La Leona Waterfall stays open 365 days a year, rain or shine. However, rainfall levels directly change the trail conditions and the famous blue water. Choosing the right month ensures you get the experience you want.
When is the water the bluest?
The water is the brightest turquoise from January through April during Costa Rica's dry season.
Volcanic minerals give the river its vivid blue color. During the dry months, the lack of heavy rain keeps dirt from washing into the canyon. This means the water stays clear and highly photogenic. The river currents are also at their calmest, making the swimming sections much easier.
When is the trail the safest?
The 4-kilometer (2.5-mile) hike is safest and least muddy between January and April.
You will hike over natural dirt paths and scramble over volcanic rocks. In the dry season, the ground is firm and offers better traction. The tour involves holding ropes against the river current. Lower water levels in the dry season make this physical challenge much easier.
Can you visit during the rainy season?
Yes, tours run year-round, but you should book a morning slot during the rainy season.
Afternoon rain storms are common from May through December. Booking an early morning tour helps you avoid heavy downpours. Extreme weather, such as lightning or severe flooding, can cause delays or cancellations for safety reasons. Heavy rains can also temporarily turn the blue water brown with mud.
Dry season vs. rainy season at La Leona Waterfall
The dry season provides clear trails and blue water, while the rainy season brings higher water levels.
Review the seasonal differences before you book your mandatory guided tour.
What time of day is best to go?
Morning tours are generally best to avoid crowds and afternoon rain.
Because the hike takes 2.5 to 3 hours, starting early guarantees you finish before typical afternoon weather changes. It also gives you time to drive back to towns like Tamarindo, which are 1.5 to 2 hours away.
What happens if it rains during my tour?
The tour operates in normal rain, so you will get wet regardless.
You are going to swim through a river canyon, so getting soaked is part of the experience. Guides monitor the weather constantly. If there is a flash flood risk or lightning, they will delay or cancel the trip. Remember to pack a waterproof dry bag for your phone and snacks.
