Where to Go in Costa Rica in September

Planning a trip to Costa Rica in September? This time of year is often called the “green season,” with lush landscapes, fewer crowds, and authentic local experiences.

While some travelers shy away because of occasional rain, September is one of the best months to explore Costa Rica’s national parks, beaches, and cultural hubs without the usual tourist rush. From volcanic adventures to Caribbean vibes, let’s dive into the top destinations you should visit in September.

Arenal Volcano and La Fortuna

No trip to Costa Rica is complete without a stop at Arenal Volcano and the nearby town of La Fortuna. September brings misty mornings and vibrant greenery, making hiking trails around the volcano especially breathtaking.

The cooler weather is perfect for exploring waterfalls and the famous Tabacon hot springs, where you can soak in naturally heated mineral waters surrounded by rainforest. Travelers also enjoy canyoning, ziplining, and visiting the Celeste River in the nearby Tenorio Volcano National Park, famous for its magical blue hue.

Monteverde Cloud Forest Biological Preserve

September is a wonderful month to explore the Monteverde Cloud Forest Biological Preserve, home to an astonishing variety of flora and fauna.

Birdwatchers can spot resplendent quetzals, hummingbirds, and rare orchids while walking along hanging bridges through the misty canopy. The rains keep the forest alive with color and sound, offering an unforgettable experience for eco-travelers.

Nicoya Peninsula and Guanacaste

On Costa Rica’s Pacific side, the Nicoya Peninsula and Guanacaste region remain popular in September. While the rains are more frequent, mornings are usually sunny and perfect for exploring hidden beaches or enjoying yoga retreats.

The Nicoya Peninsula is also one of the world’s five Blue Zones, known for the longevity and well-being of its residents. Surf enthusiasts flock to towns like Nosara and Santa Teresa, while families can relax in Tamarindo’s calm waters.

Jaco: Surf and Nightlife

If you want a mix of surfing and vibrant nightlife, Jaco is a must-visit. September offers consistent waves for surfers of all levels.

When the sun sets, the town comes alive with music, beach bars, and fresh seafood. While quieter than the peak dry season, Jaco still offers a lively experience for those who want action beyond the beach.

Manuel Antonio and Beach Vendors

The Manuel Antonio National Park is especially beautiful in September, with lush rainforests teeming with monkeys, sloths, and tropical birds.

The beaches inside the park are among the most stunning in Costa Rica. As you stroll along the sand, you’ll meet beach vendors in Manuel Antonio selling coconuts, handmade jewelry, and local snacks—adding a cultural touch to your visit.

Caribbean Side: Limón and the South Caribbean

September is one of the best times to explore Costa Rica’s Caribbean coast, particularly Limón and the South Caribbean. Unlike the Pacific side, the Caribbean often enjoys drier weather during this month.

Towns like Puerto Viejo and Cahuita offer reggae vibes, Afro-Caribbean culture, and incredible cuisine like coconut rice and rondon stew. The beaches here, such as Playa Cocles and Punta Uva, are perfect for swimming, surfing, and snorkeling.

Parque Nacional Tortuguero: Sea Turtle Nesting

If you want a truly unique experience, head to Parque Nacional Tortuguero in September. This region is world-famous for sea turtle nesting, especially green turtles that lay their eggs under the moonlight.

Guided night tours let you witness this extraordinary natural event while learning about conservation efforts. The park itself is also known as “Costa Rica’s Amazon” thanks to its network of canals and rich biodiversity.

Islas Murciélagos and Isla del Coco

For adventurous travelers, September is a great month to experience world-class diving. The Islas Murciélagos, located in Santa Rosa National Park, are known for encounters with bull sharks and giant manta rays.

Meanwhile, Isla del Coco (Cocos Island) is a UNESCO World Heritage Site and one of the best dive spots in the world. Here, divers can spot hammerhead sharks, dolphins, and other marine life in pristine waters. These destinations are remote but worth it for diving enthusiasts seeking unforgettable experiences.

Tortuga Island Day Tour

Looking for a day trip? A Tortuga Island Day Tour is a popular excursion in September. Departing from Puntarenas or Jacó, the tour includes snorkeling, kayaking, and relaxing on white-sand beaches.

The calm waters around the island are ideal for spotting tropical fish, making it one of the best spots for a family-friendly adventure.
