Fortuna Waterfall, a magnificent 70-meter cascade near La Fortuna, Costa Rica, offers a refreshing natural pool for swimming at its base. Visitors can easily access it independently via a well-maintained trail involving approximately 500 steps downhill to the falls and uphill back, making it moderately challenging for those with mobility issues but generally accessible for most. While many organized tours to the Arenal region include a stop here, a solo visit is entirely feasible. The waterfall is open year-round, with the dry season (December-April) offering clearer waters, though it remains stunning during the rainy season (May-November). The approximate cost for foreigners is $18-$20 USD, and a typical visit duration, including the hike and time for swimming and relaxation, is about 2-3 hours. It's recommended to bring swimwear, water shoes, a towel, insect repellent, and water; changing rooms and restrooms are available, and proceeds support local conservation.
