If you're not a fan of huge resorts and big hotels, Isla Mujeres is the perfect getaway from Cancun.
Just catch the ferry to the island located 13km to the northeast of Cancun. The ferry ride in itself is enjoyable, as you float over shallow reefs and turquoise water.
Once on Isla Mujeres, I recommend staying near North Beach with its white sand and abundance of bungalow accommodations. Rent bikes and pedal around the entire island and be sure to make your way to the lighthouse crawling with iguanas.
