Before its flooding, the canyon of the Daugava River between Pļaviņas and Koknese was one of the most outstanding and beautiful parts of the Baltic terrain, and Oliņkalns hill was one of the largest castle hills in Latvia.  The Andrejs cliff as up to 20 metres high, and it was part of the Daugava canyon.  Before the area was flooded because of the construction of the Pļaviņas hydroelectric power plant, there were rapids near the hill that made it hard for rafters to sail down the river.  Today it is a small island in the reservoir of the plant (it can be seen from the side of the Rīga-Daugavpils highway (A6) opposite Stukmaņi).  It is separated from the shore by 300 metres of river, under which the Dūņas valley is now resting.  A small part of the ramparts of the castle hill can still be seen on the island along with the ruins of an open-air stage and a few metres of the dolomite cliff that have remained above water.  It is thought that the Alene castle was on the hill in the 13th century.  Latvian mountain climbers installed a memorial stone in 1998 opposite Oliņkalns hill.

Located on an island in Lake Dviragio, the Salu Estate and its park, when viewed from above, are reminiscent of the boundaries of Lithuania.  The park to the east of the estate is a mixed-type park and is one of the oldest ones in Lithuania.  Back in the day, it was a forest park where trees were never cut down.  The park featured maple, linden, elm, aspen and other local trees, and they are now around 200 years old.  A winding path links the alley to a park trail by the lake.  The various plants and fragments of alleys have survived to the present day.

The White Dune is one of the landmarks of Saulkrasti, on the Vidzeme gulf coast. The dune offers a splendid view of the sea, the mouth of the Inčupe River and the vast beach. The White Dune formed as the wind drove beach sand over the clay silt of Baltic Ice Lake. Its white 18 meters high sand outcrop once helped local fishermen find their way home. The dune got its name from its white, hardened layers of sand which look like sandstone.
In White Dune are set up following Nature Design objects: "Entrance gates" which symbolizes White Dune and its fragility. On the wall of this object an information about White Dune are exposed. "Frīda the Hedgehog" and "Fredis the Rabbit"- both objects invite people to be polite when visiting nature sites and not to throw rubbish on the ground as well as to be quiet in the forest. "The bug trail" which helps to understand that humans are not the only one creatures in the nature. "Listening device" which is made in the form of trumpet and helps to listen into the sounds of sea and wind. The approximately 4 kilometers long Sunset Trail winds from the White Dune to the center of Saulkrasti.

Akmensraga tāpat kā Kolkasraga apkaime jau kopš seniem laikiem ir bijusi zināma kā kuģotājiem bīstama vieta, jo te atrodas viena no lielākajām Latvijas piekrastes kuģu kapsētām. Bīstamības fakts slēpjas apstāklī, ka Akmensraga apkārtnē mainās krasta virziens un jūrā iestiepjas akmeņaini sēkļi. Pirmo signāluguni Akmensragā iededza 1879. g., bet 10 gadus vēlāk uzcēla 28 m augstu koka bāku. 1911. g. uzcēla mūra bāku, kuru sagrāva 1. pasaules kara laikā – 1916. g. Mūsdienās redzamā (augstums 37,5 m, uzbūvēta 1921. g.). Padomju laikā visas bākas bija militāri – stratēģiski objekti un šeit strādāja hidrogrāfiskais dienests un jūras novērošanas punkts. Bākas apkārtnē - mežā vēl joprojām redzamas bijušās padomju armijas ēku drupas. Apskatāma no iekšpuses.

Taka atrodas Riekstusalas pussalā, netālu no putnu vērošanas torņa. Uz peldošiem pontoniem celtā laipa iepazīstina ar Kaņiera ezeru „tuvplānā”. Var iepazīt niedrājus, to putnus, labi redzamo ezera gultni ar zivju mazuļiem un kalcifilām augu sabiedrībām. Laipa aizved līdz salai, uz kuras aug kadiķi.

This is the ancient shore of the Baltic Ice Lake.  We can only imagine the landscape 10,000 years ago, when the Kurzeme peninsula was covered with vegetation reminiscent of a tundra, and waves from the icy lake dashed against the ancient shoreline.  We know that the lake was full of icebergs of various sizes.  Today the cliff is more than 20 km long (some 9 km of it are in the Slītere National Park), and it is as much as 42 m high.  It is the most impressive cliff of its type in all of Latvia.  At the foot of the cliff are the Irve flatlands (the name comes from the Liv 'īrva' or 'īra', both of which refer to deer).  The flatlands are the former bottom of the Baltic Ice Lake.  The Blue Hills are crossed by many small streams and rivers (Pitragupe, Lorumupe, Kaļķupe, Mazupe, etc.).  Their valleys are the basis for a branched and very complicated system of waterways which look particularly impressive when the trees are bare.  In many places the cliffs and valleys display small areas of sandstone from the Narva suite.  These are Latvia's oldest sediment cliffs that can be seen above ground.  Although the Blue Hills are very impressive in scope, there are only a few places where there are important viewing areas (a viewing tower at the Dundaga-Mazirbe road, the view from the Šlītere lighthouse, the view from Mežlīdumi).  The mightiness of the ancient shoreline can truly be enjoyed from the Cirste-Mazirbe road, the Cirste-Riepaldi road, Mežlīdumi and the Vīdala-Melnsils road).  It is worth visiting the area in the springtime, when the slopes of the Blue Hills seem to be sinking under the fresh greenery.

Ap 7 km garā apļveida taka sākas pie leģendārajām Mangaļu mājām. Tā iepazīstina ar latviešu strēlnieku kauju vietām, vietām, kur atradušās to fortifikācijas, t.s. „Vācu valni” u.c. liecībām. Mangaļu mājās – Ziemassvētku kaujām veltīts muzejs.
