Ostrog Monastery

"Have the restaurant call Alo Taxi to take you north through the mountains to the lower part of Ostrog Monastery, a Serbian Orthodox Church built within a cliff in 1665. The shrine stands 900 meters above ground in Ostroška Greda, and to get to the top, you’ll have to hike 45 minutes — you’ll see plenty of religious pilgrims do it barefoot, so you should have no problem in hiking shoes and your backpack. The walk will be worth it: It’s one of the most stunning sites of worship, with dozens of religious mosaics and sweeping views of the lush Zeta valley below. "
