A rocky cove on Otranto’s northern coast, known for its large semi-submerged cave. Today the visit must be planned around cliff-safety rules first: maritime restrictions linked to landslide risk are listed for this stretch of coast.
That is no longer responsible without checking current rules: the nautical guide lists restrictions on bathing and other activities within safety distances from the cliffs in this sector of Otranto.
The cove cuts into the calcarenite cliffs north of Otranto. Small sand or gravel deposits may occur, but the setting is mainly rock and usable space is limited.
More as a coastal landscape and nature stop than a comfortable conventional beach.
The 2026-updated P7 nautical guide still lists bans, within variable 30–50 metre distances from the coast, on bathing, navigation, stopping, fishing and underwater activities in several Otranto cliff sectors, including the stretch reaching Grotta Monaca and the nearby Canalone.
Check signs, buoys and current orders. If the sector is restricted, view the cove from land and stay out of the water.
The cave is registered as Pu 152 in the Apulian Cave Register. A 1999 speleological study describes about 110 m of mainly horizontal development; later inventories give about 100 m.
The old “80 metres deep” wording was misleading: this refers to internal cave development, not vertical sea depth.
A 2001 study recorded a breeding colony of about one thousand Miniopterus schreibersii in the large sea-filled chamber, then the largest documented nursery for the species in Puglia. We cannot assume the colony is the same size today.
Avoid noise, bright lights and approaching roosting areas.
Local tradition links the cave’s name to Mediterranean monk seals said to have used these waters in the past. We found no site-specific scientific evidence supporting a current stable presence.
Keep the traditional explanation without turning it into a zoological certainty.
Grotta Monaca features on routes from Otranto through Staffa, Cafaro and San Pietro dei Canali. The surface is largely dirt and rock, and approaching cliff edges requires care.
Stay on clear paths and respect fences, warning signs and safety distances.
Descriptions mention sandy bottom in some sectors beneath the cave and rock along the margins, with cavities and changing depth.
Never use the seabed’s appeal as a reason to enter a restricted bathing or diving zone.
Paths, cliffs, limited space and possible restrictions make this unsuitable for a simple beach day with young children.
Choose an authorised, easy-access urban beach in Otranto for swimming.
With landslide-prone cliffs and maritime restrictions, encouraging jumps is no longer appropriate.
Do not jump from the cliffs and do not enter restricted water, even if other people do.
Grotta Monaca is naturally interesting, but cliff-safety orders may prohibit underwater and surface activities inside the safety zone.
Confirm the permitted perimeter; choose another authorised coast sector if necessary.
Even outside restricted areas, waves on the cliff make approach, exit and small footholds less safe.
With waves, strong wind or poor visibility, remain on the path and enjoy the view.
We do not promise a specific public car park for Grotta Monaca. In 2026 Otranto municipal parking is charged from 1 April to 31 October; private parking may also exist nearby, with conditions to be checked.
Walk from town if appropriate; if driving, use authorised parking only.
No public beach facilities are guaranteed in the natural cove. Bars and accommodation nearby are separate private businesses.
Bring water, hat and sun protection even for a walking-only visit.
We found no assisted-bathing service specifically at Grotta Monaca. In 2026 the municipality instead runs Otranto Inclusive Beach at Gradoni with boardwalks, beach wheelchairs, accessible changing rooms and assistance.
For mobility needs use the equipped Gradoni service and treat Grotta Monaca as a viewpoint only if the path is suitable.
Guided northern-coast routes include Grotta Monaca in 6 or 12 km walks across dirt paths, rock, Mediterranean scrub, coves and caves.
Wear suitable shoes, carry water and keep away from cliff edges; weather can alter the route.
Walkers, photographers, geology and nature enthusiasts, and visitors wanting to see one of Otranto’s notable sea caves while respecting restrictions.
Today we recommend it mainly for landscape, cave and walking, not as an invitation to swim.
Anyone wanting sand, a serviced beach, easy access with toddlers, guaranteed swimming, cliff jumps or snorkelling without checking orders and cliff distances.
For a conventional beach day use authorised Otranto beaches.
Walking shoes, water, hat, sunscreen, charged phone and binoculars or camera. Mask and fins only make sense after confirming the chosen sector is legally accessible.
Do not turn the visit into a sea entry if signs or orders prohibit it.

“Calamuri” is a real place-name south of Otranto, also confirmed by the Speleological Register through Vora Calamuri. No institutional boundary for a standalone beach was found, so the pin is an area reference rather than a certified sea access.
The historic guide also used the local name “Filu de Mienzu”. The maritime ordinance officially identifies “Spiaggia San Nicola” on the cliff southeast of the harbour and defines a restricted sea area because of landslide risk.
This central beach is also known as Spiaggia dei Gradoni: fine sand, free and serviced sections, with immediate access from the promenade.
An urban beach just north of central Otranto, with fine sand, generally shallow water in the sandy sections, free areas and nearby beach clubs: convenient if you want sea and town within walking distance.
Otranto’s white maritime light at Punta Craulo, north of the harbour, beside Porto Craulo beach and low rocky shoreline.
A small free cove north of Otranto between La Castellana and Canale del Càfaro, with a mixed sand-and-rock shoreline.
A small rocky inlet on Otranto’s northern coast, between Staffa and the coves towards Grotta Monaca: clear water, paths and steps for access, an interesting seabed for snorkelling and virtually no facilities in the cove itself.
Cattapìgnula means “bat” in local dialect; local sources describe a cave used by bats and a sea-accessed cavity. The pin is approximate for the coastal sector.

A large sea cave north of Otranto in the Mulino d’Acqua cave system, close to several neighbouring caves.
Sapunerò is a rocky landmark on Otranto’s northern coast, along the route between Grotta Monaca and Mulino d’Acqua; the pin is approximate because no standalone institutional coordinate was found.
A spectacular bay of cliffs, small inlets and sea caves. Today, however, the most important thing to know before you go is that sea access, bathing and remaining below the cliff are affected by safety restrictions.
Otranto’s famous coastal cave with a collapsed roof and a large opening to the sky, in the Mulino d’Acqua cave system.
A secluded rocky bay north of Otranto, between the Mulino d’Acqua sector and Torre Santo Stefano, commonly visited from the sea.
The ICCD cultural-heritage record describes Torre del Serpe as a coastal tower about 200 m from the sea and 35 m above it; tradition links it to an earlier lighthouse, while today it survives as a partly ruined structure.
A sea cave in Mulino d’Acqua Bay, immediately beside Grotta Sfondata and reached from the sea.
