A 15-minute cable-car ride from Acevado metro station leads to the rural enclave of Santa Elena, where you’ll find Parque Arví, the country’s largest nature park. Within this wild and thickly forested landscape, you’ll likely come across cowboys on horseback or farmers herding their cows, sheep, or goats. There are walking trails that crisscross pine and eucalyptus forests, with more than 700 species of flora and fauna, as well as six núcleos (themed recreational zones): Núcleo Comforma has a zipline, playground, and musical garden; Núcleo Comfenalco features a nature trail, a hotel, butterfly house, a farm, insectarium, and camping/picnic areas. To fully explore the park, you’ll need to allow a full day here. Bikes (available for rent at the entrance) are an expedient way to explore the far-flung reaches of the park.
