Vanuatu
Walk off a beach into a 200-metre sunken liner, hit by her own navy's mines.
You wade in from the shore, swim fifty metres, and the seabed falls away onto the hull of an ocean liner lying on her side in blue water. Corridors run into darkness below you. Somewhere inside, a porcelain lady and her unicorn still preside over the first-class smoking room.
Launched in 1931, the President Coolidge carried a gymnasium, a theatre, a ballroom and two swimming pools before the war stripped her into a troop transport. On 26 October 1942, entering Santo's Segond Channel with more than 5,000 troops aboard, she struck two of her own navy's mines; her captain drove her at the shore, and in the hour before she slid under, all but two men walked, climbed or swam to safety. Those two dead make her a war loss as well as a dive, and she is treated with that respect. The 200-metre wreck now lies between 21 and 70 metres on a slope beginning a short swim off the beach, inside the marine reserve declared over these waters in 1983. Ten to fifteen dives barely cover her holds, promenades and cargo; the deepest rooms belong to technical divers, and every route is planned to certification and conditions.

Solo
Join a local operator and let your certification and recent experience set the route; the upper decks alone repay a week of diving.
Couple
Book a series of progressively deeper dives and end each afternoon comparing which corridor, artefact or shaft of light stayed with you.
Friends
Split across skill levels, beginners on the exterior and trained divers deeper, and agree before descending that nobody follows the group past their limit.
Bombua Beach House, two kilometres from the wreck, plates lobster from local waters and poulet fish for the surface interval.
In Luganville, Lapita Lodge prepares traditional bunia or laplap for groups who ask ahead, the island's earth-oven cooking after a day inside a liner.

Abaiang
Kiribati
At high tide the sea surrounds Tebunginako's church; the village choir times services around it.

Abbotsbury
England
A swannery where six hundred mute swans nest in reed beds behind the Chesil Bank.

Abel Tasman National Park
New Zealand
Golden bays between forested headlands, reached only on foot, by kayak or water taxi.

Aberdaron
Wales
A church on the sand where pilgrims ate their last meal before the island crossing.

Ambae
Vanuatu
Every soul left Ambae twice when the volcano stirred; its crater lake still shifts colour.

Champagne Beach
Vanuatu
At low tide the shallows fizz: volcanic gas rising off the seabed named this beach Champagne.

Futuna Island
Vanuatu
The language changes mid-archipelago: Futuna is Polynesia, moored inside Melanesian Vanuatu.

Hideaway Island
Vanuatu
Post a waterproof postcard from the world's only underwater post office, then snorkel the sanctuary reef.
