The Best Time for the Inca Trail

February is the month to avoid for the 4-day Inca Trail. The trail routes were closed through 28 February 2026 and reopened on 1 March, SERNANP announced, and trek companies plan around it: Alpaca Expeditions’ Viator calendar runs to 31 January 2027 and starts again on 1 March 2027. Outside February, the trail can still close: after unusual rainfall in August 2026, entry was stopped until 5 September. No notice for February 2027 had been published on 12 November 2026. So pick a date outside February, book early for the months Machu Picchu is busiest, and pack for rain whatever the month.

Is the Inca Trail closed in February?

It was in 2026. SERNANP, the agency that runs Peru’s protected areas, announced that routes 1, 2, 3, 5 and 6 of the Inca trail network to Machu Picchu were not open for tourist visits through 28 February, to allow the natural recovery of the ecosystems and to maintain the trail’s infrastructure and visitors’ safety; visits resumed on 1 March 2026 (Andina, 27 January 2026). Route 1 is the classic 4-day trek from Km 82 and route 5 the 2-day short Inca Trail from Km 104. Andina also reported in December 2025 that the 2026 Inca Trail schedule excluded February, when the walks are suspended for maintenance and conservation.

For February 2027, no notice had been published as of 12 November 2026. The Machu Picchu citadel itself is a separate site with its own rules; the February notice was about the trail routes.

The rain closure of August and September 2026

Closures are not only a February thing. In early September 2026 the culture directorate in Cusco and SERNANP announced that tourist entry to the Inca Trail would resume on Saturday 5 September, after unusual rainfall more than two weeks earlier had caused landslides, overflowing streams and flooding, damaged footbridges and eroded the path (Andina, 4 September 2026). Hikers on TreXperience’s trek have met this: in its recent reviews, one on 27 March 2025 says the trek had to be re-planned because rain made the trail impassable, with an alternative offered, and one on 23 August 2026 that heavy rain stopped the group continuing on the trail. The latest notice is the one that counts.

Machu Picchu’s busy season in 2027

The culture ministry sets how many people may enter Machu Picchu each day. For 2027 its resolution of 31 October 2026 (RM 000408-2026-MC) sets a high season of 147 days with a capacity of 5,600 visitors a day: 1 to 3 January, 25 to 28 March, 19 June to 2 November and 29 to 31 December 2027. On the other dates of 2027 the capacity is 4,500 a day. Those are the citadel’s figures, not the trail’s: the resolution says nothing about the number of Inca Trail places.

What it tells a trekker: June to early November is when Machu Picchu expects the most visitors, so those are the dates to book first.

Inca Trail weather: what the treks tell you to pack

This page prints no climate averages; the treks’ packing lists are enough to pack by. For TreXperience’s 4-day trek you bring rain gear, weather-appropriate clothing and a sun hat, and every hiker gets a rain poncho. Sunglasses, sunscreen and insect repellent are on the same list: pack for rain and for sun, in any month.

Which months, then?

• 19 June to 2 November 2027: the ministry’s high season for Machu Picchu. Book these dates first.
• The rest of the year except February: Machu Picchu’s regular season, apart from 1 to 3 January, 25 to 28 March and 29 to 31 December 2027. Rain is possible in any month, as August 2026 showed.
• February: the trail was closed through 28 February 2026; for February 2027, look for SERNANP’s notice before you plan (none published on 12 November 2026).
