Day 1 — Vecrīga: The Medieval Old Town
Start at the Freedom Monument, Riga's central symbol — completed in 1935, it survived Soviet occupation because Latvians treated flower-laying at its base as an act of quiet defiance, and the tradition continues today. From there, walk into Vecrīga through the Esplanade or straight down Brīvības bulvāris.
Doma laukums (Cathedral Square) is the Old Town's heart. Riga Cathedral is one of the largest churches in the Baltic states, with an organ that draws recital audiences from across the region. A few streets over, St. Peter's Church has the best viewing tower in the city — climb it for a full panorama of the Old Town's red roofs and the Daugava beyond.
Spend the afternoon getting lost deliberately: the Three Brothers (the oldest surviving stone houses in Riga, 15th–17th century), the Swedish Gate (the only surviving gate in the old city wall), and the House of the Blackheads, whose ornate facade was rebuilt after WWII destruction and Soviet-era demolition. Just behind it, the Riga Museum of the Occupation gives essential context on Latvia's Soviet and Nazi occupations between 1940 and 1991 — a sobering but important stop, and free to enter.
Evening: dinner in the Old Town, then a Riga Black Balsam at a bar near Doma laukums. If you want a longer night, the streets around Kalēju iela and Skārņu iela have a decent concentration of bars, though prices here run higher than elsewhere in the city.
Day 2 — Art Nouveau District & Central Market
Morning: walk north into the Quiet Centre (Klusais centrs) for Alberta iela, Elizabetes iela, and Strēlnieku iela — together they form the world's finest concentration of Jugendstil (Art Nouveau) architecture, with over 800 buildings across the city carrying the style. Mikhail Eisenstein designed many of the most extravagant facades: leering faces, sphinxes, owls, and floral ironwork covering entire building fronts. The Riga Art Nouveau Museum at Alberta iela 12 shows a restored period interior — worth the entrance fee.
Lunch in the Quiet Centre or walk back toward the Old Town.
Afternoon: the Riga Central Market (Rīgas Centrāltirgus), housed in five former German military zeppelin hangars converted into market pavilions in 1930. It's one of Europe's largest and busiest markets — separate halls for meat, fish, dairy, and vegetables, plus outdoor stalls selling everything from forest mushrooms to Soviet-era memorabilia. Budget at least 90 minutes and go hungry.
Evening: the Miera iela neighbourhood, about 2km from the Old Town, has Riga's best independent cafés, concept stores, and newest restaurant openings. It's the antidote to Old Town tourist pricing, and a good place to try a Latvian craft beer from Valmiermuiža or Tērvetes, the country's two leading breweries.
Day 3 — Jūrmala Beach Day Trip
Jūrmala is Latvia's principal Baltic Sea resort, a 32km strip of coast just 30 minutes from Riga by regular train (departures every 30 minutes from Riga Central Station). The wide sandy beach, dune-backed pine forest, and wooden Art Nouveau villas along the pedestrianised Jomas iela make it a genuinely different pace from the city.
Get off at Majori or Dzintari station — both put you a short walk from the beach and the main strip of cafés and restaurants. Walk the beach, then Jomas iela for lunch and a look at the resort's historic wooden architecture, some of it dating to the late 19th century when Jūrmala was a fashionable spa town for the Russian imperial elite.
Return to Riga by early evening for a final dinner in the Old Town — Latvian classics like rasols (a potato and beetroot salad with herring) or smoked fish are worth trying before you leave, alongside a last glass of Riga Black Balsam. If you'd rather stay in Jūrmala longer, the resort has a genuinely good spa-hotel scene, and dinner on Jomas iela is a fine way to close out the trip before catching a later train back for your flight the next morning.
