The Dviete Wetlands Nature Park contains a unique natural territory – the ancient Dviete River valley with the Lake Skuķi and the Lake Dviete and the surrounding wetland meadows. During flooding season, these wetlands store up waters from the Daugava River. They absorb a lot of floodwater at first and then slowly return it, thus reducing the level of floods in the Daugava River valley. This process is the reason for the unique ecosystem which exists in this area. It is an important location for plants and birds both during migration and nesting season. The river valley is important for birds during migration and nesting. In 2006, wild cows were released into the meadows. There is also work to improve the tourist infrastructure in the area.

The nature park in the Daugava River valley is the only place between the cascades of the Daugava hydroelectric power plants there is still a chance to see the Daugava River valley and the ravines of its tributaries as they appeared before the area was flooded so that the power plants could be constructed. Particularly lovely views are found on the right bank of the river near the Aizkraukle church and castle hill. Forests, meadows, origins of streams and small dolomite cliffs in this area are all protected biotopes. Leisure facilities have been installed on the Aizkraukle castle hill, and the Aizkraukle castle ruins are not far away.

The trail climbs up and down along the bluffs of lower River Pilsupe and reveals a fascinating sight of three white dune exposures (the largest is called the White Dune). The trail is 900m long, and the White Dune is ca 20m high. It has formed ca 6000 years ago, in the period of the Littorina Sea which is a foregoer of the Baltic Sea. Here the first Stone Age settlement on the North Western coast of Latvia has been found in 1934 by geologist S. Burhards. In the sand, some 500m from the sea, he found some pottery fragments, a sandstone hone, a piece of flint, parts of bones and an amber bead. He handed the findings over to the National Museum of History. In October 1934, the site was checked by archaeologist E. Šturms, who found the archaeological layer, typical for such settlements, in the landslides of the Pilsupe riverbanks. In 1936 he started larger excavations to continue by 1938. Totally seven, chronologically different settlements were detected and many artefacts found, including fragments of the so called Sārnate and pit-comb pottery, as well as some pieces of corded pottery. Based on these findings, the settlement is dated back to the beginning or middle of the 3rd millenary B.C., and it has been inhabited till the beginning of the 2nd millenary B.C. Especially remarkable are three clay figures in human shape which have probably been used for some religious cult purposes.

Since 1993, archaeologist Ilzes Loze has discovered several pit-comb ware culture settlements in large area around Pūrciems village. They are known in research literature as „the Ģipka settlements”.

The Bauska Nature Park runs for several dozen kilometres along the Lielupe River and its tributaries – the Mūsa and the Mēmele. This is a protected territory. The shores of these rivers contain some of the largest dolomite cliffs in Zemgale. These are protected both as biotopes and as geological monuments. The rivers are important places for river lampreys and vimbas to spawn. Tourists will be attracted by the cultural landscape of the area, as well as the cultural monuments such as the Bauska castle, the Jumpravmuiža park, the Mežotne castle hill, Vīna Hill, the Mežotne castle, etc. The rivers are used for water tourism.

The Wine Hill of Sabile has been known since the age of the Duchy of Courland as the northernmost place where grapes were grown to produce more or less sour wine for the duchy. A wine festival has been held each year during the latter half of July in Sabile since 1999. The hill offers an excellent view of the small town that is on the banks of the ancient Abava River Valley.
