Whether you’re a seasoned snorkeler or a first-timer, this trip promises vibrant coral reefs, lively marine life, and unforgettable scenery. We find it particularly appealing because of its accessibility and connection to nature, but keep in mind that it’s a 3-hour outing, so if you’re craving a full-day adventure, you might want to look elsewhere.
One aspect we especially love is the focus on protected marine ecosystems—no fishing or anchoring around Los Arcos helps ensure the environment stays healthy and vibrant.

It’s designed for travelers who enjoy natural beauty and want a straightforward, well-organized outing. The 3-hour duration is perfect for fitting into a busy schedule, whether you’re on a cruise or have other activities planned.
The price of $123 per person strikes us as reasonable, especially considering all the gear, guides, and the boat ride included. It’s a good value for those curious about marine environments but not wanting to spend a fortune. The tour is rated 4.4 out of 5, which indicates many satisfied travelers, though some mention that the experience can vary depending on weather and group size.
