For those who want to paddle a little bit further our outer archipelagos provides great places for seakayaking. Places like Håkansskär och Vattungarna have great kayaking and camping on the cliffs. If you want to stay comfortable is the hostel on Fejan and their first-class skärgårdskrog that is your option. Another tour that requires an overnight stay goes north from Gräddö towards Arholma. There are hostels, one restaurant and things to do.
For the one that wants a slightly longer paddle Söderarm archipelago is offering several excellent tent rocks but one should keep in mind is to bring water for the whole tour, then it can be hard to come by on the islands.
