With ferries running every 15 minutes to the fortress you don't have to wait very long. There's lots of stalls selling fresh berries, local crafts and souvenirs or you can grab a bite to eat from one of the many eateries in Market Square where the ferry leaves from and returns. With seating outside or inside, you get a nice scenic view for the short 15 minute ride. You don't have to pay an entrance fee to visit, you only pay for the ferry ride which is about 5 Euros and can get tickets at machines before you catch the ferry, tickets are not available onboard. As we were using other public transport we purchased a daily ticket for 8 Euros which gave us unlimited use on buses, trams, trains and the ferry. We picked this up from a kiosk near our hotel.
We spent a few hours walking around the old fortress which is home to 800 residents. Following the Blue Route, walking around this World Heritage site we come across relics from its time as a fortress - cannons, old ammunition stores and former barracks. There's also a few museums which we didn't visit. There's also lots of parks and grass areas to enjoy. We stopped at the local craft brewery, Panimo Brewery, on our way back to the ferry, it also sells food and other cafes across the area sell food and drinks also. There's a lot of walking involved, a lot of times on uneven ground so sensible shoes are a must.
It's a really nice scenic outing for a few hours and would recommend a visit.
