Hudson River Expeditions operates kayak and stand-up paddleboard tours from three Hudson Valley locations: Cold Spring, Beacon, and Staatsburg. The company partners with Constitution Marsh Audubon Center to offer guided paddles through the 270-acre sanctuary, where naturalists help identify bird calls and explain marsh ecology. History-focused tours with Putnam History Museum cover Revolutionary War sites, Cold Spring's 19th-century industrial heritage, and Indigenous history along the river. Specialized offerings include a 4-hour waterfall tour through Constitution Marsh to a secluded freshwater waterfall with wading pool, and the Bannerman Castle Loop, a fast-paced 3-hour paddle past Breakneck Ridge and Pollepel Island for experienced paddlers. All tours include boat rental, paddle, water, and personal flotation device. The company also offers kayak and paddleboard rentals and instruction for paddlers of all skill levels.
