We watched this beautiful sunset from Tahina while anchored off the island of Nukunamo (mosquito island) in the Ha’apai group of islands in the Kingdom of Tonga. This was in October of 2010. The cone-shaped “mountain” is a volcano on the island of Kao – about 75 km away.
You can read more about our visit there in this post and the posts before and after it. Here’s a map showing the location of Tahina where the photo was taken, and the location of the volcano 75 km to the west.
