Hello, I'm planning a six-week visit to the Peloponnese next fall. My primary interests are ancient archeological sites and the towns of Nafplio and Monemvasia. I'm in my late sixties and have arthritic knees but am otherwise in good health and weight for my age. Having been on steep, uneven streets and archaeological locales the past two years in Italy, Spain, and Greece, I'm prepared for similar terrain in the Peloponnese. However, I'd very much appreciate advice and opinions about the ease or difficulty of traversing the following places. Up and down is difficult, but not impossible, for my knees, but flatter is easier. Thanks!
Corinth
Acrocorinth
Nemea
Mycenae
Epidaurus
Tiryns
Nafplio
Olympia
Bassae
Messene
Pylos
Sparta
Mystras
Monemvasia
