The C-50 Shipwreck in Puerto Morelos is a dive that you cannot miss. This underwater jewel offers one of the best diving in the Riviera Maya, full of marine life and mystery that will leave you fascinated.
The C-50, also known as Juan Escutia of the Mexican Navy, is a Gunboat class ship that originally served the Mexican Navy. This 56 meter long vessel was deliberately sunk in 2000 to create an artificial reef, with the aim of promoting marine biodiversity and offering an additional attraction for diving tourism in the region.
The Juan Escutia C-56 wreck lies within the marine park at a distance of about 2 km from the coast.
You can reach from the port of Puerto Morelos with a boat ride of 15-20 min.
NOTE: The C-56 wreck is often confused with the C-53 wreck, the Felipe Xicoténcatl (USS Scuffle AM-298), which sank in the same manner only a few kilometers away in Cozumel. Both ships are the same type of minesweeper.
