You can find La Caleta just north (some 2 miles) along the coast from Chacala Beach and some 8 miles from Las Varas, Nayarit. On good days La Caleta offers waves that are the length of a football field, as well as being situated to hold any size of swell.
The bigger it gets, the cleaner the ride. Caleta is well known by surfers all over Mexico, and slowly also the rest of the surfing world!
You can get there by panga, it's a short trip from the little marina in Chacala, by land you'll need a 4 wheel-drive vehicle (rough terrain) and if you're very energetic, as some of the younger local surfers, you can walk through the jungle, though it is a fairly long hike, at least an hour, carrying your board, so think it over before you start off.
La Caleta, Nayarit: great surfing spot
From La Caleta, 400 yards to the South, toward Chacala Beach is yet another break, called Colorine, and this is one of the best wave rides in Nayarit, another left with fast waves over fairly shallow water.
