Falealupo Rainforest Preserve

This lava cave is in the north close to Letui village and a ten-minute walk from the road. A guide can also be easily found, which is essential as the entrance to the cave is locked.This cave is home to hundreds of white rumped swiftlets. The 'clicking' noise of the birds is clearly audible as they fly in the dark.

This cave is over a kilometre long. he legend is that this cave is home to a race of small people. The legend has never been disproved as the end of the cave has apparently never been reached. Exploring the cave can take almost an entire day. A guide from Paia village is essential.

You will have to walk three hours from Paia village to visit these lava fields that look like a barren moonscape. They were caused by the eruptions of the mountain between 1905 and 1911.

Lava flows created a series of tubes connecting the cliff top with the ocean. Waves send water at high pressure through the tubes, creating fountains. The rocks can be quite slippery, so make sure to take appropriate shoes with you. Also beware of tourist traps in this area - the guides here might ask you to take photos as they throw coconuts into the blowholes and then demand money from you afterwards. They can be very persistent, but just maintain your distance and say no.

These were also caused by volcanic eruptions of Mt Matavanu in central Savai'i. The lava flowed over 40 square miles to the sea and destroyed Sale'aula and Salago villages. The depth of the lava is up to 400 feet. Sale'aula fields are much more accessible than the Mt. Matavanu fields. You will need a guide if you want to visit the two churches that avoided complete destruction as well as the grave of a Catholic nun, known as the Virgin's Grave, that escaped destruction. A fee is charged.

This is the largest ancient structure in Polynesia, with a base of 60 m by 50 m and 12 m tall.
