The nature park in the Ogre River valley is found along the middle section of the river. It has been established so as to protect the unregulated river valley and its surrounding territory, as well as biological diversity and habitats. For instance, this is an area in which rare park-type meadows can be found in Latvia. The Ogre is one of Latvia’s most popular rivers for water tourism in the spring, particularly downriver from the town of Ērgļi, where the technically complicated Braži rapids are found.

The Vilce Nature Park is small in size and exists alongside the deep valleys of the Vilce River and its tributaries. Biotopes include visible sandstone cliffs, rapids on the rivers, forests typical of such areas, and the plants and animals that are found therein. The well-appointed Vilce castle hill is next to the Zaķu meadow, which is a nicely appointed and popular place for recreation.

This nature park covers an area of the Baltic Sea coast and part of newly established sea protected area "Nida - Pērkone" with sand dunes which once used to move around but have now settled. These are the highest dunes in Latvia. Visitors will enjoy the coastal landscape, sandy beaches and small fishing villages of the area. A nature trail has been established on Pūsēni Hill (one of the highest dunes in Latvia) for those who wish to tour the nature park.

The Sunset trail starts in the centre of Saulkrasti town and takes you to the White Dune. Saulkrasti town with its municipal rural territory, occupies a 17km long stretch of coastal land to the North from the river Lilaste and the lake Lilaste.

The White Dune stands on the right side of river Inčupe mouth. It is covered by old pine forest. The white, 18m high sand outcrop in olden times served as a landmark for fishermen. The White Dune formed as winds carried the sand from the beach over clay sediments of the Baltic Ice Lake. Some 150-200 years ago, the dune had been drifting as witnessed by several layers of soil buried within it. Local fishermen and farmers at Bātciems initiated afforestation of the drifting dunes. At that time, the 30m high dunes which are now covered with forest, were bare, shifting and even buried a farmstead. To speed up afforestation, mountain pines were planted. The White Dune was partly washed away in heavy storm in 1969, and 4-6m high precipice formed. Now the wind and sand have levelled out the dune surface, it has been fixed with willow-twigs or grown with forest where the largest pines are more than 170-190 years old. The pines are notable with their large trunks and branches, the scars obtained during their lifetime and the typical “crocodile skin” – the bark forms rhombuses resembling those of the reptile’s scales. Scots Pine (Pinus Silvestris) is one of the most common tree species in Latvia. It grows in dry, meagre sandy soil in dunes as well as in marsh. However, it does not stand overshadowing. Forest fires help pines to get rid of competitors as pine endures fire better than other trees because of its thick bark and high crown. The wood exudes resin and burned wounds close soon. Fire cleans space for seedlings of young pines. Pines can live 300-350 years.

Ground cover in dune forests is very sensitive. If the sparse vegetation is destroyed, not only the natural biodiversity and landscape is damaged, but also the dangerous shifting dunes can possibly “wake up”.

Embryonic dunes, White (yellow) dunes, Grey dunes and Wooded dunes are EU protected biotopes. Grey Dunes are protected by Latvian law as well.
A wooden trail with watching platform is built to protect the White Dune and to facilitate the sightseeing. In winter, a skiing trail in the vicinity of the White Dune is arranged.

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.
