For a truly unique perspective on Seville, you have to get out on the Guadalquivir River. You can grab a paddleboard or a kayak and see the city's iconic sights, like the Torre del Oro and the Triana Bridge, from the water. It's a fantastic way to cool off and get some light exercise, and since the tours are guided and suitable for all levels, you don't need any prior experience to join in on the fun.
