    Sunset and swim in the plancton

    Barbara_N, Mar 2026
    We had a boat with two tourguides on our own. The sunset was stunning and the fruits, they offered, very sweet. We could see the glittery plancton and could swin in it. It was amazing!

    Seems a bit shady at first glance but once the sun sets and the waters turn beautiful and sparkling, it became an unforgettable experience

    Not worth your time or money

    Please don't waste your money, the bioluminescent is nothing like it appears in the pictures. You basically pay for a 2hour boat ride around the bay, which is fine but don't expect to be dazzled by the algae, they are practically not visible. I would not recommend this to anyone.

    Amazing...

    Amazing experience.....Loved it!!! So much better than expected..a lovely cruise under the stars culminating in a once in a lifetime luminescent ocean experience we were able to play in

    Not as per label but still lovely

    The bioluminescence was wonderful despite some strange hiccups - we were meant to have an English guide but our guide didn’t speak a word of English, and didn’t even introduce himself! Still we had a beautiful night.

    Cool experience, just as expected, would recommend!

    We had a great time swimming and boating around. Our driver even found a stingray to show us once we were safely back in the boat on the way home. It was a good experience overall.

    Swimming in the the sky full of stars

    Katja_H, May 2022
    This was the most magical experience ever! We went out with the boat short before sunset und while we waited on the water for the dark our guide explained the area on Nicoya Peninsula and the phenomenon of the Bioluminsecence and has some fresh fruit. The guide was a real Tico with his heart deeply connected to the land and the ocean. And the when it was dark enogh we could see it!!!! We went into the water and it felt like swimming in an interactive sky full of glitzering neonblue stars. So magical!

    O passeio é interessante...

    O passeio é interessante e vale a pena, Os funcionários são simpáticos e atenciosos. As marés podem invalidar a saida do barco, confirmar sempre com geiko a saída. A experiência é interessante mas não é "como nos filmes!" Os locais e o tempo da viagem irão variar consonte o guia e as marés .

    Totalmente recomendable

    Una tarde fantástica. El capitan Slater magnífico con todas explicaciones Jairo y su esposa Flor encantadores. Fueron muy cercanos, y hasta nos dieron la oportunidad de hacer algo de esnorquel. Y la bioluminiscencia es para no perdérselo! Te dan agua y fruta fresca en el tour. No se puede pedir más. Ahhh y gracias por las pipas...
