Looking so not attractive, this 1200m hill top doesn't realy look as a favorable mtb destination. So wrong. Its dense forest provides excellent shield from hot summer sun, and the best on this hill starts at its top - descent. If the one from Stol to Kobarid is intense this one is non-stop technical. Steep descent plus many of stone stairs sections on the path makes it really interesting. But surely brings a smile on your face once back in the valley.
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.
