The Slītere National Park (established in 2000) is known, with good reason, as an open-air museum which shows the historical development of the Baltic Sea. Nowadays evidence of geological events is seen in the Blue Hills of Slītere, which stand 20 to 30 metres high above what was the shore of the Baltic lake of ice 10,000 years ago. The Stiebri hills were former 8,000 or 9,000 years ago, while the Littorina Sea formed Europe’s largest set of dune ramparts and damp hollows between those ramparts. This occurred between 4,000 and 7,000 years ago. The gentle climate of Northern Kurzeme is the reason why so many rare plants are found in the park – some 860 in all including Common Yew (Taxus baccata) and Baltic Ivy (Hedera helix var. baltica). Of certain value in the preservation of these treasures was the Soviet military machine, which has left behind army bases and other military objects in the area. The presence of the military meant that the area of what is now the Slītere National Park remained largely undisturbed for 50 years. The park includes one of the most popular tourist destinations in Latvia – the Cape of Kolka, which is visited by more than 50,000 travellers each year. During the spring migration of birds, more than 60,000 birds cross the cape each hour. Along the shore of the Baltic Sea is the so-called Livonian coast, which stretches from Kolka to Sīkrags and Ovīši. Fishing villages and other cultural objects established by the world’s smallest ethnic minority, the Livonians, can be found here. Tourists will enjoy interesting four nature trails, bicycling routes, viewing tower, etc. The visitors centre is located at the Slītere lighthouse. Administration of National park is organising environmental education events on regular basis open to everyone.
