There are loads of things to do in Solomon Islands. There are active volcanoes, WWII wrecks, ancient villages to explore and people of various cultures to interact with as you travel across the country.
Being an archipelago, all the popular activities are in and around the ocean. There are many coral atolls in the region, making it a perfect place for snorkeling. Hundreds of sites are scattered all over the longest lagoon in the world, where you can snorkel and take in the beauty of the corals. If you want something more adventurous, you can scuba dive to wrecks and watch rays in their natural habitat. You can also go kayaking or take a lazy swim near the coast.
If you are bored of water activities at any point, there are other exciting activities that you can participate in. The Kolombangara is a perfect cone of a volcanic mountain where you can climb up to the rim, view the crater and get some jaw dropping views of the area from the top. There are a number of other hiking and trekking trails that dot the country.
Otherwise, you can go for organized walks. These walks cover villages, markets, parks and other areas of interest that are beautiful, vibrant and brimming with life in all forms. You can also visit lakes and waterfalls hidden among the mountains and volcanic craters.
