The bouldering at Filtvet takes place on gneis of good quality. The sector Parkeringen has Hurum's shortest approach, dries fast and mostly takes place on blocks. The Domkirken stone is the largest of the blocks, and has a large variety of problems. Sector Agdeåsen syd and Bølgeveggen is situated in the forest south of the cemetery. On Bølgeveggen there is perhaps Hurum's finest stone quality, while Agdeåsen south houses one of Hurum's finest lines in Den fine linjen.
In the autumn, the Hjortelus fly can be troublesome at times in the forest, and one should always check for ticks after a visit.
It is important to keep a low profile in all sectors for the sake of both churchgoers and cabin people. Do not tread on the graves when passing the graveyard!
Also please leave no traces, remove tickmarks, don't play music, enjoy!
