La Fortuna Waterfall, a stunning cascade plunging into a refreshing pool at the base of a lush rainforest, is a must-see attraction in Costa Rica. Access to the falls involves descending approximately 500 steps, which can be challenging for those with mobility issues, but handrails are available. Solo visits are common, but guided tours offer valuable insights into the area's ecology and history. The waterfall is open year-round, but the dry season (December to April) offers the best weather. Expect to spend 2-3 hours at the site. The entrance fee is approximately $18 USD per person.
