About the Beach The Hidden Beach is perhaps the most popular beach in Mexico - located in the Marieta Islands near Puerto Vallarta, the Hidden Beach can be considered a real ecological gem, as it was formed over several millennia by volcanic activity. The Hidden Beach is, just as it's name suggests, hidden: it is actually a hole in the ground, and at the base of the hole you can enjoy crystal clear waters and white, sandy beaches. This one-of-a-kind beach has managed to remain untouched by human hands and is protected from the outside world, as the only way to access it is through a very tight tunnel. As a matter of fact, this is what makes the Hidden Beach so unique in its complexity - you can only reach it by swimming, and only during low tide. It is extremely difficult to get to it unless you are a professional swimmer or diver. Visiting the Beach Thousands of curious tourists who want to enjoy "something different from conventional beaches as we know them" come here every year, especially those who are passionate about scuba diving and snorkeling. The virgin nature of the Hidden Beach coupled with the diversity of birds and marine life make this area a true masterpiece of nature. The Hidden Beach is a scenic travel destination and a popular tourist attraction, and once you lay your eyes on it you will fully understand why: imagine a whole in the ground, where you can see the blue waters and the bottom of the ocean even if is several meters deep. What can be more beautiful than swimming in these perfectly clear waters along with unique, wild marine life and enjoying the sandy beaches away from the hustle and bustle of the large cities? If you take a picture at the Hidden Beach, then this is undoubtedly a memory you will not forget too soon - many have referred to it as "Heaven on Earth", and for a very good reason. There is no better getaway than this fairytale-like beach, especially since it is not exploited at its fullest potential and you will not stumble upon tens of tourists if you come here. What makes this beach stand out from the rest of the Marieta Island is that it is completely isolated and, as mentioned above, it is extremely difficult to access the beach. Given the fact that Puerto Vallarta stays the same throughout the 12 months and nothing changes in terms of climate, you can visit it at any time. Nonetheless, it is highly recommended to visit the Hidden Beach during winter, after the rainy season - it is then when the waters of the Hidden Beach become clearer than ever. The Bottom Line To sum it up, the Island is protected given the wealth of endangered species found here, and although you do not need a license to approach the island, you do need a permit to set foot on the beach. There are plenty of companies in Puerto Vallarta that organize daily trips to the Island, leaving you plenty to chose from.
