🔎 TL;DR
- Akumal Bay is federally protected since 2016 — only licensed-guide tours can enter the snorkel zone legally.
- Year-round resident green-turtle population. Sightings are 95%+ reliable every month.
- Strict rules: max 6 guests per guide, 45-minute water cap, no-touch, no-chase, no-feeding.
- Avoid unlicensed beach "guides" — they are illegal and damage the bay. Fines for guests entering without a license.
- Best time: morning (less crowded). Year-round operation.
Why Akumal is regulated
By the early 2010s, Akumal Bay was overrun. Hundreds of unlicensed snorkelers a day were chasing the resident green-turtle population, touching them, blocking their breathing path. Turtle stress markers rose; some moved out of the bay. In 2016 Mexico's CONANP (the federal protected-areas agency) declared the bay a regulated snorkel zone with strict rules and a permitting system.
Since then, the turtle population has stabilized. The rules are the reason the experience still works year-round. Following them is non-negotiable.
The rules — in plain English
- Licensed guide required. Every snorkeler must be part of a guide-led group. Solo entry to the protected zone is illegal.
- Max 6 guests per guide. Smaller groups are common — never larger.
- 45 minutes in water max. Strictly enforced. Operators rotate groups so the bay isn't overloaded.
- 2 m minimum distance from turtles. No exceptions. Don't swim toward, follow, or trap.
- No touching, period. Even brushing accidentally is prohibited.
- No feeding. Stress and dependency.
- Biodegradable sunscreen only. Regular sunscreen damages reef and turtle health.

When to go
- Year-round. Resident population — they're not migrating through. Sightings high every month.
- Best time of day: early morning (8–10 AM). Calmer, fewer guests, water clearer.
- Avoid late afternoon in peak season — water can get crowded.
- Best months: Nov–Apr (drier, lower humidity). Summer months work but afternoon storms more common.
Avoid the unlicensed "beach guide" trap
You will be approached on the beach by unofficial guides offering cheaper tours. Don't accept. Reasons:
- They are illegal — entering the protected zone without a CONANP license is a federal violation.
- You can be fined as the guest (not just the guide).
- They don't enforce protocols. Damage to turtles directly.
- The "savings" is not worth the risk.
Licensed operators are easy to identify: they have CONANP credentials, fixed prices, and operate from designated entry points. Always ask to see the license before booking.
Bring
- Biodegradable sunscreen (regular not allowed)
- Towel + change of clothes
- Phone in a waterproof case if you want photos (your guide can shoot)
- Cash for tip — guides work hard
