This is a full-day introduction to gravel riding around Cadiz, built on wide riverside tracks. The route covers 34 km with about 250 m of climbing in total, so the effort stays low and there are no sustained ascents to worry about. The surface is broad and forgiving, which gives you space to learn how a gravel bike behaves: how it feels when the tyres move a little under you, how to brake on loose ground and how to hold a line.
Because the distance is short for a full day, the pace leaves room for stops, questions and practice. Nobody is trying to test your legs.
It sits at the gentle end of the Ride Cadiz range. The Cadiz Forest Gravel Loop covers 72 km with moderate climbing, and the Cadiz Volcano Gravel Day is a serious 88 km effort. This ride is the one to book first if you have never left tarmac on a bike, or want to try gravel before committing to a bigger day.
