Bicycle travel · Estonia

Hello fellow cycle-tourers! First post on this site for our first big family cycling adventure with our two teens (12 and 16 years old) over 2 months. We're preparing to leave in June/July from Erdeven by bike, then take the train from Auray to Paris, followed by a FlixBus from Paris to Copenhagen with our 4 bikes. After that, we're looking to refine our route: Should we go to Sweden via Helsingborg and then head up to Stockholm along the west or east coast? Maybe passing through the Gotland islands, then via the Åland Islands, why not Turku? Then off to Estonia to Tallinn, ride a bit along the coast, and return by bus if we can find one that takes 4 bikes. :))

Could you share any tips on routes in Sweden: west coast or east coast to prioritize in the south? We’ve heard it’s a shame not to go up to Norway, but we’re worried about the elevation and don’t see how to make a loop work in our 2 months / 1500 km. Any ideas? And the southern Finnish coast: should we go all the way to Helsinki or not? Maybe at the expense of Estonia?

In short, we know choosing means giving something up, but if we can do it with advice from fellow cyclists, that would be amazing! Thanks in advance for your tips! Anne-Sophie and the whole Breton family: David, Axel, and Maude
