About Alexandria Bay, New York

Alexandria Bay, a jewel in the Thousand Islands, unfolds with a rugged, watery beauty that speaks of ancient glacial hands and the relentless caress of the St. Lawrence River. It lies 80.5 miles north of Clay, NY (from Clay, NY: bearing 9°T), and is situated 2.1 miles north-east of Point Vivian. The landscape here is a dynamic interplay of granite outcrops, worn smooth by eons of wind and ice, and the ever-present shimmer of water. Islands, ranging from mere rocky humps to substantial, tree-clad havens, punctuate the expanse, creating a labyrinthine waterways where sunlight fractures into a thousand dancing pieces. The air, especially in the early morning or late afternoon, carries a crisp, invigorating tang, a blend of pine needles and the cool breath of the river, hinting at the distinct seasons that paint Alexandria Bay with vibrant, fleeting hues. This is a place where history flows as readily as the currents. Once a vital hub for early fur traders and later a booming hub for the timber industry, Alexandria Bay’s character is deeply intertwined with the St. Lawrence River’s power and bounty. The grand, Gilded Age summer cottages that still crown some of the larger islands are silent witnesses to a time when this region was a playground for America’s elite, drawn by the promise of recreation and the dramatic scenery. Today, the local economy thrives on tourism, with boat tours weaving through the islands, fishermen casting their lines for the legendary St. Lawrence bass, and the cheerful hum of summer visitors filling the air. Boldt Castle, a testament to a grand, unfulfilled love story, stands sentinel over the river, a romantic landmark that draws eyes and imaginations from across the globe.
