There are several camping sites throughout the Southern Peloponnese; contact the EOT for a free camping guide.
Throughout the Peloponnese there are many small trails, or kalderimi (mule paths), to explore, as well as the international E4 European Rambler Trail, which starts in the Pyrenees, winds through Eastern Europe, and traverses Greece to Gythion. The southern half, from Delphi to Gythion, is considered less difficult than the northern section and can be walked most of the year; the best time is mid-May through early October. Pick up the southern section at Menalon Refuge and continue through Vresthena, Sparta, Taygettus Refuge, and Panagia Yiatris monastery to Gythion.

Sailing in Greece isn't restricted to the Aegean Islands. Many people prefer to sail to the islands near Methoni, with stops at Sapientsa, Skiza, and Venetiko. When you rent a sailboat or charter a yacht, the agency will usually indicate where to find water and fuel. The local port authority can give information on sailing. You can moor at Gythion, which has water and fuel; in Kalamata repair service and moorings are usually available; for sailing around the Messinian cape, the port authority at Pylos can be of help.
