By Michael Henriquez López | Finca Curubanda, Curubande, Guanacaste The best time to visit La Leona Waterfall in Costa Rica is generally December through April, when drier weather usually brings more manageable river crossings and less muddy trails. For a quieter start, we recommend an early morning departure. The first tour with Finca Curubanda begins at 7:30 a.m. The rainy season can also be a rewarding time to visit, provided river conditions allow the tour to operate. Bef
