The Time Trek is a 13.7 kilometer long trekking and outdoor route that starts at the Tuorla Observatory and ends at the University of Turku. The Trek passes through the cities of Kaarina and Turku and is designed for all those who are interested in the history of the Universe, Earth and Life. The Trek is designed for people of all ages, and should be interesting for the whole family. The scenery along the Trek is diverse ranging from forests, fields and parks to urban environments.

The length of the Trek, 13.7 km, is intended to reflect the Universe's age, 13.7 billion years. This can be seen along the Trek as one kilometer equals to a billion years in the age of the Universe. There are Rapakivi-boulders with brass plaques along the route marking out significant points in the history of the Universe. The plaques will briefly explain the events marking a certain period. Some of the words used on the plaque might be difficult to understand, so we recommend you take with you the free brochure, that is available on this website, that includes the map and glossary.

The Time Trek is designed so that you don't have to walk all 13.7 kilometers at once. You can familiarize yourself with the latest 1800 million years of history just in Turku. There are also places to sit down and rest, as well as cafés and restaurants along the route. These are, for your convenience, also marked on the map.
