Riga is the capital of Latvia and Riga is the important seaport and major industrial, commercial, cultural and financial center of the Baltic Sea region. Riga is the largest city in the Baltic states, and one of the largest cities in Northern Europe. A popular offbeat attraction on a city break holiday in Riga is a boat trip on either of the Riga city waterways. The Daugava River boat trip can be taken all the way to the Baltic coast and the seaside resort of Jurmala. Boats embark from the docks near the Akmens Bridge at Riga Castle in the Old Town. They run hourly from May to September. Daugava River trips usually pass under all of the major Riga's bridges including the Cable Bridge, the Railway Bridge, the Stone Bridge and the South Bridge.
