The East Coast Road
Santo's East Coast Rd between Luganville and Port Olry is only the second sealed road in Vanuatu (completed around the same time as the Efate Ring Rd in 2011), so it's an ideal region for a day trip. But with some excellent places to stay, play and dine, it's worth setting aside a few days.
Ambae formed as part of a dramatic semiactive shield volcano, Mt Lombenben (1496m), which rumbles dynamically. A cone rose out of blue Lake Manaro Lakua, one of its famous crater lakes, in 2005, creating world news, then went back down. Hot and lime-green Lake Vui also sends volcanologists into a frenzy whenever it boils.
