Tips for Visiting Bolshiye Peshnye Islands

  • These islands are ecologically sensitive - any visit requires coordination with Kazakh authorities and research permits.
  • Use satellite charts: water depths around Caspian islands can change and there are shoals unmarked on older maps.
  • Summertime sea-ice isn't an issue, but wind and sudden squalls on the Caspian can make small-boat landings hazardous.
