This area protects the landscape of the Lielauce hillocks, which are a part of the Eastern Kurzeme highlands. Lake Zebrus and Lake Svēte are in this territory. On the north-eastern shore of Lake Zebrus one can see the Ezerlūķi castle hill. On the eastern shore of the lake is a boating area, along with a viewing tower and a set of information about the area. The territory includes protected biotopes such as stream swamps and swampy forests, along with protected birds and species of bat.

The shallow and mostly overgrown (65% of its surface) Lake Engure is one of those Latvian lakes which are most favoured by birds. It is a location which is governed by the Ramsar Convention on Wetlands, and 186 species of nesting birds have been identified there. The area is also distinguished by great botanical diversity (more than 800 kinds of plants). The coastline varies between sandy beaches and seashore meadows. There are forests, fishing villages and damp areas which ensure a great diversity in landscapes and species. The flood-land plains of the lake and the sea are grazing grounds for wild livestock – horses, blue cows, etc. Several bird-watching towers are open to visitors, as is the Orchid trail. The Centre for Ornithological Research is located on the eastern bank of Lake Engure. A unique floating house built by ornithologists is located on the lake. The territory is appropriate not just for holiday-makers, but also for hikers, bicyclists and bird-watchers. A leisure area and a small exhibition are located close to the ornithological research centre.

Also known as Lake Jēsis or Lake Iesis, this is the lake in Latvia which has the largest number of islands.  Many literary sources and encyclopaedias in the 20th century claimed that there were 69 islands in the lake, but that was an exaggeration, because apparently the authors took sandbars overgrown with reeds and other plants to be islands.  The true number is approximately two times lesser.  The largest number of islands can be found in the north-eastern part of the lake.  The largest one is Lielā Lāča (Big Bear) Island (45 ha).  A farm was on the island at one time.  The islands and the oak trees that are on the shores of the lake – the Piļoru and Pahatnīku stands of trees – are in a restricted environmental reserve.

This nature park protects the landscapes of the Latgale highlands. Of importance here are Lake Ruskulis and Lake Cīrītis with its eight islands, along with the forests of the area. An ancient castle hill is on one of the islands in Lake Cīrītis – the Upursala island. There and on the Oši island, specialists have found more than 250 species of plants.

This is a comparatively large lake (3 km long and 1.3 km wide).  It is shallow (no more than 1.1 m deep) and is classified as a seashore lake.  The Vecslocene River flows through it.  At the southern end, there is a narrow stream which connects Lake Sloka with Aklo Lake – a shallow and small lake with a dolomite bed at some locations.  The best view of Lake Sloka can be seen from the bird watching tower on its north-western shore.  This is the only floating bird watching tower in Latvia.  Alongside it is the beginning of the 3 km Lake Sloka hiking trail, which passes through the flooded wetlands of the lower reaches of the Vēršupīte.  An information stand can be found on the shore of Lake Sloka by the car park.  Beyond it is a sulphurous spring.
