Bioluminescence and sunset by boat to Los Arcos de Mismaloya

This is a late-afternoon boat outing that combines a sunset with a swim in bioluminescent water, in the Los Arcos marine park near Mismaloya. The operator describes the park as an important marine life sanctuary in Puerto Vallarta. The outing lasts about 150 minutes.

You start by meeting your guide and enjoying a complimentary drink, and once the group is complete you walk to the dock to board the boat. The ride takes you along the south bay with panoramic views of the mountains and the sunset. Along the way you stop at a beach for a swim while you wait for night to fall.

The boat then continues to the marine park, known for its islands and caves where you can swim. The itinerary says you will spot seabirds such as frigates, pelicans and blue-footed boobies, and the listing dedicates about 60 minutes to this stop. When it is completely dark, you can jump into the water and swim, watching the water glow through bioluminescence. The operator does not promise the effect, and the wording used elsewhere is that they hope night falls at the beach, so the show depends on conditions.

Snorkeling equipment and bottled water are included, along with the complimentary drink at the meeting point. The operator recommends a high level of physical fitness, since you will be swimming in open water in the dark. It is not recommended for travelers with spinal injuries, poor cardiovascular health or who are pregnant.

The listing does not list exclusions or a specific meeting address, only that the meeting takes place where you get your complimentary drink. Confirm the exact point and time when you book. Public transportation options are available nearby.
