The museum garden has three basic purposes that make it another space of attraction:
- An information and training function for the visiting public so they can learn about or recognise the species of the region in their different environments, and at the same time a programme of guided tours to enhance understanding of the natural areas of the municipality and its environs, complementing the discourse on wellbeing and health started in the Balvey Pharmacy.
- An educational purpose, with a program aimed at school groups, a very clear tour, supplementary teaching materials and workshops.
- A leisure purpose with spaces (square and terrace) designed as rest areas, which can give a new purpose to the garden as a public park independent from and complementary to the museum. The garden hosts summer concerts and activities are held in July.
