Nature lovers really enjoy the Lucaya Park & Beach Tour. The 40-acre park is filled with mangrove, pine, and palm trees. It also contains one of the loveliest, most secluded beaches on Grand Bahama, a long, wide, dune-covered stretch of sandy beach reached by following a wooden path winding through the trees. As you wander through the park, you'll cross Gold Rock Creek, fed by a spring from that is said to be the world's largest underground freshwater cavern system. There are 36,000 entrances to the caves -- some only a few feet deep. Spiral wooden steps have been built down into two if the caves and they are quite a unique and interesting sight. The pools in the caves are composed of 2m (6 1/2 ft.) of fresh water atop a heavier layer of salt water. The freshwater springs once lured native Lucayans, those Arawak-connected tribes who lived on the island and depended on fishinfor their livelihood. They would come inland to get fresh water for their habitats on the beach. Lucayan bones and artifacts, such as pottery, have been found in the caves, as well as on the beaches. You will learn a lot about the rich history of Grand Bahama on this tour and I guarantee you will fall in love with Gold Rock Beach. This tour is available for purchase onboard Discovery Sun at the Tour Desk for just $25, the same tour will cost you $40 on the island. If you are venturing out to the park on your own remember there is a $3 admittance fee for the park, however they do not accept payment at the park. You will need to purchase your admittance ticket ahead of time from the Rand Nature Center, which is the only place admittance can be purchased. If you are visiting the park as part of an organized tour through Discovery Cruise Line, your admittance will be included.
