💡 Local Tip
Frequent visitors know that seaplane baggage limits are strict and the transfer can be wet, so pack compact, waterproof gear and keep essential items in a dry bag. Also, always ask local guidance before visiting reefs, beaches, or cultural sites, as access protocols vary.
🚖 Getting There
Getting to and from the seaplane base is usually arranged through your seaplane operator or local community contacts, as there is no public transport at the site.
