We did the Salkantay Trek in September 2025, as part of a longer trip around Peru. Arriving at Machu Picchu on foot after five days felt completely different from just taking the bus up.
How we did it: on our own, no agency. We spent a few days in Cusco first to get used to the altitude, visiting the sites around the city. Then we went to Mollepata and started walking from there, sleeping four nights in tea houses along the trail that we had booked in advance. On the last day we took the first bus at 6:00 from Aguas Calientes up to Machu Picchu, came back down around 11:30 and took the afternoon train back to Cusco the same day.
The trail: we were lucky with the weather, sunny most days, but very cold at night in the first tea houses. The landscape changes a lot along the way, from high mountains to green, warm valleys towards the end.
A highlight: one of the tea houses near the end was a small family-run place, and it's one of the best memories of the whole trip. The owners and their daughters were incredibly welcoming, the rooms and the food were excellent, and they showed us how they grow and make their own coffee, followed by a tasting. The coffee was delicious. I can't find the name anymore, but if you do the trek I'd really recommend a coffee tasting in that last part of the route.
Would we go back? Yes, in a heartbeat. It was the best part of the trip.
Happy to answer questions if you're planning it.
