What's the must-see thing in Lima?

The museum sits about 25 minutes by taxi from Miraflores. Rafael Larco Hoyle built the collection to roughly 45,000 objects, housed inside an 18th-century colonial building with thick white walls that keep the galleries cool. The courtyard garden smells like warm earth and flowering bougainvillea even in August. You'll spend about 90 minutes in the chronological rooms. The Moche portrait vessels, dated to around 100-700 AD, are the highlight. These are individual human faces, not stylized gods. They stare back with specific expressions. There is a back gallery of explicitly sexual ceramics that catches most visitors off guard. Admission costs 35 soles, about $10 at the current rate of 3.38 soles per dollar. Afterward, the Café del Museo sits in the courtyard garden under thick bougainvillea and serves a lomo saltado for around 38 soles.

Plaza Mayor earns a top-three slot not for any single building but for the density of colonial architecture within a 4-block radius. The Cathedral of Lima has occupied the east side since 1535. The Government Palace fills the north face, where a changing-of-the-guard ceremony happens at noon with a brass band you can hear from the surrounding streets. The square smells like pigeons and street-cart churros. To be fair, the cathedral interior is modest compared to Cusco or Arequipa. Dim, cool, heavy with dark wood, but smaller in ambition. What matters here is the orientation it gives you. Lima does not have an obvious center for first-time visitors, and Plaza Mayor provides one. Walk there via Jirón de la Unión, the pedestrian street connecting the San Martín area, but go before 10am. By midday the foot traffic thickens and the pickpocket risk rises.

Your third stop should be Huaca Pucllana, a pre-Inca adobe pyramid from roughly 400 AD that sits in the middle of Miraflores between apartment towers. The nighttime illuminated tour, Wednesday through Monday at about 15 soles, is the better version. The adobe bricks glow warm orange under floodlights and the air drops to around 17°C, comfortable in a light jacket. Mind you, the site is smaller than photos suggest. Budget 45 minutes. The attached restaurant, also called Huaca Pucllana, runs 80-120 soles per main course. Expensive by Lima standards, but ceviche eaten 3 metres from a 1,600-year-old pyramid at night is a meal with staying power. Skip the National Stadium and the Estadio Monumental unless you have match-day tickets. Lima's stadiums live on crowd energy. Without 40,000 fans, they are concrete shells.

Lima scores 4.2 out of 10 on TTDI's solo-traveler safety index (see the TTDI Solo-Safety Index), which means standard urban precautions plus a few local ones. Don't walk between Miraflores and Barranco after dark. Use registered taxis or InDrive, the ride-hailing app that undercuts Uber in most Lima districts. The garúa, Lima's persistent coastal fog, makes August days overcast and cool. Currently around 21°C with 78% humidity. Pack a light waterproof layer rather than sunscreen. You won't need an umbrella. The moisture is more of a fine mist on your skin than actual rain. The three sites form a triangle that a taxi can connect in about 40 minutes of total drive time, and none requires advance booking.
