Spectacular sinkhole of karst origin among the highest altitudes of this tour

The Pulo di Altamura is a sinkhole of karst origin of the bowl type, created by the channeling of rainwater right at this point. This created a more or less circular depression with a diameter of about 500 m. with a maximum depth of 75 meters. Along the walls, which are very steep in some points, caves and ravines have been created which indicate the different levels of excavation by the waters. These caves represent a real archaeological heritage because they were inhabited since the earliest ages of prehistory. The route includes an unpaved stretch of about 1 km that can also be easily covered by racing bike.

One of the most beautiful naturalistic places in Puglia. The view is breathtaking from every perspective; it can be easily reached by MTB. It is preferable to explore it on foot due to the cavities dug in the ground and the considerable presence of stones that make the MTB experience quite impervious.

The Pulo di Molfetta is a characteristic karst collapse sinkhole located about 1.5 km from the center of the city of Molfetta, in a south-west direction, created by the collapse of the vault and dividing walls of one or more caves and tunnels formed starting from distant geological times and forming part of a complex karst system consisting of the confluence and intersection of several karst wells which originated precisely in that place from a series of geological coincidences.

The Bari region, particularly Puglia, features diverse natural 'canyons' primarily formed by karst erosion. These include vast inland sinkholes like the Pulo of Altamura, deep ravines such as the Gravina di Laterza, and dramatic coastal cliffs with sea caves found in areas like Polignano a Mare. These formations offer unique geological features and varied landscapes.
Yes, several canyons in the region hold significant archaeological and historical importance. The Pulo of Altamura, for instance, is a sinkhole with steep walls containing caves and ancient hermitages, showing evidence of human habitation dating back over 5,000 years. Similarly, the San Martino Cave is a site linked to karst phenomena of considerable historical and archaeological importance, opening on the low reliefs of the Murgia.
For hiking and exploring, the Alta Murgia National Park, home to the Pulo of Altamura, offers panoramic paths and rugged landscapes. The Terra delle Gravine Regional Natural Park, where the Gravina di Laterza is located, also provides well-marked trails catering to various fitness levels, allowing visitors to explore the canyon rim and surrounding hills. You can also find trails like the Lama Baronale Trail (Via di Annetta).
While many canyon areas offer rugged terrain, there are options for families. The Pulo of Altamura has panoramic paths suitable for walks, and the Gravina di Laterza features trails for all fitness levels. For a coastal experience, Polignano a Mare offers boat tours to explore sea caves, which can be an exciting family activity. Always check specific trail conditions for suitability with children.
The best time to visit the canyons in Bari is generally during the spring (April to June) and autumn (September to October) months. During these periods, the weather is milder and more pleasant for outdoor activities like hiking and exploration, avoiding the intense heat of summer and the cooler, potentially wetter conditions of winter. Sunset is particularly recommended for its dramatic lighting on the red earth and rock cavities at locations like the Pulo of Altamura.
Yes, the canyons, especially the Gravina di Laterza within the Terra delle Gravine Regional Natural Park, are excellent for birdwatching. This protected area is rich in biodiversity and is home to various bird species, including golden eagles and kestrels. The unique micro-habitat at the bottom of the Pulo of Altamura also supports diverse flora and fauna, including various bird species.
You can expect to see a variety of unique natural features. These include vast karst sinkholes like the Pulo of Altamura with its steep walls and ancient caves, deep limestone ravines such as the Gravina di Laterza, and numerous karst caves like the Curtomartino Cave and San Martino Cave. Along the coast, areas like Polignano a Mare feature dramatic cliffs and sea-carved grottos, including the Ardito Cave and Horseshoe Cave.
Beyond hiking, the Bari region offers various outdoor activities. You can find excellent road cycling routes, with options like the 'Bari, Conversano, and Polignano a Mare Loop.' There are also numerous running trails, including city loops and longer routes like the 'Peucetian Way.' For off-road adventures, consider gravel biking, with routes such as the 'Aqueduct Bridge – Curtomartino Cave loop'.
Yes, Polignano a Mare offers a unique coastal 'canyon' experience. The town is perched atop jagged limestone cliffs that plunge into the Adriatic Sea, with the sea carving numerous caves and inlets. You can explore these sea caves, such as Grotta Palazzese, Grotta Azzurra, and Grotta Arcivescovado, by boat. The iconic Lama Monachile beach, nestled between two high rock walls, is also a must-see coastal feature.
The Gravina di Laterza, located within the Terra delle Gravine Regional Natural Park, is considered one of Europe's deepest and most impressive canyons. This massive limestone ravine, carved over millennia, stretches 12 kilometers long, up to 400 meters wide, and features vertical walls reaching 200 meters in height. It's significant for its breathtaking landscapes, rich biodiversity, and numerous rock-hewn villages and ancient rock-cut churches.
While the larger sites are well-known, the region also features other interesting karst formations. The Pulicchio di Gravina is another natural monument worth exploring. Additionally, the Pulo di Molfetta offers a combination of natural monument, cave, and historical site, providing a glimpse into the region's diverse geological and cultural heritage.
