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.

Ķekavas novadā, Daugmales pagastā atrodas jauka atpūtas vieta - Lejas ezers. Ezeram var apiet apkārt, taka nav marķēta un iešana ir pa mazām meža taciņām. Slapjākā laikā taciņas vietām var būt mitras un dubļainas. Pastaiga aizņems aptuveni stundu. Pie ezera ir iekārtotas vairākas piknika vietas.

This nature park was established to protect the Burzava hillocks, Lake Adamova (a eutrophic lake), and the habitats and species that are found along the lake’s shores – bats included. The loveliest views of the area can be viewed from the hillocks that are on the northern shore of the lake. There are tourist accommodations on the shores of Lake Adamova where tourists can spend the night.

This nature park is located in the most distinct part of the Dagda hillocks of the Latgale highlands. Part of it is the deepest lake in the Baltic States -- Lake Drīdzis, which is 63.1 metres deep and has nine islands. Also there is Lake Otis. The loveliest views can be watched from the ancient Lettigalian castle hill that is known as Sauleskalns, and from the eastern shores of Lake Drīdzis. Accommodations are available near the lake.

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.
