Welcome to the Nordic region's longest narrow-gauge railway between Hultsfred and Västervik. Smalspåret is a living museum showcasing the railway journey some 40–50 years ago. In the summer, both steam trains and railbuses roll along the tracks, with booked tours for groups available year-round. Designated by the Swedish National Heritage Board as one of the country's most interesting industrial monuments, the railway traverses scenic landscapes, alongside lakes and past steep mountains.

Cheong Fatt Tze, the Blue Mansion, was one of the wealthiest merchants of the 19th century, and Penang Straits Settlement imported artisans from China to build this opulent 38-room mansion. With its five courtyards, carved woodwork, Gothic louvered windows and cast iron, the mansion is a fascinating fusion of East and West culture. The building was restored at a cost of 7.6 million ringgit, and it is crammed with sculptures, antique furniture and tapestries, while now being a unique boutique hotel. However, it is also open for non-residents during guided tours, so book one ahead.

Check out the magnificent caves at Puente Viesgo (24 kilometres from Santander), where stalactites and stalagmites stretch among incredible prehistoric paintings. The village itself is also worth a look around. Tours start at the visitor centre 1.5 kilometres above the village.
