Leustek trail is very popular MTB uphill access path to peak Sljeme. It is also very popular hiking path so it’s forbidden to ride this trail downhill. There is a tacit agreement between hikers and mountain bikers not to ride downhill this path, so it is very important for everyone who read this text to follow this simple rule. Trail number 9 that starts at Risnjak hut and ends in Mikulići is also very popular with hikers, so if you really want to enjoy, avoid riding this trail downhill during weekends. There are many downhill trails on Medvednica, so you can choose another downhill path.
Leustek – 9 circular route was mine favorite route last few years. But now, because of very high traffic, and because woodcutters massacred singletrack parts on trail 9 I use those trails mostly for uphill.
