The listing called Mikri Asini Beach corresponds to the small beach of Ancient Asini, also known locally as Kastraki, beside the archaeological promontory east of Tolo. The Municipality of Nafplio describes a compact pebbled shore with rocky edges and a rocky-pebbled seabed. Its scale is intimate, but the neighboring acropolis gives the swim an archaeological setting found at few beaches in the Argolid.
Municipal visitor information records access on foot from the Tolo area or by car, with free parking, a café, showers and seasonal rental umbrellas and loungers. Those services should be verified on arrival because concessions are seasonal. The rocky bottom and deeper water favor confident swimmers and careful snorkelers; water shoes are useful, and families should assess conditions rather than assume a sheltered-looking cove is risk-free.
