Cenotes (Riviera Maya)

A cenote is a sinkhole where the limestone roof of the Yucatan's flooded cave aquifer has collapsed, opening a window into the water table. The Riviera Maya between Playa del Carmen and Tulum sits on top of two of the longest known underwater cave systems on the planet: Sac Actun, measured at about 372km, and Ox Bel Ha at about 542km as of 2026.

Typical trip cost

$$–$$$

$2,000–4,000 to over $4,000

Per person, excluding international flights.

  • Cenote diving is sold per dive or as a two-tank day, not by the week.
  • Guided dives commonly run about $85-130 USD each; a two-tank cenote day from Tulum or Playa del Carmen typically lands around $160-225 USD including guide, tanks, gear, transport and entrance fees.
  • Pickups from Cancun, or trips to farther sites like Angelita, push toward $250-300.
  • Cenote entrance fees are charged separately at the gate by the landowner or ejido and run roughly 250-500 MXN (about $14-29 USD) per cenote: Casa Cenote around 250, Chac Mool around 300, Dos Ojos around 350, The Pit around 500.
  • Large cameras usually cost an extra 150-500 MXN.
  • Check whether the quoted price includes entrance fees; operators split on this.

Sources & last checked

Checked July 2026

Research is source-backed, but conditions and fees should still be confirmed locally.

Note on the data: Site coordinates are approximate — taken from the general position of each cenote off Highway 307 and the Coba road, not surveyed dive-site GPS. Entrance fees are landowner-set and change without notice; the MXN figures come from operator blogs in 2025-2026 and should be treated as indicative. Depth figures for Dos Ojos conflict between sources (8-10m on the standard cavern lines vs a generic 18m Open Water limit quoted by others); the shallower line-specific figure is used. Cave system lengths cited from the Quintana Roo Speleological Survey via Guinness World Records (Sac Actun, 371.96km as of July 2019) and CINDAQ reporting for Ox Bel Ha (541.79km, April 2026). No month-by-month visibility or temperature data is published, so the season is coded year-round rather than invented. A widely-reported May 2026 crocodile bite at Casa Cenote was dropped: it rested on a single local outlet and could not be cross-checked, so only the sourced safety guidance is kept. Water temperature: Cenote water is freshwater from the filtered aquifer, not sea, and holds a near-constant 24-25C (about 75-77F) in every cenote every month; most divers wear a 5mm or 7mm because you cool down slowly over a 45-60 minute dive. Access: Cancun International (CUN) is about 1 hour to Playa del Carmen and roughly 1.5-2 hours to Tulum by road; cenotes are then 10-30 minutes off Highway 307 and entered from steps or a platform, with no boat crossing.
