Tips for Visiting Tiwai Island #
- Arrange entry and guided visits through the Tiwai Island Wildlife Sanctuary or an authorised operator before you travel-the island operates as a managed research and conservation area and access is controlled via boat from nearby river towns.
- Visit in the dry season (roughly November-April) when river conditions are easier for boat transfers and wildlife-viewing walks are more reliable; staying at the on-site research/lodge facilities improves your chances of guided night and dawn wildlife sightings.
Best Time to Visit Tiwai Island #
