Two miles north of Cape Santa Maria is the Columbus Monument, commemorating Columbus's landing on Long Island. The road to the monument is off the Queen's Highway, and while the sign is often not visible, any Long Islander will gladly give you directions. The 3-mi treacherous road is too rough for vehicles without four-wheel drive, and most rental car companies won't let you drive it without an SUV, yet it is an extremely long hike. At the end of the road is a steep hill, called Columbus Point, and a climb to the summit affords a spectacular vista. This is the highest point on Long Island, and the second highest in the Bahamas. Farther north on Queen's Highway is Columbus Harbor, on Newton's Cay. Columbus made landfall in this cove, protected by limestone outcroppings. The more adventurous can follow the beach to the left, where a rough walking path leads to three other coves; each one a delight. Two coves up you will find sea glass scattered on the beach like sparkling jewels, and by climbing through limestone formations, you will discover another cove perfect for snorkeling.
