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.

Maršruts "Murjāņi - Līgatne" ved caur Gaujas senieleju ar devona smilšakmens atsegumiem, raksturīgo augu valsti un dzīvniekiem. Krastos sastopami Latvijā lielākie nogāžu un gravu meži ar liepām, ozoliem, gobām un ošiem. Upes līkumos palienē aug baltalkšņu un vīksnu audzes. Uz koku stumbriem atrodams plaušķērpis. Senieleja bagāta ar sausokņiem un kritalām, tāpēc Gaujas krastu mežos dzīvo visu Latvijā sastopamo dzeņu dzimtas sugu putni. Smilšainajās Gaujmalas pļavās un Gaujas vecupēs ir bagātīga bezmugurkaulnieku fauna. Upes krastos ir smilšakmens klintis ar čurkstu alām un zivju dzenīša ligzdām. Klinšu pakājē iztek avoti, kas uztur mikroklimatu ielejā. Gauja ir nozīmīga arī kā Latvijas lielākā lašupe. Maršruts ir daļēji marķēts un papildināts ar norādēm un informācijas stendiem.

35 m wide and 0.5 m high, the Abava River waterfall has a location for tents, a swing set, and locations for picnics and campfires.  The site is open all year long, and the Sabile wine hill is nearby, along with the Pedvāle Open-Air Art Museum, a trolley ride known as “the Windmill of Svente,” and other interesthing things to see

This trail of pathways dates back to 2005 and it passes from the Dunte Estate (which has an exhibition about Munchhausen) along damp shoreline forests and on to the sea.  There are rest stops along the trail with wooden sculptures related to the famous Baron Munchhausen, as well as other attractions.  The trails are in the Northern Vidzeme Biosphere Reserve.
