Why this route

Mendoza and Colchagua sit 400 km apart across the Andes, and together they show the two faces of South American wine: high-altitude Malbec at 900 to 1,100 m on the Argentine side and coastal Carmenere 120 km from the Pacific on the Chilean side. In 2026 a 6-day combined route lists at 1,800 to 2,400 USD per person with boutique hotels, private tastings, and the Andes crossing, or 1,200 to 1,500 USD per side as a 3-day trip. Tastings run 15 to 40 USD per bodega, premium flights to 70 USD, and the bike loop through Lujan de Cuyo covers 15 km across four wineries in a day. Harvest runs February through April, when working wineries smell of fermentation and tours run longest.

The Andes crossing between the two valleys takes a full day: 400 km in 7 to 9 hours including the border, with the Cristo Redentor pass at 3,200 m. We fly into Mendoza and out of Santiago to avoid backtracking, an open-jaw pattern that saves a day. Both valleys sit at comfortable altitudes, 900 m in Mendoza and 300 m in Colchagua, so no acclimatization is needed. This route suits travelers who want slow afternoons: tastings end by 18:00, dinners start at 21:00 Argentine style, and midday is built for long lunches at the bodegas.

The log: two valleys, one crossing

Six dated entries from Mendoza's Malbec rows to Colchagua's Carmenere. Tasting counts kept moderate daily.

Day 1 - Mendoza arrival, 750 m

We meet your flight at Mendoza airport, 20 minutes to the city center, and check in at a boutique hotel, 90 to 130 USD. The afternoon is the city park and the wine museum, entry 8 USD, 90 minutes on irrigation history. Evening briefing at 18:00 covers the week's tasting order and the crossing-day paperwork. Dinner is asado with Malbec, about 25 USD, starting at the local hour of 21:00.

Day 2 - Lujan de Cuyo bike loop, 15 km

Bikes are fitted at 09:00 and the 15 km loop covers four Lujan de Cuyo bodegas by 16:00, tastings 15 to 25 USD each with the bike rental at 20 USD. Midday is the long bodega lunch, 35 USD with pairings, seated among the vines. Afternoon pedals back through olive groves, and the evening is free in Chacras de Coria, 15 minutes from town. Total tasting count: four bodegas, twelve pours, zero rush.

Day 3 - Uco Valley altitude wines

The 08:00 drive covers 80 km south to the Uco Valley at 1,100 m, where three premium tastings at 30 to 70 USD run across the day. Midday is the vista lunch at 1,200 m with the Andes wall behind the vines, 40 USD. Afternoon covers the concrete-egg cellar tour, 45 minutes, and the return by 18:00. Evening is rest; altitude tastings at 1,100 m dehydrate faster than the numbers suggest.

Day 4 - Andes crossing to Chile, 3,200 m

Departure at 07:00 for the 400 km crossing via the Libertadores pass at 3,200 m, with border formalities taking 1 to 3 hours depending on the queue. Midday is a roadside lunch at 12 USD on the Chilean slope, then the descent through 29 switchbacks to the central valley. Arrival in Santa Cruz, Colchagua, by 17:00 after 9 hours total. Evening is an early dinner, 18 USD, and the wine-week second half begins.

Day 5 - Colchagua valley loop

Morning is the Santa Cruz museum, entry 10 USD, 2 hours on pre-Columbian and railway history, then the first Carmenere tasting at 11:00. Midday is the Viu Manent-style carriage tour option, 25 USD, rolling through 150-year-old vines. Afternoon covers two boutique bodegas at 20 to 30 USD each, with the Syrah vertical the standout pour. Evening is the Colchagua wine and food dinner, 30 USD, in Santa Cruz town.

Day 6 - Return to Santiago

The 180 km drive north reaches Santiago in three hours by midday, with an optional Cachapoal stop for a final tasting at 15 USD. Afternoon is airport transfers or a Santiago hotel night, 80 to 110 USD, and the week's bottle count ships home by courier at 60 to 90 USD per case. Total 2026 route spend lands near 1,800 to 2,400 USD per person combined. We close with a feedback call within a week.

If you go

Wine weeks fail on transport, not on wine. The 2026 notes below keep the order sound.

• Fly into Mendoza and out of Santiago; the open-jaw pattern saves a full backtrack day.
• Budget 1,800 to 2,400 USD combined or 1,200 to 1,500 USD per side with boutique hotels and tastings.
• Cap tastings at four bodegas a day; pour twelve is where notes stop being notes.
• Travel harvest season February to April for working cellars, or October to November for mild weather.
• Carry passport copies for the crossing; border queues run 1 to 3 hours and officers keep the originals moving.
• Ship wine by courier at 60 to 90 USD per case; airline baggage rules cap bottles at five liters per person.
• Confirm Sunday hours before routing; smaller bodegas close and the bike shops rent half day.

We start with a walk-through call, draft the bodega order by your varietals, lock the crossing transfer, and brief you in Mendoza. Our line tracks every tasting and transfer daily.
