This beautiful waterfall is only 5 km away from Kalna, on the road to Pirot. (From Nis, you can reach it if you drive through Svrljig towards Kalna, it's 63 km away).
Waterfall Bigar is very near the village Stanjinac, and it is 35 m high. In the past it was a favorite resort of villagers from the surrounding villages, and today the visitors are mostly nature and adventure lovers. Nearby is the Monastery of St. Onurfija from the thirteenth century, and three lakes with low cascades.
The cache is a small plastic photo film canister, with the logbook. It is hidden in a nearby cave to the left of the parking space. You can reach it if you cross a small wooden bridge. The cache is in the left side cave wall, inside a hole and covered with a stone. When you are inside the cave you should be protected from the muggles but still be careful when getting and returning the cache.
IMPORTANT: in case the cache is damaged or missing, the owner can visit the location and replace it only once a year.
In case you have difficulties finding the cache, look at the spoiler photos.
Have fun and enjoy the beauty of this waterfall!
