Arenal National Park in north-central Costa Rica is a breathtaking 30,000-acre expanse that combines the thrill of active geology with the lush beauty of tropical biodiversity. From rainforests to steaming hot springs, and even the elusive jaguar, the park offers a variety of natural wonders that make it one of the country’s most prized destinations. Visitors are drawn to its ever-changing landscapes, where volcanic activity has shaped the terrain into a dramatic showcase of Costa Rica’s dynamic environment.
The centerpiece of the park is the towering Arenal Volcano, standing at 5,357 feet and renowned as Costa Rica’s most active volcano. By day, smoke spirals from its peak, and by night, rivers of glowing lava illuminate its slopes. Nearby, the dormant Chato Volcano tells a different geological story. Thousands of years ago, its collapse formed a serene turquoise lagoon within its crater, creating a sharp contrast to Arenal’s fiery demeanor. Together, these volcanoes provide a glimpse into the region’s volcanic history and natural beauty.
Arenal’s geothermal activity is also responsible for its abundance of natural hot springs, making it a haven for those seeking relaxation. Tabacón Hot Springs, fed by a thermal river heated by the volcano, is a popular choice for its warm waters and natural ambiance. The terraced Titokú Hot Springs, nestled in vibrant gardens, offers a tranquil alternative. Before unwinding in the springs, visitors can explore the park’s numerous hiking trails, like the Las Coladas Trail, which meanders across ancient lava fields. At less than a mile round trip, it’s an easy hike that showcases the volcanic terrain and provides opportunities to encounter the park’s diverse wildlife, from howler monkeys to vibrant parrots. Although jaguars roam the park, their sightings remain rare and mysterious.
For those seeking adventure on the water, the rivers around Arenal National Park provide another perspective on the region’s splendor. Rafting on the Peñas Blancas River offers a leisurely journey, ideal for spotting monkeys, crocodiles, and sloths, while the Balsa River blends calm waters with thrilling Class II and III rapids. For adrenaline junkies, the Toro River’s technical Class III and IV rapids promise an exciting challenge. Whether it’s a serene float or a heart-pounding ride, these rivers add an aquatic dimension to the park’s exploration.
The best time to visit Arenal is during the dry season, which typically runs from December to April, when the weather is at its most pleasant. While the rainy season, spanning the rest of the year, brings heavy downpours—averaging 138 to 197 inches annually—it also enhances the lushness of the rainforest and fills the rivers to their brim. Regardless of the season, Arenal National Park offers a remarkable combination of relaxation, adventure, and awe-inspiring natural beauty, making it a must-see destination for anyone visiting Costa Rica.
