The Los Arcos boat trip takes you to a small rocky marine park just south of Puerto Vallarta. Expect a 30-45 minute ride out, followed by snorkeling in relatively clear water among rock arches and small coves. Most trips stop at 2–4 spots, include guided snorkel time (gear provided), and often a brief beach landing or cliff-jumping opportunity. The full outing usually lasts 3–4 hours. It’s a solid half-day nature trip that’s scenic but not life-changing — good for families, couples, and anyone who wants easy access to snorkeling without a long journey.
Best time is November through April when seas are calmer and visibility is better. Summer and early fall bring warmer water but rougher rides, more jellyfish, and frequent cancellations due to swells. Expect to pay around $45–$85 per person depending on boat size, inclusions (lunch, open bar, smaller groups), and whether it’s a basic shared tour or a more comfortable catamaran/sailboat experience.
Pick a morning departure to avoid the afternoon wind and get better snorkeling light. If you’re prone to seasickness, choose a larger, more stable catamaran over a small speedboat. Skip the cheapest no-name tours that pack 40+ people — you’ll spend more time waiting in line for snorkel gear than actually in the water. Bring your own reef-safe sunscreen and a dry bag; the provided towels are usually thin and damp by the time you need them.
