On the guided tour, you will learn the fascinating story of the old and abandoned industrial adventure in Osa. The 100-year-old tunnels have several different shafts and tunnels, all with different levels, which you can walk in.
The tour includes a visit to the historic cafe inside the mountain, where you will be served coffee and pancakes. The tunnel is currently privately owned and can only be visited with a guide. The trip lasts a maximum of 1.5 hours and is suitable for all ages. Included in the price, B-Active will provide you with a helmet and torch.
