Henderson Island, a UNESCO World Heritage Site, is a remote and largely uninhabited island known for its exceptional biodiversity and unfortunately, significant plastic pollution. Access is extremely difficult, typically requiring a long sea voyage from Pitcairn Island and is highly weather-dependent. Due to its isolation and lack of facilities, solo visits are not recommended; guided expeditions are the only viable option, with costs varying greatly depending on the length and type of trip, potentially reaching thousands of dollars. There are no seasonal restrictions, but the austral summer (November to March) generally offers more favorable weather. A typical visit might last several days to a week, focusing on scientific research or environmental cleanup efforts rather than traditional tourism. Accessibility for those with mobility issues is severely limited due to the island's rugged terrain and lack of infrastructure.
