Regions

• RanaCold marble caves just below the Arctic Circle near Mo i Rana: Pluragrotta (main line ~-20 m, deep section to ~-130 m) through the Plura Valley dive centre, its rarely dived second entrance Steinugleflåget and the tighter Litjåga. Water at 1–7 °C, winter visibility up to ~100 m.3 caves · down to 135 m

Good to know

• Pluragrotta and Steinugleflåget are on private land of the Jordbru farm, whose owners run Plura Valley. Check in beforehand; parking and the private road cost €50 per diver per day if you're not staying at Plura Valley. For Litjåga, ask permission to use the private road.
• Plura Valley has its own safety rules: no solo diving, nothing beyond your certification or experience, at least 3 lights, helium deeper than -39 m, CCR only with CCR cave and unit certification, OC bailout from the furthest point, and permanent lines changed only in consultation.
• After an accident in 2014 a temporary access ban applied; it was lifted on 31 March 2014. Diving is allowed today via Plura Valley.
• The water is 1–7 °C (warmest in August), with visibility usually 30–50 m and up to about 100 m in winter. In winter the pool freezes and a hole is cut: drysuit with heating.

Tips for safe and enjoyable diving

• Plura Valley is open all year; peak seasons are March–April and July–September. Visibility drops after heavy rain or during snowmelt. Ask Plura Valley about current conditions.
• The road from Mo i Rana is ~36 km, the last ~5 km rough gravel; snow can lie until June and night frost can come as early as August. There is no mobile coverage at the cave.
• Gas: Plura Valley fills air, nitrox, trimix, O₂ and argon and rents OC, sidemount and CCR equipment.
• Emergency: call 113 (medical) and ask for the on-call diving physician ('dykkerlege'); 112 is the police. The nearest chamber is in Tromsø, ~410 km in a straight line: dive conservatively.
• Rest day: Jordbrugrotta, 3.5 km upstream in Plurdalen, is a wild cave with a lot of water — only with caving experience and the right gear.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training.
