Notes & references:

The route is recommended during summer or fall. Before the ride check the snow condition for Zavižan (Nothern Velebit) zone. Due to many unlabeled junctions the GPS unit with the uploaded route is a must for fast and safe navigation. In attached GPS tracklog 2 shortcuts are included. Use the shortcuts if you want to shorten the route on the section Zavižan Hut – Kuterevo or to avoid the short singletrack section between Otočac and Kuterevo. In Kuterevo and Krasno villages there are small shops. As far as I know the shops don’t work on Sunday or public holidays. The entrance fee is charged in National Park Northern Velebit at Siča Hut ticket office. If you have the valid identification card of Croatian Mountaineering Association 50% discount should be approved.
