Inca Trail in May

The Inca Trail in May is one of the most rewarding times of the year to hike the legendary path leading to Machu Picchu. May marks the beginning of the dry season in the Peruvian Andes—arguably the best moment for trekking—offering clear skies, vibrant green landscapes from recent rains, stable weather, and ideal temperatures for long days of hiking. Because of these exceptional conditions, May has become one of the most popular months for the Classic 4-Day and Short 2-Day Inca Trail routes.

Why Hike the Inca Trail in May?

Choosing to hike the Inca Trail in May comes with a long list of advantages:

1. Start of the Dry Season

May is the first “true” month of Peru’s dry season. Rainfall decreases significantly, but the valleys and mountains are still lush and green from March and April’s moisture—creating the perfect balance between good weather and beautiful scenery.

2. Excellent Visibility

If you want clear, wide-open views of snow-capped peaks such as Veronica, Salkantay, and the surrounding cloud forests, May delivers. Sunrises and sunsets are spectacular, especially from viewpoints like Dead Woman’s Pass and Intipunku (Sun Gate).

3. Comfortable Temperatures

Daytime temperatures range between 18°C and 22°C (64–72°F), perfect for hiking. Nights can be cold but not as freezing as June or July.

4. Fresh Wildlife Activity

Because the vegetation is still abundant after the rainy season, May is one of the best months to spot orchids, hummingbirds, butterflies, and small mammals along the route.

5. Highlight Month for Machu Picchu

May offers some of the clearest views of Machu Picchu all year. Photographers often choose this month because the atmosphere is crisp, the skies are blue, and the citadel is surrounded by vivid green mountains.

Overview of May Weather

May has ideal trekking weather:

Crowds on the Inca Trail in May

Because May marks the start of peak trekking season, permits for this month sell out extremely fast, often 5–6 months in advance. The Inca Trail only allows 500 permits per day (including guides, cooks, and porters), so availability is limited.

Expectations Regarding Crowds

• Campsites such as Wayllabamba and Pacaymayo may feel busy.
• Viewpoints like Dead Woman’s Pass can have medium to heavy traffic at peak hours.
• Arriving early to viewpoints is recommended for a calmer experience.
• The Sun Gate (Intipunku) sunrise can be crowded, but the lighting in May makes it totally worth it.

Inca Trail Permits for May

To hike the Inca Trail in May, travelers must secure permits well in advance—typically between October and January of the previous year.

Permit Tips

• Book at least 6 to 9 months ahead.
• Only authorized tour operators can purchase permits—independent trekking is prohibited.
• Your passport details must match the permit exactly.

May is one of the top three busiest months (along with June and July), so early planning is essential.
