Cancún [1] is a coastal city in the tourist destination called The Mexican Caribbean, i.e., the state of Quintana Roo, on Mexico's Yucatan Peninsula. It is a popular vacation spot on the Caribbean coast.
Peak season in Cancun tends to run from December to April. Prices in both airfare and hotel increase dramatically during these times, while dropping in the summer and early autumn months. Late June is especially hot, so come prepared or try the off season. Hurricanes can be a major threat in late summer
Understand
Resting on the northeast corner of the mexican Caribbean, Cancun itself was built on a site selected as the ideal spot for a new tourist development by the Mexican government. The state of Quintana Roo was still a territory and this area had few inhabitants when Cancun was built. It is comprised of fourteen miles of pristine white beaches shaped like a number "7", home to Mayan archaeological wonders, turquoise seas, a bountiful underwater world, and world-class vacation amenities. It is still considered the gateway to the Mayan World ("El Mundo Maya"). Mayan temples and ritual sites are everywhere, some smothered by lush jungle, others easily accessible. Good tourist attractions.
The Cancun hotel zone is almost entirely built around the tourist industry. It abounds with all-inclusive resort hotels. Stay here only if you don't mind spending your vacation with many other tourists.
Downtown Cancun, especially once you get away from the ADO bus station and nearby hostels and hotels, is a real Mexican city. There are many restaurants, shopping centers, markets and clubs in the downtown area that you can visit during your stay.
Those mostly seeking beaches and scuba diving, or who are a bit adventurous, can easily find rooms on equally beautiful and less crowded beaches along the coast just an hour or two south of Cancun for much less than the cost of major Cancun hotels. Some Spanish language skills may aid in finding better deals. You can rent a car, or take the bus to Puerto Morelos (about 20 minutes) or Tulum (1 hour). Playa del Carmen (45 minutes, MXN$80) is between the two, but caters to the all-inclusive crowd. Taxis are also available.
Those looking for a base of operations who want good or luxury hotels and the advantages of urban life but prefer more local flavor may wish to stay in the Yucatan's main city of Mérida. Many international flights in to Cancun continue on after a stop to Mérida's international airport.
Get in
One of Cancun's best features is its transport links, as most major air carriers in North, Central, and South America, have service to Cancun. There are some extremely cheap charter flight deals available from the UK (from around £100) as well as commercial flight deals from several European carriers.
The hardest part of the journey to Cancun (aside from your initial airport check-in) is getting from the luggage carousel to your transportation. Make sure you know who your transport is and find them on the outside, as that is where they will be! Unless you are looking for a timeshare, free meal or looking to burn time and money on your vacation don't stop to chit-chat about booking tours and such. There is plenty of time for that after you get settled in. After you clear the red or green light baggage inspection, do not give your bags to any locals offering to carry them. They will either demand money to carry them 15 meters or steal your luggage.
Get around
Cancun is very easy to navigate. To the South is the airport, to the North is the city and in between on the stretch of land between the sea and the Nichupte lagoon are all the hotels, beaches and bars, referred to as the hotel zone or Zona Hotelera. Downtown is where most residents live and it stretches in on the mainland behind the lagoon.
See
Interactive Aquarium — Right in the middle of the hotel zone, this small but modern aquarium lets you get up close and personal with aquatic life. You can pet rays, nurse sharks, touch starfish, etc. There is also a chance to swim with dolphins in a large pool. Water and sand — Cancun is possibly best known for its beautiful turquoise waters and powdery white beaches. Isla Contoy, it is about 30km north of Isla Mujeres and apart from its natural beauty it is considered to be the most important nesting place for sea birds in the Mexican Caribbean with more than 150 different species.
Drink
Cancun's nightlife is unlike any other destination on Earth! For some, a day in Cancun doesn't start until tasks like an 11AM breakfast, nap on the beach, and siesta are arduously completed. This is your place to shine.
