This territory is meant to protect the “green zone” of Rīga. Most of the park is covered with pine forest and dunes with shrubs on them, but Lake Beberbeķi is found at the southern end of the park. The area around the lake has been improved.

One of the highest dunes in Latvia, located between Bernāti and Jūrmalciems villages. It is 37m high and offers a magnificent view of the sea and natural pine forests. The highest dunes in Latvia stand to the South of Jūrmalciems village: the Pūsēnu hill, the Ķupu hill, the Mietragkalns or Tiesas hill, the Pāļu hill, the Garais hill, the Ātrais hill, the Lāvas hill. The Pūsēnu dune is the highest of these dunes which are all called hills by the local people. The Pūsēnu hill developed between 1785 to 1835 when shifting sand became extremely dangerous. Several homesteads were buried in sand, among them „Pūsēni”, where a forester’s family lived. The family is said to have moved to Bārta. The dune was named after the buried homestead.

Jēkabs Janševskis, a Latvian writer, wrote in his book „Nīca”: “In olden times, large pine trees were growing in the dunes on the coast of Nīca and they stood steady and firm. But i Swedish times (around 1650), the Swedes built a large kiln for charcoal and tar. Pine wood and stumps provided an excellent material for this. Once a big fire rose, and the charcoal kiln burned down as well as the whole pine forest. The remaining stumps and bare trunks in the vast burnout could not hold the storm-driven sand; it flew further and further burying not only the burned-out forest, but also the nearest fields. In wintertime, when the vast, low marshy grasslands were covered with ice, jets of sand drifted further over its surface, and soon most of the grasslands and large meadows turned into sandy heath-land and dunes.”

To reconstruct Liepāja, severely damaged during WWII, a silicate brick factory was built in the town. The main raw material was white sand and it was taken from the Bernātu forest. In the 1960-ies they started to dig off the Green Dune and the White Dune, later also the Pūsēnu hill. The excavators used to work day and night, in three shifts. The work stopped at around 1980, as there was no more sand suitable for production of brick.

A trail is set up to facilitate walking in the Pūsēnu Dune in the Bernātu 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 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.

Nepilnus 3 km garā taka iepazīstina ar dziļo Imulas ieleju – Abavas kreisā krasta pieteku. Īpaši iespaidīga ieleja izskatās bezlapu periodā, kad ir apjaušami tās izmēri un formas. Viens no takas iespaidīgākajiem objektiem ir Buses jeb Matkules pilskalns. Apskatāmi citi objekti – Baznīckalns, Bedrīšakmens, Ķauķa kalns ar avotiņu. Atrodas dabas parkā „Abavas senleja”.

Veisieji reģionālais parks (Veisiejų regioninis parkas) veidots (1992.g.) Sudavas augstienes (Sūduvos aukštuma) ainavu, bioloģiskās daudzveidības un kultūras pieminekļu aizsardzībai. Viena no parka bagātībām ir ezeri, kuru iegarenās formas liecina par ledāja darbības rezultātu. Pēdējā apledojuma laikā šeit atradusies ledāja mala. Ezerus (kopā – 37) ieskauj lielāki meža masīvi uz kontinentālām (iekšzemes) kāpām, kas piemēroti atpūtai dabā, dabas vērošanai, ogošanai un sēņošanai. Parkā ir iekārtotas peldvietas, kur patīkami gremdēties vasaras tveicē, izveidotas dabas takas, bet mazās upītes, kas savieno ezerus, ir piemērotas braucieniem ar kanoe laivām. Veisieji reģionālā parka teritorijā ir liela augu un dzīvnieku daudzveidība. Šeit tiek aizsargātas arī tādas retas sugas kā Eiropas kokuvarde Hyla arborea (parka simbols), purva bruņurupucis Emys orbicularis, dažādas orhideju sugas u.c.
