Lake Arenal is famous for its beauty however it is not well known for its amazing Bass fishing. Typically any other time of the year you can pull about 5-10 good sized fish out of the lake. April-November is the best time of year to fish Lake Arenal as the water is low so there are the same amount of fish in a lower lake volume.
The lake is low so there are a lot of stumps and grass around where you will be able to find bass hiding ready to strike. The current biggest bass pulled from Lake Arenal was around 20lb, however typically they are around 3lbs. The Lake has both rainbow and tiger bass.
You can expect to catch around 20 bass this time of year, however this is never guaranteed. La Mansion Arenal Hotel can reserve the fishing for you with their local Costa Rican Fishing expert Gerardo. All gear can be provided if necessary as well.
