Naissaare Marina (Saarte Liinid AS)

Naissaare Marina sits on Naissaar island, a wild and largely uninhabited former Soviet military island that makes this one of the most atmospheric marina stops in the Gulf of Finland. You can tie up here between May and September, with showers on site and fuel available for topping up. Once ashore, the island's dense pine forests, abandoned gun batteries, and near-total quiet are yours to explore — it's genuinely unlike anywhere else on the Estonian coast.
