The port of Carloforte is located halfway along the east coast ofSt. Peter Island sheltered from the prevailing west winds.
The small port is protected by the Health Pier to the north and the San Vittorio Pier to the south.
Within it are two concrete piers used for commercial traffic and docking of ferries and floating docks operated by various companies.
The port offers 600 berths of which 50 are for transit for boats up to 50 meters in length.

The port is sheltered from all winds; strong Sirocco, Mistral and Libeccio winds can cause undertow.
There is a fuel station at the quay in the fishing harbor.
Water and power outlets, slipway, slipway, mobile cranes up to 70 t, 70 t travel lift, shore storage, hull and engine repair are available.
Supermarkets, grocery stores, hotels and restaurants can be found in the vicinity of the ports.

In the area in front of the ports and in the St. Peter channel the seabed is 2.7 to 5 meters therefore the approach is rather tricky.
A 1.5-meter deep shoal is located east of the mouth signaled by a north cardinal cylindrical buoy and a south cardinal spindle buoy.
Boats with a draft greater than 2.5 meters are required to follow the two access alignments based on light signals and buoys the first of which leaves the shoal to the south, the other to the north.
From here one heads to the South-Southwest shore of the ports where there is a pyramidal meda with black and white stripes and a white one placed on the hill behind to then access the harbor.
If you arrive at night landmarks are a yellow light at the end of the shoal, a steady red light placed on the pyramidal meda and a flashing red light placed on the second meda.

San Pietro Island is located about 10 km from the coast and forms together with the island of Sant’Antioco and other nearby islets the Sulcis Archipelago.
I litorali dell’isola alternano spiagge sabbiosi come La Bobba o Guidi a calette rocciose come Cala Fico. Carloforte is the only inhabited center on the island.
The pastel-colored facades of its buildings, Baroque churches and narrow alleys that crisscross it are reminiscent of some small town in Liguria. Carloforte’s cuisine bears material witness to its history and is affected by the contamination of Ligurian tastes with Arab flavors.
