This is a segment of the shore of the Bay of Rīga that is around 40 km long and features the valleys of three major rivers – the Lielupe, Daugava and Gauja river.  There are dune formations, biotopes, seashore meadows and forested seashore dunes which are an important recreational resource.

This nature park is one of the richest and most unusual nature parks in Latvia in terms of its natural resources, the surrounding environment, the landscapes, the biological diversity of the area, and the cultural monuments which are found there. The main treasure there is the little-changed Daugava River valley, where there are eight major curves in the river at a length of four to eight kilometres. There are also the gullies of river tributaries. Outstanding views can be found on the steep shores of the Daugava River valley, particularly the Slutiški and Ververi cliffs and the Elerne gravel hill. There are some 20 archaeological monuments on the shores of the valley -- ancient castle hills at Najene, Markova, Vecračina, etc., countless churches -- the Juzefova, Sprukti, Borovka, Elerne, Sīķele, Kaplava and other churches, the Rozališki, Lielborne and other baronia estates, and the unique village of Slutiški, which is home to the Old Believers. There are interesting nature trails and bicycling trails in the area. Horseback riding is available, and there is a viewing tower along with other elements for tourists. Boating down the Daugava River is an interesting way to spend time.

The Naujene castle hill is on the steep bank of the Daugava River, is up to 25 metres high and has two valleys on its sides.  Between 1275 and 1277, the master of the Livonian Order, Ernst von Ratzenburg, organised the construction of a brick castle to replace a Lettigalian wooden castle that had stood there before.  The castle had a drawbridge and an external and internal forecastle.  Until the middle part of the 16th century, the castle was the residence of one of the top officials in Dünaburg.  The forces of Ivan the Terrible sacked the castle in 1577, after which the location lost its strategic importance.  New fortifications were built in the location that is now the city of Daugavpils.  Alongside the ruins of the castle is a miniature model that helps to imagine the appearance of the location many centuries ago.  A well-appointed pathway leads from the car park to the castle hill.  The hill offers one of the loveliest views of the curvy Daugava River and its surrounding nature park.

This territory was established to protect various kinds of rare butterflies A popular tourist destination in the Nīcgaļi forests is the great rock of Nīcgale, which is the largest rock in Latvia – a geological and geo-morphological monument of nature. The rock has a circumference of 31.1 metres, and it is 3.5 metres high, 10.5 metres long and 10.4 metres wide for a total size of 170 m3.

This comparatively large territory is found to the South of the Irbe River and Stende River, and it is unique with more or less virginal forests and dunes. The Irbe River has a system of ancient tributaries, and the Dižpurvs swamp is parallel to the shoreline. The Irbe has become a popular river for water tourism in recent years, but the tourist infrastructure on its banks remains insufficient. Territory has good road connections and has potential for nature education activities.
