The Dole is the largest island in the Daugava River, surrounded to the Northeast by the rapid waters of the Daugava and to the Southwest by calm and gradually overgrown waters from Dry Daugava.  The island is a specially protected nature park, established in 1986 to protect the landscape and cultural and historical values of the island in the wake of the construction of the Rīga hydroelectric power plant, as well as rare and protected species of plants and animals.  The island is also meant to provide education and leisure for visitors.  Best known on the island is the Daugava Museum, which is in the mansion of the old Dole Estate.  The museum features some 13,000 exhibits that speak to the history of the island and the river – Baltic and Livonian apparel, tools and household objects.  The exhibition also presents the Daugava as an important waterway and the related history of forms of transport and rafters.  In the park is an open-air exhibition with reconstructed lamprey eel traps and a barrier to fish salmon, along with a set of fishing tools.  A dolomite cliff is alongside the museum on the steep shore of the Dry Daugava.  The ruins of the Vecdole castle can be found on the south-eastern end of the island, near Bēči.

The viewing tower is on the western part of the Blue Hills of Ogre, not far from the Dubkalni quarry.  Paths lead to the tower, as does a wooden staircase.  The viewing platform offers a very broad view of the Ķegums hydroelectric power plant reservoir and the towers of Rīga.  The platform is part of the nature park of the Blue Hills of Ogre.

The well-appointed Vilce castle hill is next to the Zaķu meadow, which is a nicely appointed and popular place for recreation.

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.

The nature park in the Ogre River valley is found along the middle section of the river. It has been established so as to protect the unregulated river valley and its surrounding territory, as well as biological diversity and habitats. For instance, this is an area in which rare park-type meadows can be found in Latvia. The Ogre is one of Latvia’s most popular rivers for water tourism in the spring, particularly downriver from the town of Ērgļi, where the technically complicated Braži rapids are found.
