Responsible travel & marine conservation

The Mafia Island Marine Park (MIMP) is central to conservation in the region — protecting coral reefs, mangroves and endangered species. Tourism fees support reef health and sustainable fishing practices, and licensed operators enforce reef-safe guidelines and respectful whale-shark encounters to minimise impact on wildlife and habitats.

Practical tips

  • What to pack: Reef-safe sunscreen, snorkel gear (or rent locally), water shoes, wide-brim hat, quick-dry clothing and underwater camera.
  • Health & safety: Follow guide briefings for marine activities; respect minimum distances around whale sharks.
  • Cash & services: ATMs are limited on the island, and many local vendors accept cash only — bring Tanzanian Shillings.
  • Respect culture: Mafia communities are predominantly Muslim — modest dress away from beach areas is appreciated.
