Inca Trail in May

May is, for many travelers and local guides, one of the most recommended months to hike the Inca Trail. It marks the start of the dry season in the Peruvian Andes: the heavy rains of the previous months begin to taper off, skies clear up, and the landscape still holds the lush greenery left over from the wet season. In many ways, it’s the perfect combination of good weather and vibrant scenery.

That combination comes with a trade-off, though: May is also one of the months with the highest demand for Inca Trail permits. In this article, we cover what to expect from the weather, how permit availability works, what to pack, and how to plan your booking early enough to avoid missing out.

If you’re not yet familiar with the general route details, we recommend first checking out our complete Inca Trail guide, which covers the itinerary, difficulty level, and everything you need to know before booking.

Why May Is One of the Best Months for the Inca Trail

Trekking season in the Cusco region is broadly split into two periods: the wet season (roughly November to March) and the dry season (April to October). May falls right at the start of the second one, making it a transitional month with several advantages:

• Less rain than during the wet months, but landscapes still green and lush, unlike June, July, or August when things start to dry out.
• Clearer skies, ideal for photography and for enjoying panoramic views at the trail’s highest points, such as Warmiwañusca Pass (Dead Woman’s Pass).
• Pleasant daytime temperatures, though nights at altitude can still be quite cold, especially at campsites above 3,500 meters.

Many experienced trekkers consider May, along with September, to be the sweet spot between great weather and lower crowds compared to the absolute peak of dry season (June, July, and August).

Weather in May: What to Expect

During May, the probability of rain drops noticeably compared to previous months, though it doesn’t disappear entirely, especially early in the month. Typical weather patterns for May along the Inca Trail include:

• Sunny, mild days, with temperatures typically ranging between 15°C and 20°C (59°F–68°F) during the day at the lower sections of the route.
• Cold nights, with temperatures that can drop below 0°C (32°F) at higher-altitude campsites, particularly before crossing the highest pass.
• Decreasing humidity, which reduces the likelihood of dense morning fog, improving visibility along scenic stretches.
• Occasional light rain, especially during the first few days of the month, since the seasonal transition isn’t instant.

Overall, May offers far more predictable and pleasant conditions than the rainy season, without yet reaching the dryness and dust typical of the peak Andean winter months.

Permits in May: High Demand

Here’s the most important thing anyone planning a trip during this time needs to know: May is one of the highest-demand months for permits on the classic Inca Trail, alongside June, July, August, and September.

A few key facts about permits:

• Daily capacity is around 500 people, including guides, porters, and cooks, which in practice leaves between 200 and 250 spots available for tourists per day.
• During May, especially in the second half of the month, permits typically sell out 4 to 6 months in advance, and in some years even earlier.
• Permits can’t be purchased directly by individual travelers — they must be booked through a licensed operator, who processes the purchase on the traveler’s behalf using their passport number.
• Once a specific day’s quota is sold out, there’s no way to obtain an additional permit for that date, regardless of price.

If your goal is to hike the classic Inca Trail in May, the recommendation is clear: book as far in advance as possible, ideally 5 to 8 months before your travel date. To see how May compares to the rest of the annual calendar, check out our article on the best time to hike the Inca Trail.

What to Pack for the May Trek

Given the contrast between daytime and nighttime temperatures, and the possibility of light rain early in the month, the right gear makes a big difference to your experience:

• Layering system: a thermal base layer, an insulating mid layer (fleece or lightweight down), and a waterproof/windproof outer shell.
• A sleeping bag rated for low temperatures, ideally rated to at least -5°C to -10°C (23°F to 14°F), since nights at high-altitude campsites can be very cold.
• Lightweight waterproof clothing, in case of light rain during the first days of the month, though rainfall will be much lighter than during the wet season.
• High-SPF sunscreen and sunglasses, since May’s clear skies mean greater UV exposure at altitude.
• Waterproof, well broken-in trekking boots, to avoid blisters over the 4 days of hiking.
• A reusable water bottle or hydration system, along with purification tablets or a filter, given the physical exertion and altitude.

Booking Tips

To secure your spot on the Inca Trail during May, keep these practical recommendations in mind:

1. Book 5 to 8 months ahead. The sooner you lock in your dates, the higher your chances of getting the exact day you want, especially if traveling as a group.
2. Build in 2–3 days of flexibility. If your ideal date is already sold out, having nearby alternatives significantly increases your options.
3. Confirm the operator is licensed. Only operators authorized by the Ministry of Culture can process Inca Trail permits — verify this before booking and paying.
4. Have your passport ready when booking. The permit is issued in the exact name of the person doing the trek, so you’ll need a valid passport number at the time of booking, not just upon arrival in Cusco.
5. Consider booking your flights and Cusco accommodation with the same lead time, since May is also high season for domestic flights and hotels in the region.

Alternatives If You Can’t Get a Permit

If you find that permits for your May dates are already sold out, that doesn’t mean giving up on a trekking experience to Machu Picchu. There are excellent alternatives with no quota restrictions:

The Salkantay Trek (open year-round) is the most popular alternative, with spectacular high-mountain scenery and no need to book limited permits. You can review all the details in our complete Salkantay guide.

You might also consider the combination of Lares and short Inca Trail, which offers a deep cultural experience through traditional Andean communities before connecting to a short stretch of the classic Inca Trail on the way to Machu Picchu.

Both alternatives can be booked with far more flexibility, even just a few weeks out, and offer equally memorable experiences.

Final Recommendation

May is, without a doubt, one of the most attractive months to hike the Inca Trail: it combines favorable weather, green landscapes, and clear skies in a balance that’s hard to find at other times of year. The key is planning ahead — if you lock in your dates and book early enough, ideally 5 to 8 months in advance, you’ll have a strong chance of securing your permit for the exact dates you want.

If you’d rather avoid the uncertainty of limited permits, the Salkantay Trek or Lares combined with the short Inca Trail are excellent alternatives you can book with much more flexibility.
