Snorkeling at Los Arcos Marine Park

Probably the best place to snorkel in Puerto Vallarta is Los Arcos (the arches), which has been a National Marine Park since 1984.

The rocks can be seen from downtown PV, but you’ll need to take a boat ride to get there. The water isn’t super-deep, and there aren’t necessarily the picturesque tropical scenes that you might see in the waters of the Caribbean or Hawaii.

But there are some colorful fish and reefs, as well as lots of birds flying overhead. During my visit, folks from the boat threw some bits of bread to attract the fish to the surface. Score!


While I was there, two or three other boats stopped by, so there were maybe 30 or 40 people in the water at a time. The boats tend to keep a bit of distance between themselves and the rocks, but if you swim closer to the rocks, you can find more fish.


The arches themselves are fascinating. I didn’t see any boats go through the passages, but kayaks and canoes could easily pass underneath the rocks.


After several minutes, a few of us starting feeling minor stings on our skin. My first thought was jellyfish, but I didn’t see anything in the water, and the stings were just like pin pricks, not as painful as I’d imagine a jellyfish sting to be. Maybe they were little tiny invisible relatives of the jellyfish. They weren’t all that bothersome, especially with the skin cream folks on the boat had brought.

I did not have a fancy GoPro or other thousand-dollar camera with me. What I did have was a Walgreens brand disposable 27-exposure waterproof camera. And the film inside was actually expired – because I’d originally bought it for the snorkeling trip in the Florida Keys that got rained out three years ago.

So there was no guarantee the pics I took with it would even come out. They did – but they came out the way you’d expect photos from an expired Walgreens disposable underwater camera to come out: blurry and grainy.

Here’s a small selection of the amateur underwater pics I took, starting with the best one – a close-up of a pretty large fish. Hey there, fella!

  1. Puerto Vallarta has always been our top diving and snorkeling destinations. It’s absolutely to die (and to dive for too), so seeing photos of people who are enjoying its beauty gives me that feeling that I’m one with the universe and this universe I’m talking about is absolutely magnificent.
