This park is 6km south of Tandil, at the end of Calle Suiz, off Av Don Bosco. The rocky hills are fun to climb, and in spring the reserve is filled with fragrant wildflowers. The peaks offer views of the town to one side and the patchwork pampean farms stretching out from the other. A somewhat incongruous collection of animals – llamas and donkeys among them – have free run of the park, while their natural predator, the puma, is sadly caged. Taxis here cost around AR$40 one way; arrange pickup for a return ride.
