Merida, Mexico

Merida (also known as the “The White City”) is the capital city of the Mexican state of Yucatan and largest city of the Yucatan Peninsula and the cultural and financial capital of the region. Located in the northwest part of the state, about 35 kilometers (22 miles) from the Gulf of Mexico coast, Merida is a modern, cosmopolitan city with museums, art galleries, restaurants, shops and boutiques. A major center of commerce, Merida is considered the crossroads of the region and one of the most important places to experience the Mayan heritage.

Merida is currently considered as the safest city in Mexico, and its crime statistics are very low, as compared to other cities in the country. In Merida, we can find a friendly environment that is mostly quiet and very relaxed. Merida was awarded City of Peace in 2011.
