Every summer, the waters north of Isla Mujeres host the world's largest known whale shark aggregation, feeding on fish eggs near the surface. This is not an aquarium encounter. You are in open Caribbean water, alongside animals that can reach 12 meters in length, in their natural feeding behavior.
Nauty 360 picks you up at your hotel between 6:00–7:00 AM, then departs from Marina Punta Norte, Puerto Juárez between 7:00–7:30 AM. Each shift is 2 swimmers plus 1 guide — SEMARNAT regulation, non-negotiable. With 10 guests, everyone cycles through multiple turns before the return to your hotel at approximately 2 PM.
The experience is weather-dependent. If the port closes for weather, the tour reschedules. If the tour departs and there is no whale shark sighting, there is no refund or reschedule — sightings are not guaranteed.
Hotel pickup 6:00–7:00 AM → marina departure 7:00–7:30 AM → 35–50 min transit → 2–3 hrs in aggregation zone → ~2 PM return to hotel.

The math on private charters changes significantly above 6 guests. For most groups of 6–10, private costs the same or less per person as a shared tour — with full control of your water rotation.
| Option | Group of 2 | Group of 6 | Group of 10 | What You Give Up |
|---|---|---|---|---|
| Shared Group Tour | $140–$180 | $840–$1,080 | $1,400–$1,800 | Fixed rotation order, 20+ strangers, early cutoff |
| Private Charter — Nauty 360 | $2,500 total | $2,500 total | $2,500 total | Higher cost for very small groups (1–4 people) |
For small groups (1–10 people), a private charter costs more per person than a group tour — but you gain priority water rotation, 7:00–7:30 AM departure, and zero strangers on board.
Private lancha (up to 10 guests): $2,500/vessel + 6% management fee · $10/person marine park & dock fee (not included) · 50% deposit via PayPal to confirm · Port closures reschedule; no refund if no sighting · Confirmation in under 2 hours.
Mexico's whale shark regulations (NOM-059-SEMARNAT-2010 and the Cancún-specific CONANP management plan) exist to prevent the aggregation from collapsing — which it nearly did in the early 2000s when unregulated boat traffic harassed the animals and disrupted feeding. The current rules are strict and enforced on the water by CONANP inspectors.
