Raintsaari emerged from underneath the continental ice sheet during the Yoldia Sea phase around 11,300 years ago. A Stone-Age dwelling and cairn from the Early Metal Age have also been found on the island. The cairn is a fairly oval shape and consists of rather large stones on top of and around a smaller rocky mound. The cairn is 2.5-3.0m in diameter and half a metre tall.
Raintsaari is an island destination that can be reached by boat in summer. There is a pier for small boats on the western shore of the island and also a campfire site and an outdoor toilet.
