Lake Arenal is the country’s largest lake, a long reservoir that lies between the volcano and the rolling hills of Guanacaste, and it is one of the loveliest places in the region to spend an evening. The lake was created when a dam was built across the Arenal River in the 1970s, flooding the valley and the old town of Arenal, and today it supplies electricity and irrigation as well as scenery. Along its shores, wind turbines turn on the ridges, small villages and farms sit among green hills, and the volcano stands over the eastern end. The Moonshine Sunset Cruise on Lake Arenal, which we link, is a guided boat trip timed for the end of the day, when the light turns soft and the colours of the sky reflect in the water. It has around fifty reviews and a high rating. The pace is relaxed: you glide across calm water while the guide talks about the lake, the volcano and the wildlife, and you watch for birds such as herons, kingfishers and egrets, as well as the changing silhouette of the cone. It is an easy, gentle way to end a day of more active sights.
How it works
You book a date and show your ticket at the departure point, which is on the lake shore a short drive from La Fortuna. Cruises are scheduled to catch the sunset, so the exact time changes through the year, and the details of what is included, such as drinks, snacks or pickup, depend on the option you choose. Check the ticket and confirm transport if you do not have a car, since you will be returning after dark on rural roads, when a driver or shuttle is the safer choice.
What to expect
The boat moves slowly, with time to stand, photograph and relax. The best views are of the volcano and the lake, and in good weather the sunset can be spectacular; in cloudier conditions the mood is more atmospheric, with mist on the water. Wildlife sightings on the shore depend on the season and on the light.
The cruise is calm and quiet, with few demands on your fitness, which makes it suitable for most ages and mobility levels. It is not an adrenaline activity, so think of it as a way to pause and take in the scenery.
Making the most of it
Bring a light jacket, because it becomes breezy and cooler on the water at dusk, along with insect repellent and a camera or phone with a good low-light mode. Arrive a little early to choose a seat with a clear view of the volcano, and ask the crew which side of the boat gets the best light. Weather on the lake changes quickly, so keep a rain layer in your bag.
The cruise fits neatly into a day that includes the hanging bridges or ziplining on the lake side of the volcano, and it makes a pleasant, quieter alternative to an evening in the hot springs. Couples and families with older children tend to enjoy it most, and it is a particularly good plan for the evening of a day on the road, when you do not want to do anything strenuous.
