It seems like an innocent small hill looking at it from Tolmin or Most na Soči. But proves to be a hard one. The overall length of this tour hardly beats the one to Vodil Vrh but even if you tried that one and think it is hard to seize than Bučenica will remain an unconquered hill top for you. The uphill part is so difficult due to terrain that the cycling do-ability is on its extreme limits ... but once on top it all gets repaid with two amazing view points. The downhill single-track offers a fast and smooth descent back down to Most na Soči. And a beer or two makes you wonder how come this short trip was so fatiguing ...
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.
