TIP FOR ROUTE PLANNING FOR THE GREAT ARCHIPELAGO RING ROUTE in a clockwise direction:
A possible route plan for the Great Archipelago Ring Cycle Route starting from Turku in a clockwise direction can consist of 4-5 day sections (depending on fitness). If campsites are used, here is a possible suggestion:
Day 1: Because I was coming from Helsinki, I drove 23 KM or around 1:20 from Turku to Camping Solliden (solliden.fi/) in Pargas/Parainen
Day 2: Camping Solliden to Camping Kittuis (kittuiscamping.fi/) is around 64 km or 4 hours.
Day 3: Camping Kittuis to Camping Livonsaari is 90 KM or 5 hours (livonsaarencaravan.fi/).
Day 4: Camping Livonsaari to Turkku is around 40 km or 2.5 hours on the last day - then you can also travel back to Helsinki
An alternative campsite for day 4 would be a campsite in Mussalo, which would have shortened day 3 a bit (sfcmussalo.fi/)
Of course, you can also spend the night in nature in Finland with the right of public roaming (Jokamiehenoikeus). However, you have to follow certain rules. visitfinland.com/en/articles/finnish-everyman-rights-the-right-to-roam. The hours given are purely driving times.
