With fewer crowds than peak season, mild temperatures, and greener landscapes, October is a great time to hike the legendary trail.
In this comprehensive guide, we’ll cover everything you need to know about doing the Inca Trail in October: weather conditions, permits, difficulty, packing tips, pros and cons, and practical recommendations to help you prepare for the adventure of a lifetime.
Weather on the Inca Trail in October

Temperature: During the day, temperatures range between 15°C and 20°C (59°F–68°F). Nights can get cold, dropping to 5°C (41°F) or lower at higher altitudes.
Rain: October brings occasional showers, but rainfall is not as intense as in December–March. Expect a mix of sunny days, cloudy skies, and light rain.

Visibility: Clouds can sometimes cover the mountains, but generally you’ll still enjoy clear views of the Sacred Valley and Machu Picchu.
✅ Verdict: Weather in October is manageable, with more greenery than the peak dry season but without the heavy rains of December–February.
Is October a Good Time to Hike the Inca Trail?
Yes, October is a great month for the Inca Trail. Here’s why:
Advantages
Fewer Crowds: October is outside the busiest season (June–August), so the trail and Machu Picchu are less crowded.
Easier Permits: In peak season, permits sell out months in advance. In October, you’ll still need to book early, but there’s more availability.
Greener Landscapes: The first rains bring life back to the valleys, making the scenery lush and colorful.
Good Weather Balance: Not as dry as September, not as wet as December – October is a balance between both.
Disadvantages
Unpredictable Weather: Showers can occur at any time.
Humidity: Trails may be slippery, so good hiking boots are essential.
Shorter Days: Less daylight compared to June–August.
Inca Trail Permits in October
All hikers must have a permit to trek the Classic 4-Day Inca Trail. These permits are limited to 500 per day (including guides and porters) and often sell out quickly.
Availability in October: Easier to secure than in peak months, but still recommended to book 3–4 months in advance.
Where to Book: Only licensed tour operators can reserve permits. Independent trekking is not allowed.
If permits are sold out, alternatives include the Short Inca Trail (2 days) or other treks such as Salkantay or Lares.
