Puno
"Puno hits you at 3,800 metres before you've even found your hotel — the altitude is the first thing it teaches you about itself."
The bus from Cusco drops you at Puno’s terminal terrestres in the early morning and the first thing you feel is the altitude. Not pain exactly — more like someone has quietly turned down the air pressure by ten percent. The city spreads up a hillside above the lake, densely built in the way of highland cities that have grown faster than their plans, with a centre that opens onto a wide Plaza de Armas and a cathedral whose Baroque facade is so elaborately carved it looks like lace made from stone. I sat on a bench in the plaza and drank the first of many cups of mate de coca, watching a retired couple photograph a fountain and a group of schoolgirls in identical blue jumpers argue about something urgent.
Puno gets written off by travellers using it purely as a transit hub to the islands, which is a mistake. The Mercado Central is one of the most comprehensive market environments I’ve encountered on the altiplano — not cleaned up for tourists, not repackaged. Women sell chicharrón wrapped in newspaper, chefs de cuisine pick over piles of chuño and purple potatoes, and a section of the market devoted to herbal remedies offers bottles of things whose labels range from “for circulation” to descriptions I couldn’t quite translate. The smells are layered and honest: dried herbs, frying oil, something fermented in the direction of chicha.

The cathedral on the plaza dates to 1757, built in the regional Mestizo Baroque style that blends Spanish architectural vocabulary with Andean iconography — look for the pumas and condors hidden among the stone carvings, the local flora worked into the pilasters. Inside it is relatively austere, almost dim, with a silver altar that gleams in the candlelight. The contrast with the exuberant exterior is the kind of thing that stops you mid-step.
Puno’s real character emerges during its festivals. The Fiesta de la Candelaria in early February is one of the great folk celebrations in South America — the plaza and surrounding streets fill with thousands of dancers from across the altiplano, each group in extraordinary hand-sewn costumes that take months to make. Diabladas, morenos, tuntunes: the dance forms are distinct and ancient and extremely loud, with brass bands competing at full volume for blocks in every direction. I was there on a random May Tuesday and none of this was happening, but the ghost of it was still visible in the way people talked about the plaza.

The waterfront port district is a twenty-minute walk from the plaza, and the late afternoon light on the harbour — the boats loading, the pelicans on the pilings, the lake turning from blue to gold to something almost violet — is when Puno stops being a city you pass through and starts being a place. I ate caldo de cabeza at a stall by the water, which is cow’s head broth and much better than the description suggests, and watched a freighter head toward the Bolivian shore until I lost it against the far mountains.
When to go: May through October for reliable dry weather. February for the Candelaria, which requires booking accommodation months in advance — the city triples in population for the main weekend. Give yourself at least one full day in Puno before heading to the islands; the altitude adjustment is real and a rushed head is not the best way to start a boat trip.
