Landscapes in Australia and Pacific
Right below the Toula Village lies this cave pool. The water is brackish and refreshingly chilled. Nobody knows where the springwater comes from. You can take a swim in the dark pool, which isn't particularly deep (max 2 m). Sadly, there are some trash floating around, which makes a dip less inviting.
Funafala is the second biggest islet in the Funafuti Lagoon and one of the few inhabited islets. There are about 15-20 people living there, among a church and many picturesque coconut palms. At the time it's not possible to stay here, but you can swing by while on a boat trip in Funafuti Lagoon.
Wow! Standing on the rim of an active volcano when it suddenly erupts aggressively is a not-to-be-missed experience in life - that is, if you survive the flying lava. Mt. Yasur on Tanna island is the perfect volcano for that. It is active big time and the crater can easily be reached by foot or even 4WD. At daytime, it is a rather impressive sight with smoke, bangs and flying rocks heading for the sky, but it is nothing compared to the real show at night time. Red hot lava is thrown into the air, changing shape, and landing (hopefully) on the inner side of the crater. If the activity is not too intense, you can even climb the higher rim on both sides of the greater crater and look straight down into the flaming center (there are four crates within the one volcano). Tourists have been killed by venturing too close, so listen to any advice from the locals.
