    Debeli rtič is the cape at the western tip of the Ankaran peninsula: a flysch cliff 12 to 21 m above the sea, with about 800 m of protected shoreline, among the best preserved in Slovenia. Its tip has been a natural monument since 1991, it's part of Natura 2000, and since June 2018 the whole area has been a landscape park. Almost 700 animal species live underwater.

    What I would do

    I'd walk down from the top of the peninsula through olive groves and vineyards to the cliff late in the day, when Visit Ankaran says the view is finest. And I'd take time over the water, because the sea bed is shallow and full of life.

    What I would keep in mind

    1. 01 Most beautiful

      A sea bed full of life

      Almost 700 animal species live in the sea off Debeli rtič, including more than a third of the fish species found in Slovenian waters.

    2. 02 My tip

      A very shallow sea

      The coastal shelf is so flat that 100 m from the shore it is rarely deeper than 5 m. In winter, low tide uncovers large areas.

      Next to the cape is Debeli rtič beach, one of the largest on the peninsula, with parking nearby.

    What Debeli rtič is

    Visit Ankaran describes about 800 m of shoreline at the western tip of the peninsula, taking in the edge and walls of the cliff, a terrace at its foot and a 200 m coastal strip. The walls rise 12 to 21 m and are made of flysch, a soft rock the waves keep reshaping. At the tip, erosion has left stacks over the reef, and beyond lies a sandbank. A lighthouse standing in the water warns ships off the shallows.

    You reach the cliff from the top of the peninsula, through olive groves and vineyards. The gentler walls are covered with Spanish broom scrub, and above are planted maritime pines and woodland of oak, hop-hornbeam and manna ash. The tourist board recommends the sunset from the top, and the park’s educational trails run through the vineyards, where tractors at work are a common sight.

    A sea full of life

    The real wealth is underwater. The coastal shelf is so flat that 100 m from shore it is rarely deeper than 5 m, and light reaches the bottom. There are meadows of Cymodocea seagrass and algae on the sandstone terraces, and according to the park almost 700 animal species live here, more than a third of the fish species in the Slovenian sea. Among them are rare and endangered species such as the noble pen shell, the long-snouted seahorse, Mediterranean stony coral, the loggerhead turtle and the shag. In winter, low tide uncovers wide stretches.

    Protection and visiting

    The tip of the cape was declared a natural monument in 1991, it belongs to the Natura 2000 network and, at residents’ request and with the unanimous backing of the municipal council, in June 2018 the wider area became a landscape park. For Visit Ankaran, it is one of the best-preserved stretches of the Slovenian coast and key to its biodiversity.

    The beach and getting there

    Next to the cape is Debeli rtič beach, one of the largest on the peninsula, with paid parking nearby and, in summer, the free bus linking Ankaran’s beaches. Out of season, the cape makes for a quiet and very pleasant walk, and the tourist board also suggests it as a starting point for discovering the underwater world. For the rest of the coast, see beaches in Slovenia and the coast and Karst. Debeli rtič is where the Slovenian Mountain Trail starts or ends, depending on your direction, after crossing the country from Pohorje.
