Why October is ideal for hiking in Portugal
October is one of the most rewarding months to explore Portugal on foot. With its blend of pleasant weather, peaceful trails and vibrant seasonal scenery, it offers the ideal conditions for a walking adventure.
Whether you’re trekking along coastal cliffs or through vineyard-covered valleys, hiking in October allows you to experience the country’s landscapes at their most serene and colourful. Here’s why this time of year stands out for hikers of all levels.
1. Mild and comfortable weather
By October, the sweltering summer heat has cooled, making hiking far more comfortable. Daytime temperatures typically range from:
- 15–25°C (59–77°F) in the north and inland valleys;
- 18–27°C (64–81°F) along the southern coast (Algarve and Costa Vicentina).
You can hike under clear skies without the intense sun exposure of summer or the cold of winter. Early mornings and evenings may be crisp, but nothing that a light jacket can’t handle.
2. Fewer tourists, quieter trails
October marks the end of the high tourism season in Portugal. That means less crowded trails, more authentic local encounters, and better availability at charming rural accommodations. You'll have more space to enjoy the natural beauty and cultural richness of each region.
3. Autumn landscapes and harvest season
Portugal in October is painted in hues of gold, rust and amber, especially in regions like the Douro Valley and Peneda-Gerês National Park.
Vineyards glow with the changing leaves, and the olive and grape harvests are in full swing, offering a unique opportunity to pair hiking with local food and wine experiences.
