Napa Valley Paddle (NVP) rents kayaks, stand-up paddleboards, and inflatable paddleboards by the hour, day, and weekend. But the company—base on the Main Street Dock at Riverfront Plaza—also offers guided tours that offer a completely different perspective on a part of wine country that so many visitors see only by land. There are four such trips, including a two-hour paddle around the Oxbow River in downtown Napa; a four-hour fishing excursion from downtown Napa to the top of San Pablo Bay; and a day-long adventure through the marshlands south of Napa and the San Pablo Bay National Wildlife Refuge (both are prime spots for bird-watching). Tours include all equipment (including a personal flotation device and a waterproof bag to keep wallets and cell phones dry), as well as a brief safety lesson. NVP can also orchestrate casual “unguided” tours of downtown, complete with maps and gourmet picnic lunches, or family-friendly excursions on inflatable stand-up paddleboards that are big enough for six paddlers at once. All tours and rentals are subject to weather conditions, so it pays to call ahead.
