Audio Guide of Tytyri Caverns

Tytyri Caverns are open from Tuesday to Sunday, 10:00 AM to 5:00 PM during the summer season (June to August), with reduced hours in winter; it is recommended to check the official website for updates. To get there, they are located about 50 km from Helsinki, accessible by car via Road 110 or by bus from Lohja station; parking is free on site.

Adult admission costs around €18, with discounts for children (€10) and families (around €45 for two adults and two children); it is free for children under 6. Tickets can be purchased online to avoid queues at the official Tytyri website.

It is recommended to allow at least 1 to 2 hours for the main visit, which includes the underground tour and exhibitions. If you are a mining enthusiast, you could extend it to 3 hours by exploring the entire open-air museum.

Tytyri Caverns are part of a former dolomite mine that operated from 1897 to 1999, representing Finland’s important mining industry in the production of construction materials. Today, it is an underground museum that teaches visitors about the region’s labor and geological history, attracting those interested in Finnish industrial heritage.

The best time is during the summer (June to August), when the weather is warmer and there is more daylight to explore the outdoor area; avoid the winter months because of the underground cold. Visit early in the morning (around 10:00 AM) to avoid crowds and enjoy quieter tours.

The main underground tour is not wheelchair accessible due to stairs and narrow passageways, but there are surface areas adapted with ramps. It is recommended to contact staff through the official website or by phone (+358 44 374 4100) for alternative options or special assistance.

Nearby in Lohja, you can visit St. Lawrence Church, a medieval gem just 5 km away, or Lake Lohjanjärvi for outdoor activities. There is also Paavola Park with nature trails, ideal for a combined excursion; plan a full day exploring the region.

Bring warm clothing and comfortable shoes, as the underground temperature stays around 8–10°C; do not forget your camera for impressive photos of the rock formations. Book the tour in advance during high season through Tytyri.fi and consider combining it with lunch at the museum café for a complete experience.
