The capital city is situated on the Bay of Asunción, an inlet off the Paraguay River. Planned on a colonial Spanish grid system, it has many parks and plazas. On the way to the waterfront the visitor enters the old part of town, an area of architectural diversity. A good view of the city can be had from the Parque Carlos Antonio Lopez high above Asunción. The Botanical Gardens are situated in a former estate of the Lopez family on the Paraguay River. There is also a golf-course and a small zoo. The Lopez Residence has been converted into a natural history museum and library. Package trips can be booked to see the Iguazú Falls and the Salto Crystal Falls, and river trips to Villeta or up the Pilcomayo River to the Chaco. Luque, near the capital, is the home of the famous Paraguayan harps.
