Fishing is possible from the jetty at any time. The protected bay offers excellent fishing opportunities with a rowboat. The bay is large enough to also allow trolling with a rowboat. For fishing outside the bay, a motorboat is recommended to comfortably reach the more distant fishing spots. Access to the lake from the shore is only possible in a few places. The lake features a variety of underwater structures and drop-offs, which are especially well suited for fishing by boat. The lake bottom is partly rocky and sandy, with scattered aquatic vegetation. The many islands in Lake Puruvesi are easily accessible by boat and offer idyllic barbecue areas, swimming spots, and beautiful shallow bays perfect for relaxing and unwinding.

Resort Naaranlahti is located right by Lake Puruvesi, which is famous for its clear water (transparency 11.2 m, color of water 6 PtCo) and outstanding fishing possibilities. The Lake provides an excellent fishing environment with its scattered shorelines and numerous islands. It is is part of Saimaa and itself has an area of 320 km² of open water. Directly in front of the accommodation lies a bay with depths ranging from 1 to 2.5 meters, which is sparsely overgrown with aquatic vegetation. This bay gradually transitions into a deeper area reaching up to 4 meters, which then opens into the main lake where depths reach up to 30 meters.
