Reinosa’s Festival of San Mateo lights up the early autumn air every September, blending tradition and vibrant celebration against Cantabria’s rugged backdrop. This festival isn’t just a local feast; it’s a calling for adventurers and culture seekers alike to engage with a community fiercely proud of its heritage. The streets fill with the rhythm of traditional music, the clatter of folk dances, and the aromas of hearty Cantabrian fare, all set beneath the sharp blue skies of northern Spain.

Held on September 21st, San Mateo honors both the harvest season and Reinosa’s patron saint with events that thread through the town’s historic heart. The festival’s pulse is in its parades—characterized by colorful costumes, horse processions, and the unmistakable clang of bells that dare you to match their energy. This isn’t a passive observance; it invites participation, a chance to walk alongside those who guard the past with open arms and fierce pride.

Beyond the vibrancy of the day’s events, visitors can explore the rugged environs surrounding Reinosa. The nearby Campoo region offers trails that weave through thick oak and beech forests, with streams daring hikers to cross their cool, rushing paths. Expect moderate hikes stretching 8 to 12 kilometers, with elevation gains around 300 to 600 meters, taking you from Reinosa’s quaint streets into wild, open spaces where Cantabria flexes its muscles. Footwear designed for mixed terrain is a must—muddy patches after rain, rocky segments, and sudden inclines require steady footing.

Planning to attend? Start early to catch the quieter moments before crowds gather. Hydration is key; Spanish autumns can surprise with unexpectedly warm days under clear skies. Local eateries reserve their best for this period—don’t miss dishes like cocido montañés, a nourishing bean and meat stew that fuels both body and spirit. For those camping nearby, prepare for crisp nights where the air tightens as the sun dips, and star fields stretch wide.

The Festival of San Mateo in Reinosa marries culture with nature’s challenge. It’s not about conquering but becoming part of a living tradition, understanding a place that thrives on being fiercely itself. Whether dancing along cobbled streets or hiking to panoramic ridges, this experience encourages respect, energy, and an appetite for discovery.
