We used wade-fishing pants, high enough to reach our armpits. But they were not high enough to protect us completely from the water, as it was too deep in places. In a couple of points we had to either jump a few meters or swim. This would not have been such an issue, but doing that while carrying two cameras was a challenge for me. In some other points we held on to rocks on the tunnel walls to keep ourselves afloat. In another case we had to move on our bottoms along a small underwater ledge in the tunnel wall.
The cameras survived, albeit a bit dirty from all that clay. But most of us had taken in some water during the trip. The advice from our guides was that if water starts pouring to our pants, there is no point in raising the issue - we better keep going and pass the difficult point. And the organisers have a system for drying the pants :-)
A tourist tour into the Lummelunda cave costs 130 SEK or about 13 €. The adventure tour costs 800 SEK or about 80 €.
