Boyana Waterfall is the largest waterfall on Vitosha. The waterfall is about 20 meters high. The waterfall can be reached by three main paths. The fastest and relatively easy access is from Kopitoto – it takes about an hour. The other two possible trails start from the area above the Boyana Church. The first one climbs steeply upstream of the Boyanska River and is marked with white and green markings, while the second one is slower but gradually gains altitude, passing close to Boyanska Lake.
