Sunset Boat Tour & Bioluminescence Adventure at Los Arcos Islands

This evening boat tour combines two things in a single outing: a Pacific sunset over the Bay of Banderas and a swim or float in bioluminescent water at the Los Arcos islands. It runs about 180 minutes and is limited to small groups of a maximum of 11 guests, which the operator says keeps the experience personal and relaxed.

It begins on the beach, where you meet your guide and receive a welcome drink (about 45 minutes). Then the boat moves through the Bay of Banderas for roughly 60 minutes while the sun goes down, the sky takes on warm colors and the sea darkens around you. The operator describes this stretch as a calm transition between the daytime cruise and the night portion.

Next comes the main event at Los Arcos de Mismaloya, a protected marine sanctuary known for its rock formations and sea arches. As natural bioluminescence appears, the water glows blue with each movement. You can observe it from nearby or swim in it, with a local expert guiding the group in low light so the glow stands out against the rocks (about 60 minutes). The light is created by microscopic plankton, in an area away from crowds and city lights.

The last leg, about 15 minutes, returns to Vallarta with the city lights seen from the sea. The tour ends at the pier of Los Muertos beach, in the Zona Romantica.

The tour suits all fitness levels, though it is not recommended for travelers with poor cardiovascular health. Bring a towel and a sweater, since it gets chilly, and wear a bathing suit under comfortable clothing with sandals or sneakers. A life vest is provided. The price covers all fees and taxes and carbonated and alcoholic beverages. The listing also lists public transportation as included, which seems unusual for a boat tour, so confirm the details with the operator when booking.
