'Eua Island is located only 17.5km east-southeast from Tongatapu. It is the highest island in Tonga and is not related geologically to the other islands, being much older. It has beaches on the western side but dramatic cliffs on the east coast, with Tonga’s largest tropical rain forest, which is a great place to go trekking.
‘Eua is just an eight-minute flight from Tongatapu on Chathams Pacific Airline . There is also a ferry that leaves from Nuku’alofa at 10.30 in the morning on Tuesdays, Wednesday, Thursdays, Fridays and Saturdays. Keep in mind that the ferry may leave earlier or later than scheduled, so arrive well before transit (this is the only way to know for sure if the ferry is leaving) Cost is T$23. The ferry can get rather crowded, so be early. On average, the ferry will take about two and a half hours, but can take much longer (5-6 hours!) in poor weather. Note that flights and ferries can be delayed or even cancelled without notice in poor weather conditions.
The ferry leaves from the 'Eua wharf at 4.00 pm in the afternoon on Tuesdays, Wednesday, Thursdays, Fridays and Saturdays. There is no return service to Tongatapu on Sunday and Monday.
There is no public transport within 'Eua, but it's easy to walk in the main village. And to the other villages on the island.
There is only one place on the island where beer can be bought from a licensed seller. The house is located across the street from the Catholic church on the south side of town just past the village of Pangai. On a road going west from the main road it will be the second house on your left (there will be signs). They sell out of their garage, and they only sell Maka beer for T$3.50. The locals will be able to help you find your way if you get lost.
