Valparaiso
Valparaiso is the most important seaport of Chile, and vital cultural center. Located in central Chile, it is capital of the Region of Valparaíso and home of the National Congress. Valparaiso boasts a labyrinth of streets and cobblestone alleyways upon steep hillsides overlooking the Pacific Ocean, with a very rich architectural and cultural legacy. It is considered one of Latin America's most intriguing urban areas, and it is protected by the UNESCO, who listed it as a World Heritage Sit
Self-called a "park of the imagination," this museum offers children and adults the chance to play and learn at the same time. There are guided tours led by staff members, whose duty is to engage visitors in learning by doing. Each visitor is encouraged to participate in the interactive exhibits. The museum originated with an idea by former First Lady Marta Larraechea de Frei, and it was one of her last achievements while involved with the government.
A peninsula gaves protection to this small beach from the coastal winds, making the waters stay quiet and safe for swimming. It used to be very popular before the ignaguration of the Reñaca resort, and it still receives a lot of visitors during summer time. It is a favorite of families with small kids. There are parking facilities nearby, and on the other side of the road is a fairly good selection of restaurants and shellfish bars, in case you're feeling peckish.
There are two main sections to visit at this museum, a natural history department dedicated to Chile's native fauna and flora; and an archaeological department offering a permanent display related to the indigenous peoples of Northern Chile, the Aconcagua region and the Mapuche in the south of the country. There is also one of the most important collections in the world related to Easter Island, including the only genuine Moai statue in the whole of continental Chile, outside in the museum garden. Guided tours are available in both Spanish and English so you can understand what you are seeing.

The dark-coloured sands, fine in texture and rich in volcanic minerals, gave the area its name (the black beach). Although this beach doesn't have the attractions of others, it is still a good place to spend you family vacation without preocupations. Despite its distance from the centre of Viña del Mar, the good public transport connections make it easily accessible for your convenience.
