Bonaire's economy is mainly based on tourism. The island caters mainly to scuba divers and snorkelers, as there are few sandy beaches, while the surrounding reefs are easily accessible from the shore. Bonaire is world renowned for its excellent scuba diving and is consistently rated among the best diving locations in the world. Bonaire's license plates carry the logo Divers Paradise (in English). Bonaire is also consistently recognized as one of the best destinations for snorkeling. Wind surfers also make a strong group of island tourists, as the east side of the island (facing the Caribbean Sea) has the large waves and wind gusts needed for windsurfing. Lac Bay, in the south east, is shallow, yet windy, and hence is considered an excellent place for intermediate sailors to improve their skills. Tourism infrastructure in Bonaire is contemporary and based on time-share resorts.
