Discover the vibrant underwater world of Los Arcos with a guided scuba tour in Puerto Vallarta. Perfect for lovers of marine life and authentic adventures.
Thinking about exploring the underwater beauty of Puerto Vallarta’s Los Arcos? This 6-hour guided scuba experience offers a chance to see rays, sea turtles, and a rainbow of nudibranchs in their natural habitat. It’s a popular choice for travelers eager to add a splash of adventure to their Mexico trip. While it’s not a full certification course, it’s designed for those who want a safe, guided, and memorable introduction to the region’s marine wonders.
What we love about this tour? First, the expert guidance from PADI Divemasters makes even first-timers feel confident — and safe. Second, the stunning underwater scenery—with tunnels, caves, and arches—creates a truly immersive experience. The only potential hiccup? If you’re not comfortable with water or have limited mobility, it might be worth considering. This tour perfectly suits travelers craving an active, nature-filled outing, especially those with some familiarity with snorkeling or diving.


This excursion offers an efficient way to see some of Puerto Vallarta’s best underwater sights without the fuss. The tour kicks off at 9:00 a.m., giving you plenty of time to enjoy the morning light. After a quick gear fitting and safety briefing, your day begins with the first of two dives at Los Arcos, one of the region’s most celebrated marine parks. The waters are famously clear, often providing visibility that makes the lush underwater scenery seem almost unreal.
The first dive typically involves inspecting the rocky slopes and exploring the tunnels and caves that give Los Arcos its name. Expect to see large rays gliding gracefully and maybe even a sea turtle or two, as many reviews mention how majestic these creatures appear. The rocky formations create natural tunnels and arches, perfect for snapping photos and marveling at how natural forces sculpted the seascape.
Once you surface, your guide and crew swiftly prepare the second tank. During this break, you can relax on the boat or soak in the scenery, often with a refreshing drink in hand. The second dive takes you to a different spot, offering new views and marine life. It’s a chance for those who love underwater photography or simply want more time among the fish to soak it all in.
