Mount Yasur on Tanna stands 361 meters above sea level and erupts multiple times per hour. Visitors drive to within 150 meters of the crater rim on most days, though access closes during heightened volcanic activity measured by the Vanuatu Geohazards Observatory. The volcano produces Strombolian eruptions—lava fountains and ash clouds that remain visible from the eastern coast of Tanna after dark. Local families from the Yakel and Imanaka villages hold customary ownership of access routes, and entry requires payment to these communities plus the standard park fee. The volcano sits within an ash plain that eliminated most vegetation within a two-kilometer radius. Tour operators depart Lenakel in late afternoon for sunset viewing, though the 90-minute drive on unpaved roads can extend longer after rain. No physical barriers exist at the crater rim.
The SS President Coolidge lies in 21 to 70 meters of water off Espiritu Santo's Segond Channel. This 200-meter luxury liner struck US mines on October 26, 1942, while serving as a troopship. The captain deliberately beached the vessel to allow evacuation—all but two of approximately 5,440 personnel survived. Divers enter the wreck through the promenade deck at 21 meters or descend to the engine room at 45 meters and the cargo holds beyond 60 meters. The ship rests on its port side with jeeps, rifles, gas masks, and medical supplies still secured in lower decks. Allan Power first documented the wreck for recreational diving in 1969. Espiritu Santo dive operators run daily trips, with most requiring Advanced Open Water certification for deeper penetrations. The wreck continues to degrade—the stern broke away in 2014.
Chief Roi Mata's Domain comprises three sites on Efate: Mangaas, the chief's residence; Fels Cave, where he died around 1600 CE; and Eretoka (Hat Island), his burial ground. Garanger's team uncovered Roi Mata's skeleton surrounded by approximately 50 retainers buried alive as part of the funeral ceremony—the bodies showed no signs of struggle, suggesting voluntary or drugged participation. The burial site remains closed to general visitation, though community-led tours reach Mangaas and Fels Cave with advance permission from the Nakamal Council. The domain covers 148 hectares across the three locations. Oral traditions credit Roi Mat with establishing peace between warring clans through strategic marriages and land distribution systems still referenced in property disputes today.
Pentecost land diving occurs annually between April and June when the vines used for ankle restraints reach peak elasticity from seasonal rains. Men construct wooden towers reaching 20 to 30 meters, then dive headfirst with liana vines tied to their ankles. The vines measure precisely to allow the diver's shoulders to brush cleared soil at the bottom—this contact supposedly transfers the diver's strength to fertilize yam crops. The practice originated in southern Pentecost at Bunlap and Lonorore villages. Queen Elizabeth II witnessed a demonstration in 1974, and A.J. Hackett cited land diving when developing commercial bungee jumping in New Zealand during the 1980s. Each tower supports multiple divers in a single ceremony, with boys as young as seven performing from lower platforms. The ritual faces declining participation—only four southern Pentecost villages maintained active jumping sites as of 2019. Some communities now stage demonstrations during off-season months using artificial materials, which traditional practitioners reject as spiritually invalid.
Espiritu Santo's Millennium Cave extends 30 meters high through limestone karst. The through-canyon route covers approximately 10 kilometers beginning at Funaspef village, requiring river crossings, boulder climbing, and swimming through pools before emerging at a second village. The cave system formed over several million years as the Rogovotu River cut through uplifted reef limestone. Funaspef families discovered the cave's full length in 1999 and began guiding tourists in 2000. Visitors descend 20 meters into the canyon by rope, wade through the river, and climb a 30-meter banyan tree root system to exit. The route passes under a skylight where sunlight penetrates the canopy. Tours require four to six hours depending on fitness and water levels. Heavy rain closes the cave due to flash flood risk.
The blue holes scattered across Efate and Espiritu Santo are freshwater springs emerging from underground limestone aquifers. Matevulu Blue Hole on Espiritu Santo reaches 30 meters deep with water maintaining 23 degrees Celsius year-round regardless of air temperature. The intense blue color results from limestone particles suspended in water refracting sunlight. Local landowners manage access, collecting entry fees typically between 500 and 1,000 vatu. Nanda Blue Hole near Port Vila includes a rope swing used primarily by children from nearby villages. None of these sites employ lifeguards or safety equipment. Riri Blue Hole on Espiritu Santo connects to the ocean through underground passages—divers occasionally enter from the ocean side during low tide, though narrow restrictions make this route dangerous.
