Guided outings in and around Tandil: the town's landmarks including the Cerro La Movediza, where the famous rocking stone balanced until 1912; panoramic drives in the sierras; rural visits; a route through the local cheeses and cured meats; and a walking tour of the old frontier town.
The WhatsApp is the one Tandil's municipal tourism site gives for them. They publish no office; the pin marks the town centre.
