The dive
The water is ~6 °C year-round (warmer than other Swedish mines; a 2010 log reports 5 °C) and visibility is up to 40–50 m, but stopes with dark silt swallow the light.

Profile and sections
The water is ~6 °C year-round (warmer than other Swedish mines; a 2010 log reports 5 °C) and visibility is up to 40–50 m, but stopes with dark silt swallow the light. You see rails, ore carts, wooden platforms and chains.
Långban was mined from the 15th century, systematically 1711–1972; the mine flooded after the pumps stopped in 1972. Långban is known for more than 300 minerals. It has been dived since 2005; Värmlands Museum lists four dive sites: Storgruvan, Nya schaktets lave, Kollegiegruvan and Lokaschaktet.
Practical: Långban is ~21 km N of Filipstad. The dive base has a compressor, an O₂ and helium bank, a drying room, and first-response and oxygen kits. The club also runs mine-diver courses.
- Depth and profile
- Levels at -20/-30, -40, -55, -75 and -90 m; exploration teams to -160 m; the mine is 365 m deep. Dan's Room -43 m: ~900 m round trip, ~2 hours swimming. Krubban circuit to -30 m on nitrox, 60–70 min. Deco plateau at -6 m with two habitats (2–4 divers), another habitat at -15 m (one planned at -12 m).
- Intro level
- First level (-20 to -30 m), such as the Krubban circuit on nitrox (60–70 min) — on your own only after your first dive with a keyholder.
- Configuration
- No configuration rules published; roomy drifts. Your allowed depth depends on your training and logged dives. Drysuit with good insulation; the habitats reduce hypothermia risk during long deco or a flooded drysuit.
- DPV: unknown
- No data on scooters or club rules for them.
Who can dive where
- At least Intro to cave
- Cavern zone / easier part: at least Intro to cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 160 m (trimix or deco may be needed)
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
Via Långbans Dyksällskap (with Värmlands Museum): join and upload your certificates on gruvdyk.se, annual fee; booking only through the club. New members first get a tour of the mine area; the first dive is always with a keyholder. After that you may dive the first level (-20 to -30 m) on your own; deeper levels only after logged dive time (electronic log) on the shallower levels and within your training. Entry from the dive platform in Kollegiegruvan (stairs, benches, lights). Dive days per the gruvdyk.se calendar. Lodging: Ericsson Gård.
