Give a full day to Aspronisia, Makronisi, Arki and Marathi without confusing a swim stop with knowing an island
This boat day reveals the archipelago around Leipsoi rather than merely circling its coast. Typical routes include the bright stones of Aspronisia, sea caves at Makronisi, Tiganakia's aquamarine shallows and short calls at Arki or Marathi. Wind and vessel conditions decide the actual order and whether a stop is safe.
Ask about shade, swimming access, lunch, cash and flotation equipment before booking. A brief harbour call does not represent daily life on Arki or Marathi, so spend thoughtfully and avoid photographing residents as scenery. Use a licensed operator and accept route changes without pressuring the crew.
