West coast of Mexico at the north end of Troncones.
Go north of HWY 200 from Zihuatanejo to the sign for Troncones. Turn left (west) towards the beach. At Troncones turn north and keep going until you come to the lagoon of Boca de Lagunillas just past the small community of Majahua.
Wonderful area to paddle and lots of birds and other wild life.
Photographed this Stilt from my kayak in the lagoon just north of Troncones.
