The Wild Edge of Melanesia

A World
Apart,
Still
Untouched.

Papua New Guinea is the most culturally diverse country on earth — more than 850 languages spoken by 5,000 clans across volcanic mainland, coral atolls, and outlying island groups. For travellers who want a place that has not been smoothed for visitors, PNG remains as raw and as welcoming as anywhere in the Pacific.

Best reached by private yacht, where each anchorage is your own and each village welcome unhurried. The Coral Triangle wraps the country in some of the richest marine biodiversity on the planet, and the volcanic geology — flooded calderas, black-sand beaches, and Pacific Rim peaks — runs the length of the route.

This second expedition of the Melanesia Traverse begins in Alotau on the eastern tip of the mainland and threads north through Milne Bay, the East New Britain Baining country, the diving waters of New Hanover and Kavieng, and finishes in Manus Province at Lorengau. Rob McCallum, who grew up here, leads.

The Voyage,
Region by Region.

01Leg One
1 – 7 Nov
1 – 7 November · 7 Days

Eastern Milne Bay

Alotau → Conflict Is → Panapompom → Engineer

The voyage begins in Alotau on the eastern tip of PNG. South into the Conflict Islands — a vast sheltered lagoon ringed by coral cays and an active turtle nursery. Onward to Panapompom for the sailau canoes, the last working traditional ocean-going sail tradition in this part of the Pacific, then quiet days at Bonvouloir, Hastings, and the remote Engineer Islands before a port call back at Alotau to pick up additional guests.

02Leg Two
8 – 10 Nov
8 – 10 November · 3 Days

The Papuan Coast

Bogoboga → Tufi → Tami

North along the Papuan mainland. Bogoboga — an EYOS secret — for the sing sing, where local communities gather in full regalia to perform dances rarely seen by visitors. Then Tufi's drowned-river fjord country and the outer bommies, and the coral atolls of the Tami Islands off the Huon Peninsula.

03Leg Three
11 – 13 Nov
11 – 13 November · 3 Days

New Britain

Witu → Lassul · Baining

Two days inside Witu's flooded caldera — village hike to the rim, black-sand beachcombing, diving in the inner anchorages. Then east to Lassul Bay and Talele for the Baining Fire Dance — masked dancers leaping through burning embers, the quintessential PNG ritual.

04Leg Four
14 – 21 Nov
14 – 21 November · 8 Days

New Hanover · Manus

Kavieng → Emirau → Tingwan → M'Buke → Lorengau

World-class diving and snorkelling at Kavieng and across New Hanover — coral walls, channel passes, and Clem's place for an authentic island stay. Then north to Emirau and the St Matthias Group, west across the Bismarck Sea into Manus Province for Tingwan, Patuam, the WWF conservation reef at M'Buke, and disembarkation at Lorengau.

Knowledge Across the Voyage

Four Threads
Through Melanesia.

Thread 01
Live Calderas
& Volcanic Coast.
Witu's flooded caldera — a village living on the rim of a sleeping volcano. Two days inside the crater for hike, dive, and the black-sand beaches that built it. The Pacific Rim geology runs the length of the route: Tufi's drowned-river fjords, Rabaul's smoke on the horizon, and the volcanic islands strewn off New Britain.
Thread 02
Indigenous
Culture.
PNG is the most culturally diverse country on earth — more than 850 languages spoken by 5,000 clans. The Baining Fire Dance, the secret sing sing at Bogoboga, the mud men, the sailau canoe builders, the village welcomes at Emirau and M'Buke. Living cultures, rarely photographed, rarely seen by anyone who didn't arrive by yacht.
Thread 03
Sailau
& Sea Tradition.
Panapompom's sailau canoes — the last surviving traditional ocean-going sail tradition in this part of the Pacific. Watermen who can still build, rig, and race the boats their grandfathers sailed for trade across the Louisiade Archipelago. Two days at Panapompom to settle into the rhythm of the men who carry it.
Thread 04
Diving
& Reefs.
PNG sits at the heart of the Coral Triangle — the richest marine biodiversity on the planet. World-class walls and channel passes at Kavieng and New Hanover, soft coral and outer bommies at Tufi, the WWF conservation reef at M'Buke. Diving and snorkelling that defines the route end-to-end.

"Visitors leave Papua New Guinea humbled by the warmth and sincerity of the welcome, and profoundly affected by witnessing cultural ceremonies and ways of life that are disappearing in the modern age."
