Fly from Ontario to Cancun

If you reside in Ontario and are interested in vacationing somewhere with both the opportunity to relax and explore an interesting history, then book a flight to Cancun, a city well known for its idyllic white-sand beaches and the Mayan ruins that fray its borders. When you fly from Ontario to Cancun, your flight will take six to seven hours. You can get to Ontario International Airport (ONT) through driving there on your own or by accessing public bus routes that lead to the airport.


Cancun is known for its beaches, but it has many hidden beauties as well. You can take a below-the-shore tour of the Cancun Underwater Museum, which features over 470 submerged statues from long ago. If you're one for scuba diving, you can throw on some gear and explore the underwater cave system of Cenotes Dos Ojos. To get an up close look at old, ruined Mayan cities, visitors can head over to Chichen Itza or Coba. For beach time relaxation, there is the Isla Contoy, a small island in Quintana Roo.

Hints and tips

When you fly from Ontario to Cancun, keep in mind when walking that in Mexican culture, pedestrians do not have the right of way. It is recommended that you allow cars to go first. The most convenient and inexpensive form of public transit in Cancun is its bus systems, but you can also walk or catch a cab. Cancun temperatures generally range between 80 degrees and 90 degrees Fahrenheit, so pack for warm weather.

Cancun When to Go

Prime weather in Cancun matches the worst weather months in most of the U.S.: November through February, with high season from mid-December through April, when temperatures are in the mid-80s and humidity is low. Be prepared to share the beach with plenty of fellow vacationers on school holidays, and to dole out more for hotels and attractions.

Cancun weather is typically warm and humid. Unless you’re really strapped from a budget or time standpoint, avoid hurricane season (August through October) and the rainy season during summer months. May through mid-December is considered low season, when prices drop from 10 to 30 percent. Some hotels charge higher rates in June and July, when Mexican, European, and U.S. families on summer vacations come to town. However, these rates are usually still lower than they are in the winter.

And just because Cancun has one of the craziest spring-break party scenes in the Caribbean doesn't mean it is bereft of cultural events. Dia de los Muertos (Day of the Dead) in late October/early November celebrates the lives of deceased loved ones and ancestors. This time-honored tradition that’s akin to Halloween dates back to the ancient Azetc and Mayan cultures, and is revered as one of Mexico’s most significant festivals. There are regional variations, with Cancun’s take flashing influences from ancient Mayan customs that have been combined with traditional Mexican ceremonies to create Hanal Pixan (the Mayan ritual of the dead).

Also count on crowds during spring break and Mexican national holidays that are religious (Holy Week and Easter) or freedom focused (Cinco de Mayo in May and Independence Day in September). If you can handle the masses, these are great ways to soak in true local flavor as nationals display their patriotic pride.
