Company data
Why Dalarö is different
The Baltic Sea is cold, dark and almost fresh, and the shipworm Teredo navalis that eats wooden wrecks everywhere else in the world cannot survive in it. The result is a seabed full of intact wooden ships from the 17th century, still standing, still rigged in places — something that exists almost nowhere else on Earth. Vrakdykarpensionatet Captain Baltic, at Dalarö in the Stockholm archipelago, is a dive base built on exactly that.
The centre's own description: world-class wreck diving among intact 17th-century wrecks and old cargo ships, with stories of storms, sea battles and bad luck that sank many ships in the Baltic's green water. It states it has 50+ wrecks to choose from and can dive in any wind direction, with depths from 5 to 40 m across everything from the Swedish Empire period to modern steel wrecks — all natural sinkings, not scuttled attractions.
Wreck Weekend
The signature product is the Wreck Weekend (VRAK-helg) in Dalarö, sold in three lengths. All packages run with a maximum of 8 divers per group and a dive leader always in the water, with a mix of historic timber and steel wrecks in the inner and outer archipelago chosen on the day according to wind and weather.
3 days (Fri–Sun) — 1 evening dive + 4 boat dives, from 6,800 SEK. Arrival Friday afternoon with an evening dive, then two boat dives each on Saturday and Sunday.
4 days (Thu–Sun) — 1 evening dive + 6 boat dives, from 9,900 SEK. The centre's most popular package.
5 days (Wed–Sun) — 1 evening dive + 8 boat dives, from 12,800 SEK.
Training
Captain Baltic is a PADI 5 Star IDC Dive Resort, running courses from beginner to professional and technical. One house rule is worth knowing before you book: all courses are done in a drysuit for safety reasons, so a diver who has never used one starts with the drysuit course.
The course list covers DPV scooter, try-dives, Scuba Review / ReActivate refreshers, Open Water (standard and a premium 10-dive intensive), Advanced & Nitrox to 30 m, Nitrox, drysuit, trim, Rescue Diver, EFR, Deep & Wreck to 40 m, night diving, a Baltic Sea environment specialty, Tec Basics, Tec 40 and Tec 45, tec private lessons, Open Water referrals, private lessons and historic wreck training.
Shop, gas and membership
The centre runs a dive shop — online always open; the physical shop closed Mondays and Tuesdays, open on request Wednesday to Friday 13:00–17:00 and alongside dive trips — plus gas filling and the Dalarö Dykpark.

It gives 50% off shore dives and member boat dives, 10% off equipment, trips and courses, member-only events, a members' WhatsApp group where special trips are released first, a newsletter and a club T-shirt.

Frequently asked questions
Why are Baltic wrecks so well preserved?
The shipworm Teredo navalis, which destroys wooden wrecks in most of the world's oceans, cannot survive the Baltic's low salinity. Combined with cold water and low light, that leaves 17th-century timber ships standing intact on the seabed.
How much is a wreck weekend?
From 6,800 SEK for 3 days (1 evening dive + 4 boat dives), from 9,900 SEK for 4 days (1 evening dive + 6 boat dives) and from 12,800 SEK for 5 days (1 evening dive + 8 boat dives).
Do I need a drysuit?
Yes. All courses at Captain Baltic are run in a drysuit for safety reasons. If you have never dived dry, you start with the drysuit course.
How deep are the dives?
Between 5 and 40 m, across more than 50 wrecks, with the site chosen on the day according to wind and weather.
Does the centre run technical courses?
Yes — Tec Basics, Tec 40 and Tec 45, plus tec private lessons, alongside the full PADI recreational and professional range as a 5 Star IDC Dive Resort.
What does membership include?
1,500 SEK a year, which also makes you a member of Dalarö Dyksällskap: 50% off shore and member boat dives, 10% off equipment, trips and courses, member-only events and WhatsApp group, newsletter and a club T-shirt.
