The Blue Lagoon is without a doubt the most well-known geothermal spa in Iceland. The signature milky-blue water makes a stark contrast to the surrounding black lava fields and creeping grey moss. The spa is located in a lava field near Grindavík and is supplied by water used in the nearby Svartsengi geothermal power plant. The water temperature stays at 39°C year-round, snowfall or sunshine. Most visitors make the spa their first or last stop, since it's conveniently located only 15 minutes from the Keflavík International Airport (and around 30 minutes from the capital city). If you are buying a tour, it makes most sense to combine the spa visit with the Golden Circle day trip.

The Pier of Burgas, stretching nearly 300 metres into the Black Sea, is a defining feature of the city’s coastline. Originally constructed in 1936 and revitalised in 2013, it features a 22-metre-high viewing platform and serves as a departure point for boat trips to Saint Anastasia Island. A popular spot for leisurely walks or morning runs, the Pier also hosts the annual Epiphany cross-throwing ceremony, blending natural beauty with cultural tradition.

Documenting Latvia's history and literature, hosting exhibitions and simply an architectural masterpiece, the Castle of Light, or National Library of Latvia, is worth a visit if only to be admired for its striking design.

Nessebar, a city-museum and UNESCO World Heritage Site, is another marvellous day trip from Burgas, located just 35 kilometres away. This ancient town, often called the "Pearl of the Black Sea", sits on a small peninsula connected to the mainland by a narrow causeway, offering stunning sea views on both sides. Its cobblestone streets wind through a historic centre filled with over a millennium of architectural treasures, including the Church of St. Sofia, a 5th-century basilica, and other medieval churches like St. John the Baptist and St. Stephen. The Old Town, a maze of narrow lanes and 18th-century houses, invites leisurely exploration, with artisan shops and street vendors adding to its charm. Nessebar was once a Thracian settlement and later a Greek colony, playing a key role in the development of trade and culture in the Black Sea region. Its unique blend of ancient ruins, Byzantine churches, and a lively atmosphere makes it a captivating destination for history enthusiasts and casual vacationers.
