At the heart of Unhais da Serra, the Feira do Queijo (Cheese Fair) offers more than just a taste test; it’s a celebration carved from mountain tradition and the raw character of the Serra da Estrela. This annual fair invites visitors to engage not only with local cheeses but also with the demanding terrain and striking scenery that shape their origins.

The hike to Feira do Queijo begins just outside Unhais da Serra, guiding adventurers along roughly 8 kilometers of varied terrain with an elevation gain around 450 meters. Expect a path that challenges with rocky patches and occasional steep ascents, but rewards with wooded groves where pine and oak seem to deliberate over your progress, and cliffs that dare you to look beyond the next ridge.

This is not a trail where nature is a silent backdrop; rivers push insistently forward in the valleys below, and the mountain wind carries whispers of local lore. The fair itself is unmissable, with stands offering aged Serra da Estrela cheeses, complemented by regional breads and honey—perfect fuel for hikers and curious visitors alike.

To prepare, bring sturdy hiking shoes with solid grip to navigate stones slick from mountain moisture. Hydration is critical; water sources are sparse on the trail, so carry at least 1.5 liters per person. Early arrival is advised—morning hours reveal cooler air and softer light, enhancing both the trek and photographic opportunities.

The fair runs over a weekend, usually in July, promoting an interplay of joyous human activity against the steady, unmoving landscape. Vendors range from local producers to artisans offering crafts tied closely to the land. The event is a prime spot to learn about cheese-making techniques passed down through generations and absorb the rugged charm of Serra da Estrela’s cultural identity.

In practical terms, the trail’s moderately challenging nature means it suits fit casual hikers and seasoned trekkers looking for a blend of cultural immersion and outdoor exertion. With adequate water, weather-appropriate clothes, and a readiness to meet nature’s fierce independence, visitors find the Feira do Queijo to be both a rewarding physical journey and a profound sensory experience.

Whether tasting the dense, creamy cheeses that cling to mountain herbs or stepping along the forested inclines back toward Unhais da Serra, the event and its environment show a mutual respect that must be earned by every traveler. This fair and its surrounding trails offer a slice of authentic Portuguese mountain life, inviting each adventurer to step in and engage with a place fiercely itself.
