There are ferries between mainland Estonia and its many islands, Saaremaa, Hiiumaa, Kihnu, Ruhnu and Vormsi being the most frequented by visitors.
Praamid (www.praamid.ee) and Kihnu Veeteed (www.veeteed.com) are the major operators – check websites for exact routes and prices.
Estonian roads are generally very good and driving is easy.
In rural areas, particularly on the islands, some roads are unsealed and without lines indicating lanes, but they’re usually kept in good condition.
Winter poses particular problems for those not used to driving in ice and snow.
