Numerous diverse mountain areas are well suited for mountain climbing. Many well-marked paths testify to the long tradition of this recreation in Croatia. The mountain climbing/hiking season in our country practically lasts all year long. Our mountains are not high - Croatia is the only country in the European southeast without a single summit above 2,000 metres, but is remark- able for their attractiveness. The most notable attractions mountain hikers are: the Risnjak national park, the entire Velebit mountain, mountains of Gorski Kotar, as well as numerous mountain destinations in the proximity of major cities. The markings in the mountains are standardised: a red circle with a white spot in the centre. Thin trees are exceptionally marked by two red stripes with a white one in their midst. Some 50 m before a crossing, the x mark is placed. Presently, there are around 250qualified group outing guides for summer and winter forays in Croatia. They are active on an amateur basis, and they are united in guide stations. The stations provide guides to larger groups and less experienced hikers, especially in cases of areas that are difficult for orientation or in the technical sense. Most of the stations are located in mountain climbing associations, but some are also independent.
Lovers of mountain climbing and hiking over numerous mountains of higher and lower altitude can take advantage of more than eighty mountain lodges and shelters. Special maps designating footpaths and marked mountain trails and all the accompanying information are also available.
