The best time to visit Chile depends on the regions you plan to explore. Generally, the summer months (December to February) are ideal for Patagonia and the Lake District, while spring (September to November) and fall (March to May) offer pleasant weather for central Chile and the Atacama Desert. Winter (June to August) is perfect for skiing in the Andes and whale watching along the coast. Consider your desired activities and destinations when planning your trip, as Chile's diverse geography results in varied climates throughout the country.

Most tourists from North America, Europe, and many other countries do not need a visa to enter Chile for stays up to 90 days. Upon arrival, you'll receive a tourist card (Tarjeta de Turismo) that must be kept with your passport and presented when leaving the country. However, it's always best to check the latest visa requirements with the Chilean embassy or consulate in your country before traveling, as regulations may change and some nationalities may require a visa.

In most urban areas of Chile, including Santiago, the tap water is generally safe to drink. The country has a well-developed water treatment system, and the quality of tap water meets international standards. However, in more remote areas or smaller towns, it's advisable to drink bottled water or use water purification methods. If you have a sensitive stomach or are unsure about the water quality in a specific location, it's best to err on the side of caution and opt for bottled water.

Chile offers a diverse range of must-visit destinations. The Atacama Desert in the north is known for its otherworldly landscapes and stargazing opportunities. Santiago, the capital, blends modern city life with rich history and culture. The colorful coastal city of Valparaíso is famous for its street art and vibrant atmosphere. The Lake District offers stunning scenery and outdoor activities. Patagonia, including Torres del Paine National Park, is a paradise for nature lovers and hikers. Easter Island, though remote, is worth visiting for its mysterious moai statues and unique Polynesian culture.

Chile has a well-developed transportation system. For long distances, domestic flights are the most efficient option, with several airlines operating between major cities. Buses are a popular and affordable way to travel between cities, with comfortable and reliable services available. In urban areas, public transportation includes buses and metro systems (in Santiago). Renting a car is a good option for exploring regions like the Lake District or parts of Patagonia, but be aware of the long distances and varying road conditions. In major cities, ride-sharing apps and taxis are readily available for local transportation.
