Camp Oaza

For spectacular days out and about in nature, a trip over the border into Romania is a must. The site is a 45-minute drive from Nera Gorge-Beușnița National Park, where there are stunning waterfalls, lakes and caves to explore, including the famed Bigar waterfall and Ochiul Beiului lake. A little further on is Semenic-Caraș Gorge National Park (an hour and 10 minutes away), where there are more falls, lakes and caves, as well as some fab ski slopes if stays coincide with snowier months. Nature cravings still not satisfied? The Serbian Fruška Gora National Park is just under three hours away, and the rare animals of Koviljsko Petrovaradinske Rit Special Nature Reserve can be observed within two and a quarter hours. There’s plenty of history hereabouts if boffins want to dive in: the 15th-century Serb Orthodox Mesić and Bavanište monasteries are both within 50 minutes, and the Romanian Mănăstirea Călugăra and Nera Monastery are less than an hour from base. If castles are more of an appeal, then head to Smederevo Fortress or Kapetanovo, both about an hour away. For wider swathes of history, consider a trip to Belgrade instead. The capital is just over an hour and a half's drive from the site and has museums, churches and historical sites to roam around, as well as zoos, theatres, restaurants and shops.
