Manasija, also known as Resava, is a Serbian Orthodox monastery near Despotovac, Serbia, founded by Despot Stefan Lazarević between 1406 and 1418. The church is dedicated to the Holy Trinity. It is one of the most significant monuments of medieval Serbian culture and it belongs to the "Morava school".

The Resava cave, one of the most beautiful natural treasures of Serbia, is 4.5 km long. However, only 2,830 meters of the cave have been researched, and visitors can go as long as 800 meters deep into it. The Resava is one of the oldest caves in the country (around 80 million years old). The temperature in it is constantly around 7°C, while the air humidity varies from 80 to 100%. The interior of the cave has numerous and varied halls, canals, galleries, columns, stalactites, stalagmites, natural drape like formations and petrified waterfalls. Because of its riches and varied colors, the Resava Cave earned an attribute “the beauty from the Resava”.

25-metre high "Veliki buk" waterfall, Serbia’s most visited waterfall, was long considered the highest waterfall in the country, until the waterfalls on StaraPlanina and Kopaonik were stumbled across. In the nearby restaurants you can taste fresh trout or some grilled meat specialties from this region.

The Krupaj springs are one of the natural curiosities and features of this region. With its splendid beauty, these springs form a lake on its surface and irresistibly lure an unwary traveller to the depths of the forests, to its water and crispy mountain air. The thermal spring watercomplete with health properties mixed with the cold spring water from the Krupaj springs, seem to complete the picture of this almost mythical scenery. Close by there is a strong thermal spring with water temperature of 26.50C, and is protected as a natural heritage of national importance. Researchers into this spring have so far reached a depth of 123 meters.
