to 20 metres and the Elliðaeyjarsund wrecks. These structures are heavily encrusted with sea anemones and kelp and attract resident lumpsuckers, cod and flatfish, making the harbour a favourite for night dives and macro photography right in the capital. A short boat ride from the city centre puts you on the wrecks, and the long summer light means near-daylight night dives are possible. Water is 4 to 11°C and a drysuit is mandatory, with mild current and boat traffic the main considerations. For travellers based in Reykjavik, Sundahöfn offers convenient, characterful cold-water diving with good life and an urban backdrop that few capitals can match. The site is a rewarding but demanding cold-water dive that rewards preparation, good buoyancy and respect for the Icelandic environment.

Dive Briefing
"Meet your operator at the Reykjavik harbour and kit up on the boat. The short trip reaches the Sundabáturinn tug; descend to the hull and orbit it, watching for lumpsuckers on the deck and cod in the beams. Move to the Elliðaeyjarsund wrecks for anemone-covered structure and macro life. There is mild current, so swim into it on exit. Only tech-trained divers enter the wrecks; others stay outside. Water is 4 to 11°C, so monitor warmth. Complete a safety stop and signal the boat. A local operator manages timing around harbour traffic and the calmest light, including summer night dives. Follow your guide closely, monitor your thermal comfort and ascend with a safety stop before exiting at the designated point.

Traveler Notes
Who is this for?
Sundahöfn suits intermediate drysuit divers who want convenient city diving with wrecks and macro. It is excellent for night dives and photographers, and for travellers short on time in Reykjavik. Penetration is for tech divers only; everyone else tours the exteriors. It is less pristine than remote sites but offers great life and an easy logistics chain, making it a fun, accessible capital dive with a guide. It suits confident cold-water divers who value unique geology and pristine conditions over abundant tropical marine life.
