Marichini Lakes are two glacial lakes, located in the eastern part of Rila Mountain. They were formed in deep Marichin cirque between Mount Marishki Chal peak Bliznatsite and peak Mancha. Of these springs Maritsa River - the largest drainage basin in Bulgaria, after the Danube.
All pictures from my weekend in Rila can be found here.
It is highly recommended to use BGMountains or other map for additional orientation.
In case the cache is missing I will appreciate if you place a temporary container until I do maintenance. Happy geocaching!
