The Vojsko plateau offers some splendid mtb rides on plenty of tarmac roads. And there are also some single track descents down into the Trebušca river valley. The best among them is the descent down the Pršjak valley which brings you to a splendid viev on the 27 meter high waterfall on this stream.
1300m of altitude difference, 10km of ascent, 13% of average slope, with 20% steepness on the very beginning of ascent just outside Zatolmin - these are some facts that make this way up to Sleme not very popular among mountain bike riders to say the least. But there are some who like it just for these facts. The way up takes some effort but when you get to the top where the highest mountain pasture of Tolmins region lies the view opens to the Julian alps on the East and West side. From here many possibilities for descent are available. The most popular is to go down to Mederje and via Pretovč straight down to Zatolmin. The single track is always empty and it allows a very high speed descent with some rocky sections just to keep the thing interesting.
