You step off the sand into warm, glassy water that roars silently beneath the surface; a reef crest appears as a darker ribbon offshore, where instructors clip tanks and check gauges. In Puerto Morelos the sea feels immediate: current tugs at your fins, parrotfish graze on compact corals, and a wall of turquoise stretches toward the horizon. This is a Discover Scuba (DSD) introduction — a guided, shore-based program that turns first-time breath-holding into relaxed, regulated breathing underwater.

History
The Puerto Morelos Marine Reserve protects a stretch of the Mesoamerican Barrier Reef, reflecting decades-long efforts to balance fishing traditions with conservation.
Conservation
The reef is vulnerable to warming and pollution; operators enforce no-touch rules and recommend reef-safe practices like avoiding pre-dive sunscreens and not touching coral.
Reserve your spot on the Discover Scuba today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Skip lotions before the dive
Do not apply sunscreens or lotions before entering the water — they harm coral and reduce your instructor’s ability to assess skin reactions; wear a rashguard instead.
Bring a waterproof ID and medical info
Carry ID and note any medical conditions on your health questionnaire; some heart or respiratory issues may disqualify you.
Plan for calm-morning departures
Choose a morning slot for flatter seas and better visibility if you’re prone to seasickness or new to open-water entries.
Don’t fly soon after diving
Avoid air travel for at least 18 hours after diving to reduce risk of decompression sickness.
Swimsuit and quick-dry towel
Comfortable swimwear and a towel are needed for gearing up and drying off after the session.
Rashguard or wetsuit top
Protects skin from sun and scrapes; better than sunscreen before the dive and often provided if needed.
