Embark on a scenic 3-hour bike tour led by a nature guide to discover the characteristics of the Alta Murgia National Park. Meet your guide at the Gravina di Puglia train station, get equipped with your bike and helmet, and begin your exciting journey which takes place partly on asphalt and dirt paths. Follow a loop that runs through ancient sheep tracks in some of the wildest and most fascinating places in the park until you get to Pulicchio di Gravina, the second-largest sinkhole in the Alta Murgia National Park. Enjoy the wide scenery of the Bradano Valley that separates Puglia from the high mountains of the Lucanian Apennines. After the visit to Pulicchio, an exciting descent into a wooded canyon awaits you before you set off back to the city.
