All of Santiago's larger hotels have health clubs on the premises, usually with personal trainers on hand to assist you with your workout. Even if you aren't staying at a particular hotel, you can usually pay to use the facilities for the day.
Balthus. The city's top health club, this high-tech marvel has all the latest equipment. You feel healthier just by walking into the complex, a sleek series of riverside structures in concrete and glass. There are eight tennis courts, spas, pools, and numerous fitness programs. There is another location at Mall Sport, which is considerably farther from where most visitors stay. The day pass costs 37,000 pesos for non-members. Av. Monseñor Escrivá de Balaguer 5970, Vitacura, Santiago, 7630000. 2/2410–1414. www.balthus.cl.
