Highway 307 has two lanes on each side for traffic. There are no tolls to pay.
The exit for the city of Bacalar is on the left. The scenery is through the Sian Kaan Biosphere for part of the trip. The driving time from Cancun is 5 hours. Well worth the drive.
On foot or bicycle would be very doable if you are staying in the city of Bacalar, as well as taxis, which are not expensive.
The water of Lake Bacalar is among the most pale and gemlike blue that could possibly exist. The main attraction of traveling to this area is the lake, whose beauty could easily induce one to sit and read for a few days without regret. The lake is somewhat shallow at the shores, except where there are sinkholes commonly known as cenotes. It is well seen by kayak or sailboat. The sand when disturbed smells strongly of minerals or sulfur, though sitting by the lake or even being on the water certainly carried no odor whatsoever.
The Fortress de San Felipe Bacalar, in the center of town, represents one of the bastions used by the Maya before they were overrun by the Spanish, it has a small but modern museum inside, if you are in town it´s worthwhile visiting.
On Sunday night, there may be music and dancing in the city square.
Active Nature Bacalar  offers guided kayak/canoe trips, bicycle tours and jungle walks to explore the beautiful lake and its surroundings. They are located 5 km north of Bacalar at Villas Ecotucan which is also a really nice place to stay.
Ramón Aguayo is the certified scuba instructor in town, if you´d like to get certified. Ask for him at the front desk of Villas Bakalar or at the chinese house on the costera. Sailing boat rentals or instructor, as well as boat excursions are also available.
The mayan ruins nearby that are worthwhile visiting are Chacchoben, Dzibanché and Kohunlich. They don´t have a lot of people and the jungle surroundings are magnificent. Contact the front desk of Villas bakalar for birdwatching among jungles and ruins.
