The Lake Boruna sign
Features and Overview
Lake Boruna is a large lake that compasses most of the Vendoss swamp, where the river flowing from the Forest of Torian empties into. Around the lake, Zelda can walk along the marsh, but will not find anything there. A man named Faust in the swamp village runs a boat ferry service, and will ferry Zelda to the Mystery Island in the middle of the lake for two Rupees.
Mystery Island is a small, lonely island of mostly sand. Its sole feature is a single palm tree, where by its base a Crystal Heart can be found.
