If you’ve ever dreamed of floating beside a school of colorful fish amid stunning rock formations, the Puerto Vallarta Snorkel Adventure at Los Arcos might just be what you’re looking for. It’s a quick, well-organized trip designed to give you a glimpse into one of Puerto Vallarta’s most iconic natural sites without requiring a full-day commitment.
Two things we love about this tour are the accessibility to beginner snorkelers and the remarkable underwater scenery—from caves to arches that provide a sense of exploring a hidden underwater cathedral. The tour is also rated 4.4, suggesting travelers generally find it enjoyable and good value.
A consideration to keep in mind is its duration of three hours—while perfect for a quick escape, it might not satisfy those craving a more extended or diverse marine adventure. Still, for most, it offers a satisfying and relaxing way to connect with the ocean. It’s especially suitable for travelers who want a guided, safe, and visually rewarding experience that highlights Puerto Vallarta’s marine beauty.
