In the middle of the San Isidro business district, El Bosque El Olivar is a 23-hectare grove of olive trees descended from Spanish saplings planted in 1560. Once a working estate that produced the olive oil for colonial Lima, it became a public park in 1959 and is now one of the most pleasant open spaces in the city.
Footpaths wind between gnarled, sometimes massive trunks under a high canopy. Joggers and dog walkers use it from dawn; in the evening the park fills with families and couples. The Iglesia de la Virgen del Pilar at the southern edge is one of San Isidro's small landmarks. Free, open all day, ringed by some of the most expensive houses in Lima.
