Bjelasica stretches from the right bank of the Tara and its northwestern parts belong to the municipality of Mojkovac. It geographically represents the continuation of the mountain range that stretches from Piva mountain, across Durmitor and Sinjajevina, and then goes on from Bjelasica to Komovi and Prokletije. Extending over 30 km in width and length, it covers an area of about 620 square kilometers. Bjelasica is certainly one of the most luxurious mountains in the south of Europe when it comes to its wealth of flora and fauna. It is covered with greenery in all altitude zones with an abundance of water and mountain lakes. It has over 2000 plant species in 26 plant communities and 86 types of trees with specimens over 400 years old. Bjelasica, which covers a large part of the municipality of Mojkovac, is a true splendor of natural beauty in the winter and summer months. In the eyes of skiers, its expanses are a challenge for skiing on rugged terrain, as well as for walking on snowshoes. In summer, they are a real paradise for mountaineers, bikers and other nature lovers.

Bjelasica is one of the biggest potential sites for mountaineering and tourism in Southern Europe. The Tara and Lim rivers wash it with pristine water. Glacier lakes beckon with their secrets, villages and katuns with their hospitality. The highest peak of the north-western part of Bjelasica is Razvršje (2033 m). This peak has extremely steep sides and sharp slopes. In the east, Razvršje is connected to the peak of Crna Lokva, which descends steeply into the valley of the Tara River. Between the peaks of Razvršje and Crna Lokva from the south, and Bjelogrivac, Marinkovac and Mučnica from the southwest, lies the valley of the Bjelojevićka River. There is a low valley with the small Rudnica River carved  between the peaks of Marinkovac and Mučnica. On the sides of this river there are deposits of lead-zinc ore. The main mountain ranges, built of quartz shale and limestone, developed on the Dinaric axis. Unlike other Montenegrin mountains, Bjelasica has a volcanic-silicate composition, so the presence of clastic rocks also determined the abundance of surface water.

North of the Tara Valley, at an altitude of about 1600 m, are the Prošćenske Mountains. These mountains are located in the northwestern part of the municipality of Mojkovac. The Prošćenske Mountains are also an accessible area through which easier communication with the neighboring municipalities of Pljevlja and Bijelo Polje is possible. The highest peak is Ljeljeni Vrh (1856 m), which is located above the place where the Tara River Canyon begins. On its southern side is Veliki Do Cove. The direction of this cove is northwest-southeast. In the south, Veliki Do Cove falls into the canyon of the Tara River with a steep limestone section. In the west, Ljeljeni Vrh transitions gently into the spacious plain of Stupsko Polje. North of Stupsko Polje stretches the limestone cove of Crvena Lokva, which runs from southeast to northwest, and is also inclined in that direction. Numerous sinkholes are spread along the bottom of the cove. It is assumed that Crvena Lokva was created when the Tara River had a much higher level, while a small river flowed through Crvena Lokva itself. Over time, the Tara deepened its bed, and the small river that flowed through this cove began to sink and eventually disappeared. The lower part of Crvena Lokva is surrounded by a saddle, 1440 meters above sea level. Crvena Lokva is above the Tara River Canyon at a height of 760 m.

The area of the Prošćenske Mountains has a large number of coves and sinkholes. To the north-east of Ljeljeni peak is Petrovića Omar, a cove and a cliff covered with dense spruce and fir forest. To the north-east of Petrović Omar there are two smaller coves, Jokića Krlje and Meki Do. To the east of these two, there is the largest cove in the Proscenje area, Burenski Do. The direction of the cove is from northeast to southwest. The length of the Burenski Do is 3.5 km, and the width is 1.5 km. To the east of the cove rises the Buren Limestone Ridge (1631 m). The slightly lower peaks of the Prošćenske Mountains are: Goveđa Glava (1656 m), Ledenice (1689 m), Svevidje (1556 m), Zabrćka Glava (1752 m), Baltića Šiljak (1673 m).

Having seen the natural beauty of these areas, the members of Prošćenske Planina Mountaineering and Sports Club in Mojkovac, with their joint efforts, stone by stone, built the mountain lodge "Prošćenske Planina" for three years. Actually, they had the idea to build their own place for rest, a refuge in untouched nature, a port for travelers.

Lake Zabojsko is located on the north-eastern slopes of Sinjajevina, high above Dobrilovina at an altitude of 1477 m. Lake Zabojsko is 265 m long, in the west-east direction, and 165 m wide. The surface of the lake is 27,600 m², but due to its great depth of 19 meters, Lake Zabojsko is the 3rd deepest lake in Montenegro, right behind Black Lake and Captain's Lake.

Its name comes from the nearby village of Zaboj, which was well visited in the past, during the summer cattle drive. In the southern part, the lake has its greatest depth, 18.8 m, and thus is one of the deepest mountain lakes in Montenegro. Lake Zabojsko has no permanent tributaries, and it gets its water from precipitation, especially from melted snow. The lake can swell to 50 m long, after which the water recedes again. The water of the lake is clear, clean and transparent up to 8 m of depth. The water temperature in the summer is 16°C, while the surface of the lake is frozen for about three months during the winter. The lake is ideal for fishing enthusiasts, because the rainbow trout that the locals call "brkač" lives right here. On the shore of the lake you can enjoy the clear and cold water, the silence and peace that is broken only by the barely audible noise of the mountain spring. A macadam road leads to the lake from the village of Dobrilovina, which is located on the road Mojkovac - Đurđevića Tara. It is also possible to reach the lake with an all-terrain vehicle. If you go on foot, you can take the road, and there are also shortcuts that lead through the forest.

A footpath leads around the lake. The lake is not big, so you can quickly go around the whole area. Next to the lake there is also a source of drinking water. The surrounding forest, in which it is tucked away, is reflected in the water of the lake, which gives it a magnificent color. The view of the lake, which looks like it's from a fairy tale, the silence disturbed only by the birds, and the clean air is all you need to take a break from everyday life.

Lake Zabojsko is surrounded by a dense coniferous and beech forest. Due to its exceptional natural values, it is protected within the Durmitor National Park by a strict conservation regime.

The Đavolje Lazi Gorge is located under the Crna Poda Forest, at the very entrance to the Tara River Canyon. Here, nature narrowed the river bed of the most beautiful European river to only 2-3 meters. This part of the canyon is a special challenge for lovers of wild beauty and extreme kayaking.

Ravnjak springs from below Pećarac. The upper part of the stream is about 2 km long, called Suvoravnjak. It got its name from the fact that there is no water in it throughout the year and it dries up. There is water in it during autumn and spring, as the snow melts on Sinjajevina. The main spring of Ravnjak emerges from under the road to Mojkovac - Đurđevića Tara. From these springs to the mouth of the Tara, the length of the stream is about 3.5 km. The 2.5 km long Ljevak Stream flows into Ravnjak from the left side. It divides the village of Bistrica into two parts. The average yield of the spring is about 1000 l/s. Ravnjak also receives several smaller tributaries in its lower part, which the locals call "makvas.”

The Ravnjak River is about 15 km from the center of Mojkovac, in the direction of Durmitor National Park and Đurđević Tara. It is located at the very entrance to the Tara River Canyon, next to the nearby Hotel Ravnjak, which makes this place very attractive and exceptional in many ways. At its end, the river Ravnjak flows into the famous Tmajevac.

Ravnjak, with beautiful, wild nature where you can often meet Roe deer and fawns near the water, is so clear that every stone can be counted and so clean that you can drink water from it.
