Choosing between Hidden Beach and La Nopalera depends on your physical ability and budget. Both beaches sit within the Islas Marietas National Park, but access rules differ entirely.
How do the swimming requirements compare?
You must swim 80 meters in open water to reach Hidden Beach.
Park rules require a life jacket and helmet for the Hidden Beach swim. Strong independent swimming skills are mandatory. La Nopalera does not require swimming through a cave. Visitors simply swim a short distance from the boat to the sand.
Which tours visit both beaches?
Most general eco-tours visit La Nopalera, but you must book a specific permit tour for Hidden Beach.
Only 116 people can visit Hidden Beach each day. Tour operators charge higher prices for this access. Standard eco-tours stop at La Nopalera and other snorkeling spots without the extra crater permit.
Are there age limits for either beach?
Yes, Hidden Beach restricts access to visitors between 10 and 65 years old.
Children under 10 or 12 cannot swim into the crater. Seniors over 60 or 65 are also restricted. La Nopalera has no strict age limits. Families with young children should choose tours that stop at La Nopalera instead.
How long can you stay at each beach?
Park rangers limit Hidden Beach visits to 15-20 minutes.
This strict time limit prevents overcrowding inside the small crater. Tours usually allocate 30 to 45 minutes for La Nopalera. This gives you time to swim, walk the shore, and explore the short nature trail.
