The park's soil is formed from the basaltic lava flows of the nearby Croscat volcano.
It houses the Museu dels Volcans, which features a permanent seismic simulator for earthquakes occurring in the region.
The 'roureda' (oak grove) at Parc Nou is one of the best-preserved examples of Quercus robur woodland in the entire Iberian Peninsula.
The garden was originally a private estate belonging to the Trinxeria family before it was acquired by the municipal council.
The park contains a specific area dedicated to the cultivation and exhibition of medicinal and aromatic plants.
Parc Nou is a 1.7-hectare botanical garden located in the Garrotxa Volcanic Zone, renowned for its diverse collection of centennial oak trees, specifically the deciduous oak (Quercus robur). The park serves as an educational center, housing the Casal dels Volcans, which provides information on the region's geological activity. It features a unique microclimate that supports flora typical of central Europe, which is rare in this part of Spain. The garden layout integrates natural volcanic terrain with structured botanical displays, including a pond and various indigenous plant species. Visitors can explore a marked path that showcases the transition between forest and grassland ecosystems. The grounds are maintained as a protected natural space, emphasizing the conservation of local biodiversity. It is one of the most significant green areas in the town of Olot, acting as a habitat for local bird species and small mammals. The park includes an original neoclassical-style farmhouse that adds historical architectural value to the landscape.
