The island of Upolu is part of Western Samoa and where all the admin stuff is. There are many wonderful things to check out, like the hole in the rock by the monastery, Robert Louis Stevenson´s house and grave, various waterfalls to jump in and most of the beaches. However, all the roads to the beaches are always patrolled by Locals and they demand some money before you can use the beach. In fact everything in Samoa needs money before it will work. Unless you can speak the language, (Samoan) everyone is distant.
