I wouldnt spend the money on this place again. People from Cancun come over on boats and kind of pollute the experience. We stayed on the island and would rather have just gone to playa norte for the day.

We snorkled at Garrafon de Castilla in May 2013 and had the best experience. Great snorkling for first timers or experienced. Buy the fish food, so much fun to feed the fish and have them swim all around you. Food and drink service as well as comfortable seating on the beach. Low key and tons of fun. Very inexpensive to...

This out-of-the-way beach is the best on IM by far, with shade, sand, waves, marine life, and never a crowd. Avoid the bland Playa Norte and come to a real Mexican beach, with excelent snorkeling, if you go out a ways, plenty of shade from adjacent boulders and trees, and great sand. It is quiet, and a nice glimpse of... More

down the rocky road...next to the state run park...50 pesos to get in..snorkle, eat ..swim ..and old hotel but you can see what isla was like 40 years ago..really cool

The snorkeling at GC is average at best. Most of what you will see are the seargent major fish and a few parrot fish. It is nice that you are not required to wear a life jacket or buoyancy device like at the neighboring garrafon park, so you are free to dive down underwater. The shore is a bit rocky... More

Three stars for the facilities, which though basic are well-maintained, clean and overall pleasant to be in, with nice views and plenty of choices for shady or sunny spots to hang out. One star for the snorkeling. The water was warm and clear, but there was nothing to see -- literally. A few fish here and there, mostly in the... More

A good alternative to Garrafon park as you can snorkel here for just 50 pesos. You will need to swim out a ways to see different fish as the ones closest to shore are the same. Worth a stop if your carting around the island.

We went to Garrafon Park the first day then to Garrafon de Castilla the next. I would rather pay the extra money and enjoy all inclusive Garrafon Park with ziplining, kayaking, snorkeling, bike riding, food and drinks for $49 vs Garrafon de Castilla for $5. If you are looking for a basic beach to snorkel and pay for your own... More

Just a warning--I LOVE MEXICO however next time I will buy Sea Safe off of Amazon and USE IT--My sister and I have sea lice and it itches like CRAZY---This park is GREAT for snorkeling and very reasonable. The sea lice are very prominent in the Spring months--this is my 5th time to Isla and the first time I have... More
