Sportfishing on Lake Arenal

Spend a Day Fishing in the Calm Waters of the Biggest Lake in Costa Rica.

Lake Arenal sportfishing offers anglers of all abilities a great opportunity to combine stunning scenery with thrilling freshwater action in the shadow of the iconic Arenal Volcano. Local guides offer both half-day and full-day charters, with all necessary gear, snacks, and expert instruction included. The lake is best known for its rainbow bass (guapote), which is highly prized for its spirited fights and can grow to over 12 pounds. Other common catches include the hard-fighting machaca (which leaps like a mini-tarpon), mojarra (similar to perch), tilapia, and, on occasion, snook.

FAQs

Answering questions about this activity.

What type of fish are machaca and guapote?

Machaca is one of the most aggressive and hardest-fighting freshwater fish in Costa Rica, so much so they have earned the nickname ā€œmini tarpon.ā€ Related to piranha's, once hooked, they will leap out of the water several times. They typically aren’t considered table fare, but are often used in soups. 

Rainbow bass is part of the cichlid family, which includes oscars, wrasse, angelfish, and the closely-related peacock bass. Better known as ā€˜guapote’ in Costa Rica, they are the main target of freshwater anglers in this part of the world and are prized for their combination of intelligence and aggression (plus the meat is great-tasting!).

What are the best months to catch these fish?

Machaca can be caught all year round in Costa Rica. They primarily feed at the surface, so even if the water is murky, shallow, or deeper than usual, they will still hit your lure or fly if it makes a big enough splat.

Guapote can be and are caught all year round, but the fishing is typically better when the lake water levels are lower as they have less space to hide in. Those months would coincide with our dry season or summer, so typically, Jan-May is spectacular.
