Taxi
Free port shuttle to Mahahual; licensed taxis at the pier stand
A free shuttle runs the 3 km between the port complex and Mahahual's malecón roughly every 15–20 minutes during ship hours. Licensed taxis queue at the pier exit — fares are flat-rate by zone, posted at the taxi stand, and run roughly $5–8 USD per person to Mahahual, $80–120 USD round-trip private to Chacchoben. Confirm the price before getting in. There is no Uber or ride-share at Costa Maya; the taxi cooperative has the route locked up.
Currency
USD widely accepted; pesos sometimes get you a better rate
Mexican pesos (MXN) are the official currency, but Costa Maya runs on US dollars in practice — the port complex prices in USD, Mahahual happily accepts both. Cards work at established businesses; carry $40–60 USD in small bills ($1, $5, $10) for taxis, tips, beach vendors, and street food. Skip the on-pier currency-exchange counters — rates are poor. ATMs exist in Mahahual but bank-branded ones are scarce; pull cash before the ship if you want pesos.
Day trip
Chacchoben Mayan ruins (50 min inland) — the standout excursion
Chacchoben is the cruise-day excursion to take if you want to leave the port. INAH-administered Mayan site, opened to public in 2002 after extensive restoration. Three pyramids on a circular jungle path, roughly 50 minutes' drive inland. Site hours are 9am to 3pm, and ship-sponsored tours pace the timing safely; independent drivers run roughly $80–120 USD round-trip. Skip Bacalar lagoon (4+ hours of driving) and the Sian Ka'an biosphere reserve (logistics impossible) on a cruise day.
Dock
Purpose-built cruise pier — alongside, no tendering
Costa Maya was built for cruise ships from scratch. Two berths handle up to four ships simultaneously on a long pier directly into the port complex; no tendering, walk-off straight into the shopping and pool village. The pier is exposed and can close in heavy weather, which is the one operational risk: a handful of skipped calls happen each year when swell makes berthing unsafe. Royal Caribbean took over port administration in July 2025 and plans to convert the property into a private destination called Perfect Day Mexico, scheduled for 2027.
Dive sites
Mesoamerican Reef close-in; Chinchorro Banks for serious divers
The Mesoamerican Reef sits a short boat ride off Mahahual — easy snorkel territory, plenty of cruise-ship excursions hit it. Banco Chinchorro, the Caribbean's largest atoll-style reef, is roughly 30 km offshore and a real dive destination, but the round-trip plus dive time eats most of a cruise day and is rarely a feasible independent booking. For most ship calls, stick with a half-day reef snorkel out of Mahahual.
Beach clubs
Port-complex pools (free) or Mahahual malecón clubs ($25–45 USD)
The port complex has multiple swimming pools with swim-up bars, included with the day — no booking required. For an actual ocean beach, take the shuttle to Mahahual where beach clubs along the malecón sell day passes in the $25–45 USD range, typically with a food-and-drink credit. Sargassum (Caribbean seaweed) blooms unpredictably from May through September and can leave any beach buried for a week at a time; check a recent sargassum tracker the morning of your call.
