When most travelers think of Costa Rica, they imagine the busy holiday months of December or the lush peak season of summer in Central America when North America and Europe are in winter. But those in the know whisper about September and October—the “secret season” in Arenal. At Montaña de Fuego Resort & Spa, the secret season offers a rare blend of peace, clear volcano views, and authentic local culture, making it one of the most rewarding times of year to visit. September and October are the months of the year when La Fortuna’s weather is most stable. The volcano can be seen for longer periods, not just in the mornings, and almost always there are incredible sunsets that paint the Arenal Volcano and the sky in deep reds during the afternoons. It’s the perfect season for those seeking to recharge with the volcanic energy of Arenal.
Clearer Volcano Views
Arenal’s “shoulder season” is when rains taper and skies often open in brilliant clarity. This means some of the best volcano visibility of the year, perfect for photographers, couples looking for dramatic sunset backdrops, or families eager to finally see the full cone revealed. Imagine sipping coffee on your bungalow terrace as the morning mist lifts, unveiling Arenal in all its glory.
Travelers who come in September enjoy a calmer pace. With fewer crowds, popular attractions like waterfall hikes and hanging bridges feel more personal. At Montaña de Fuego, the thermal mineral pools, spa treatments, and mud station take on an even more serene atmosphere, ideal for couples seeking a quiet escape or parents wanting to recharge while older kids explore the gardens.
September also brings Costa Rica’s Independence Day on September 15, a vibrant holiday filled with parades, music, and cultural pride. Staying in Arenal during this time offers a chance to experience traditions alongside locals. For families, it’s a wonderful opportunity to show children authentic Costa Rican culture. For couples, it’s a chance to step beyond the resort and immerse yourselves in community celebrations.
Another secret advantage of visiting in September is value. With fewer international visitors, rates are often more favorable, allowing you to enjoy luxury experiences—like a couple’s spa package or guided wildlife tour—at a better price. Families find that their budgets stretch further, making longer stays possible.
September and October are the perfect months to experience Arenal at a slower, more peaceful pace. Couples can slip into the warm embrace of our mineral thermal pools, surrounded by lush rainforest, where the quiet and the fewer crowds set the stage for romance and connection. Families with older kids will love the freedom of roaming scenic trails, spotting toucans and other wildlife, or joining exciting adventure tours. Meanwhile, parents can unwind at the spa knowing everyone has space to enjoy themselves. With calmer days and more room to breathe, these months invite you to truly relax, recharge, and make memories together.
The secret is out: September and October in Arenal offers tranquility, clear volcano views, cultural celebrations, and incredible value. Whether you’re planning a romantic all inclusive escape or a family trip, Montaña de Fuego is ready to make your experience unforgettable.
