Vanuatu allows visitors to stand at the rim of Mount Yasur's permanently erupting crater on Tanna, witness the Pentecost land-diving (the original bungee), and dive WWII wrecks off Espiritu Santo.
Dry season with Pentecost land-diving April-June, Tanna's Yasur volcano accessible, and Espiritu Santo's Million Dollar Point and SS Coolidge wreck diving at peak visibility.
National Day July 30 brings traditional ceremonies and dance, and the Independence Day events fill Port Vila's Independence Park with kustom dance from outer islands.
Wet season with cyclone risk peaking January-March, but Yasur remains accessible and the rates drop sharply across Port Vila and Santo lodges.
Late dry season with Yasur eruption activity at year-best photographic condition and the diving on Espiritu Santo at maximum visibility.
