Stand up paddleboarding, or SUP, is very popular in Sri Lanka. Several local companies offer excursions that explore different parts of the country. SUP is great for improving balance and core strength, it’s fast to learn and like long-boarding gives you a much better chance of catching a ride. You also have a much better vantage point watching the sets roll in. Sri Lanka has many inland rivers and lagoons that make an excellent adventure but check the local crocodile reports as they roam freely in parts of the backcountry.
