Riga by train: Art Nouveau and the old town

Riga is about four hours from Vilnius by train, so it suits a weekend. Visit the Art Nouveau Museum and Riga Cathedral, and walk along Alberta Street, famous for its Art Nouveau buildings. It suits autumn and winter. A weekend plan fits into two days: Saturday evening in the old town by Riga Cathedral, the next morning the Art Nouveau Museum and Alberta Street, and on Sunday the train back. Practical tip: the Art Nouveau Museum is open daily 10:00–18:00, with tickets sold until 17:45, and Riga Cathedral is open Monday to Saturday 10:00–17:00 and on Sunday 14:00–17:00, so go into the cathedral during the day on Saturday, before the evening in the old town.
