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.

Dabas takā gar Rojas upi iespējamas 3 dažāda garuma distances, kas lokveidā ved gar upi un tai pieguļošajiem mežiem – 2 km, 7 km un 15 km, kas katra atzīmēta ar savas krāsas norādēm. Dzeltenais aplis 2 km, zilais aplis – 7 km, sarkanais aplis – 15 km. Maršrutus var veikt arī ar velosipēdu, taču braucot ar velo, atsevišķi posmi var būt grūti izbraucami smilšu dēļ.

Pie upes ierīkotas vairākas atpūtas vietas ar soliem, galdiem, labierīcībām, šūpolēm, vingrošanas konstrukcijām, atkritumu urnām, kā arī ugunskura un telšu vietām. Pie atpūtas vietām Žocenē un Rojā ir izveidotas arī laivu piestātnes. Takas sākumā upes krastā labiekārtota vieta, kur upē ietek Rojas avots, ko kā ūdensņemšanas vietu iecienījuši vietējie iedzīvotāji.

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.

Lake Liepāja is shallow and eutrophic (around 40%), and it is one of the most important lakes on the shores of the Baltic Sea for nesting and migrating birds (resting and feeding place). More than 100 different species of birds have been spotted there. The lake is no less important for plants which flourish in salty biotopes. On the north-eastern shore of Lake Liepāja (Vītiņu meadow) there are flood-land plains which are the home to domestic animals which have been adapted to life in the wild. There is also a viewing tower, available upon request with the guide. The system of dams along the south-western part of the lake can be hiked or biked (extreme!) to find lots of interesting viewing areas and landscapes. In the surrounding of the lake there are ruins of unique former fortification systems.

This territory is to the North of Skrunda, and it is an important location for water birds during their migration. Northern swans nest in the ponds, and sea eagles and other birds such as falcons and plovers use them for feeding. This is a good place for bird-watching, although it has not been particularly structured for that purpose.

An impressive two-trunk tree at the Nigliņi homestead, this is one of the most impressive trees on the Liv Shore.  The Liv language teacher Zoja Sīle was born here.  The Medieval Old Cemetery Hill – once used as burial grounds – is nearby.
