City Lanes or a River Valley
Cusco feels like reading two histories at once. Lower walls of fitted gray andesite carry whitewashed colonial plaster, Qorikancha's convent rises over the curved stones of the Temple of the Sun and the Plaza de Armas fills with families on Sunday afternoons. UNESCO lists the whole historic center. It is a place for wandering without a plan, ducking into a gallery or a courtyard café on a whim.
The Sacred Valley is the opposite mood. Corn fields, eucalyptus groves and terraces that still hold crops run along the Urubamba for some 37 miles, with snowy peaks on both sides. Towns are small and the distances between them are real, so you drive from sight to sight instead of walking.
Couples who light up in old cities usually fall for Cusco. Couples who want long lunches outdoors and quiet evenings by a fire tend to prefer the valley.
Altitude and How You Will Sleep
This is the deciding factor for many couples. Cusco sits at about 11,150 feet. Most people feel it on arrival: shortness of breath on the steep San Blas lanes, a headache, a restless first night. It passes for most visitors after a day or two, but it can take the edge off the start of a honeymoon.
Urubamba, in the middle of the valley, is roughly 1,700 feet lower. Afternoons are warm enough for lunch in the sun and most couples sleep better from the first night. That is why many itineraries skip Cusco on arrival entirely and drive straight down from the airport.
If Cusco is where you want to be, a few hotels help. Belmond Hotel Monasterio offers oxygen-enriched rooms and Palacio Nazarenas pumps oxygen into its suites. Either way, go light on alcohol for the first night or two and drink the coca tea every hotel offers. If altitude has hit you hard before, talk to your doctor before the trip.
When Each One Shines
Both follow the same Andean calendar. May through September is the dry season, with bright days, intense midday sun and cold nights that can drop to freezing in June and July. April and October are the shoulder months, greener and calmer, with softer hotel rates.
The difference is in what each place does with its season. Cusco has the big festivals. Inti Raymi on June 24 reenacts the Inca sun ceremony at Sacsayhuamán. Corpus Christi fills the main square with processions of saints. Both are thrilling to see, but hotels fill early. At Christmas the Santurantikuy handicraft market takes over the plaza.
The valley's rhythm is gentler. Pisac's market runs daily and is busiest on Sundays. In the wet months, roughly November to March, the valley is at its greenest, though trails get muddy and the odd landslide can disrupt roads or the railway. Cusco handles rain better, since museums and restaurants are a short walk apart.
Convent Suites or Hacienda Casitas
Cusco's best hotels live inside history. Palacio Nazarenas, A Belmond Hotel, is a former convent turned all-suite hotel with a heated pool. Belmond Hotel Monasterio wraps around a sixteenth-century cloister next door. Inkaterra La Casona has only a handful of suites in a mansion on Plaza Nazarenas. San Blas adds smaller guesthouses with a bohemian street scene, though its stairs are steep.
The valley has room for gardens and views a city lot cannot match. Inkaterra Hacienda Urubamba sits on a working farm with mountain views. Sol y Luna, a Relais & Châteaux member, is known for colorful bungalows and Peruvian Paso horse shows. Explora Valle Sagrado runs on an all-inclusive model built around daily guided hikes. Belmond Rio Sacred Valley puts adobe casitas on the riverbank and Tambo del Inka has a spa plus its own train platform.
For one unusual night, Skylodge Adventure Suites hangs glass pods on a cliff face above the valley, reached by via ferrata.
Eating and Drinking
Cusco is the best place to eat in the Andes. Chicha, from chef Gastón Acurio, serves regional dishes near the main plaza. Cicciolina has a tapas bar and candlelit dining room. Pachapapa in San Blas cooks in a wood-fired clay oven in a courtyard, which is the dinner couples remember. Mornings at San Pedro market, with juice pressed to order, make a fine start to a cooking class. Evenings end in pisco bars over sours and chilcanos.
The valley has fewer restaurants but one headline table. Mil, from Virgilio Martínez of Lima's Central, sits on the rim above Moray and serves a tasting menu of high-altitude ingredients with views over the terraces. Book it well ahead. Otherwise you eat at your hotel or join a pachamanca, meat and potatoes slow-cooked underground on hot stones.
If food is a big part of how you travel, give Cusco at least two nights. In the valley, plan one long lunch at Mil and enjoy hotel dining the rest of the time.
Ruins and Days Out
Cusco's sights are mostly walkable. Start at Qorikancha, find the twelve-angled stone on Hatun Rumiyoc, then take a taxi up to Sacsayhuamán in late afternoon and walk down to San Blas as the lights come on. The Museo de Arte Precolombino holds ceramics and gold in a colonial mansion. Fit hikers use the city as a base for Rainbow Mountain or Humantay Lake, both well above 13,000 feet.
The valley's ruins are bigger and quieter. Pisac's terraces climb a mountainside above the market town. Ollantaytambo's temple fortress overlooks streets still laid out on the Inca plan. It empties in late afternoon when the day tours leave. On the plateau, many couples cycle with a guide from the circular terraces of Moray to the Maras salt pans. In Chinchero, a weaving cooperative shows how alpaca wool is dyed and woven.
The Boleto Turístico covers sites in both places, so one ticket serves the whole stay.
Getting In and Moving Around
Everyone lands at Cusco (CUZ), usually after connecting in Lima, since there are no nonstop flights from the US. The airport is 15 to 20 minutes from the historic center, which makes Cusco the simpler first or last stop on paper.
The valley is about 1 to 1.5 hours by road to Urubamba, via Chinchero or Pisac. Most good hotels arrange private transfers. Once there, you need a driver or guide to get around, because sites are spread out and taxis are scarce at the ruins late in the day.
For Machu Picchu the valley wins clearly. Trains leave from Ollantaytambo and reach Aguas Calientes in about 1.5 hours. From Cusco you start at Poroy station, about 20 minutes outside town. That ride takes longer. Cusco is the departure point for the PeruRail Titicaca train to Puno and the Belmond Andean Explorer. Check with your hotel about strikes or road blockades, which occasionally affect travel between the two.
How to Split Your Nights
The order that works for nearly everyone is valley first, Machu Picchu in the middle, Cusco last. You land in Cusco, drive straight down to the valley and settle in at lower altitude. After three or four nights you take the train from Ollantaytambo to Aguas Calientes, spend a night below the citadel and ride back to Cusco with your body adjusted to the thin air.
With five nights in the region, try two in the valley, one at Machu Picchu and two in Cusco. With seven, go four, one and two. With ten or more, add Lake Titicaca after Cusco by train.
If you must pick only one base, the valley is the better honeymoon choice for most couples, since it is easier on the body and closer to Machu Picchu. Pick Cusco alone only if city life is the point and you have handled altitude well before.
