MUSA, Underwater Museum: What to Pack and Bring

The Cancun sun is intense, even on cloudy days. Sun protection is non-negotiable. Bring a wide-brimmed hat, sunglasses with UV protection, and a rash guard for extended time in the water, particularly if you plan to snorkel at MUSA, Underwater Museum.

Standard chemical sunscreens are harmful to coral reefs and marine life, so pack only reef-safe sunscreen. Many tour operators and parks, including those visiting MUSA, Underwater Museum, enforce this. Mosquito repellent is also crucial, especially during dawn and dusk, or if you plan to visit cenotes or archaeological sites like Chichén Itzá.

Consider a repellent with DEET for maximum effectiveness, or a natural alternative if preferred. A reusable water bottle is another must-have; staying hydrated is key in the tropical heat.

Your passport must be valid for at least six months beyond your planned departure date from Mexico. Before landing, you will receive an immigration form (FMM) to complete. Keep the small, stamped portion of this form with your passport; you will need it to exit the country.

Losing it means a trip to the immigration office at the airport and a fee. Quintana Roo, the state where Cancun and the MUSA Underwater Museum are located, also charges a tourist environmental tax. This can be paid online before you arrive or at the airport.

While the system is not always strictly enforced, it is best to be prepared.

While many places in Cancun accept US dollars, you will almost always get a better exchange rate paying in Mexican pesos. This is especially true for smaller vendors, taxis, and souvenir shops. ATMs are widely available, but stick to those inside banks or reputable hotels to avoid skimming.

Inform your bank of your travel dates to prevent card freezes. Tipping is customary in Mexico. While you can tip in US dollars, pesos are preferred and more convenient for the recipients.

Carry small denominations of pesos for tips, especially for bellhops, housekeepers, and tour guides at attractions like the MUSA Underwater Museum.

For resort wear, think light, breathable fabrics like linen and cotton. Swimsuits are essential, especially if you plan to visit MUSA, Underwater Museum or spend time at the beach or pool. For dinner, many resorts and upscale restaurants have a smart-casual dress code; men might need collared shirts and closed-toe shoes, while women often opt for dresses or dressy separates.

When visiting archaeological sites like Tulum or Chichén Itzá, comfortable walking shoes are paramount, along with sun protection. If you plan to experience the nightlife in the party district, more fashionable attire is common, but comfort is still key as you will be on your feet.

Always pack a light jacket or shawl for air-conditioned interiors or cooler evenings.

Do not drink tap water in Mexico. Stick to bottled water, even for brushing your teeth, to avoid stomach issues that can derail your trip to the MUSA Underwater Museum. Over-the-counter medications are readily available at pharmacies, often with familiar active ingredients but different brand names.

If you have specific needs, bring your preferred brands from home. For common ailments, pharmacies like Farmacias del Ahorro or Farmacias Guadalajara are widespread and well-stocked. Many even have a doctor on-site for minor consultations, offering a convenient option for quick medical advice without a full clinic visit.
