Rising gently above Park Tivoli are the wooded slopes of Rožnik Hill, which is actually comprised of a number of modest peaks and provides a green corridor stretching right to Ljubljana’s northwest fringe. A popular spot for walking and mountain biking, paths crisscross the entire woods, the most interesting amongst them being the Jesenko Path, a 3km trail passing 30 local tree species. Alternatively, take the path up behind the Tivoli Mansion towards Rožnik’s highest peak Šišenski and the far more interesting Cankar's Peak, named after Ivan Cankar, the historic Slovenian author who periodically stayed at the inn on the hill. The popular Pri Matiji inn dating from the early 19th century is still open and is a great place to have a hearty lunch or a cup of tea and flancat, a tasty doughnut-like pastry. Also on the hilltop is a quaint church and, on April 30, the arrival of thousands of locals who gather here for a traditional bonfire party or kresovanje.
