Top things to see and do in Diu
Diu Fort (Fortim do Mar's big sibling). The great Portuguese fortress on the eastern seafront is the island's defining sight. Begun in 1535 and expanded over the following decades, it was held by a Portuguese garrison right up to 1961, and it remains a hugely atmospheric ramble — double sea-walls and a tidal moat, bastions studded with old iron and bronze cannon, a lighthouse, ammunition stores, and long ramparts with sweeping views over the Arabian Sea and back across the town. Part of the complex historically served as a jail. It is one of the more evocative colonial forts in India precisely because it is left relatively raw. Entry is generally free or nominal and it is usually open through the daylight hours; verify timings and any fee before visiting. Allow at least an hour, wear sun protection, and mind the unfenced drops.
Panikotha (Fortim do Mar / Fortress of the Sea). Out in the channel on the northern, sheltered side of the island stands Panikotha, a lonely ship-shaped sea-fort rising straight from the water. Built by the Portuguese to guard the creek, it once held a small chapel dedicated to Our Lady of the Sea and a lighthouse, and it is floodlit at night to striking effect. You cannot walk to it — it is reached by boat, and short excursions run from the town jetty in season. Confirm boat availability, timings and fares locally; verify before visiting, and note that trips are weather-dependent.
St Paul's Church. The finest of Diu's churches and the only one still in active use for worship, St Paul's was completed in 1610 and dedicated to Our Lady of the Immaculate Conception. Its Baroque façade and, above all, its elaborately carved wooden interior — one of the most ornate of any Portuguese-era church in India — make it the standout piece of religious architecture on the island. It is a working church, so visit respectfully and quietly, especially around Mass times. Entry is free; dress modestly.
St Thomas Church (Diu Museum). A short walk from St Paul's, the Gothic-styled St Thomas Church was deconsecrated and converted into a museum in 1992. Inside is a collection of old statuary, wood carvings, inscriptions and artefacts salvaged from the Portuguese era, set in the cool, high-ceilinged shell of the former church. It is a quick but worthwhile stop that ties the town's history together. There may be a small entry fee; verify before visiting.
Naida Caves. Just outside the eastern city wall lies one of Diu's most photographed spots — a labyrinth of interconnected caverns and passages left behind where the Portuguese quarried the island's soft stone to build the fort and town. Shafts of light fall through gaps in the rock, cut steps thread between chambers, and the whole place has a sculptural, otherworldly quality that photographers love. It is easy to reach and free or nearly so; verify before visiting, wear grippy shoes, and take care on the uneven, sometimes slippery, surfaces.
Gangeshwar Temple. About 3 kilometres southwest of town, near Fudam village, this is Diu's most distinctive Hindu site — a small seafront shrine set among the rocks where five Shivalingas sit in a natural sea-cave and are washed by the tidal waves at high tide. The setting, with the sea surging around the lingams, is genuinely memorable and quite unlike a conventional temple. Visit around a rising tide for the full effect, watch your footing on the wet rocks, and be mindful of the sea. Entry is free.
INS Khukri Memorial. On a hillock above the coast, facing the sea, stands the memorial to INS Khukri, the Indian Navy frigate torpedoed and sunk off Diu on 9 December 1971 during the Indo-Pakistani War — the only Indian warship lost in war since Independence. A scale model of the ship is displayed in a glass enclosure, and the site honours the 194 sailors and officers who went down with her, including her captain, Mahendra Nath Mulla, who chose to remain aboard and was posthumously awarded the Maha Vir Chakra. It is a quietly moving spot with fine sea views. Entry is free; treat it as the war memorial it is.
Nagoa Beach. The island's main tourist beach, on the southern shore near Nagoa village, is a broad, horseshoe-shaped sweep of sand fringed with palms — including the branching Hoka palms that are something of a Diu emblem, often said to have been introduced by the Portuguese. This is the hub for water sports — parasailing, jet-skiing, banana-boat and speedboat rides, with camel and horse rides along the sand — and the liveliest of Diu's beaches. The curving bay makes for relatively sheltered swimming, but currents can still be strong, so heed local advice and lifeguard flags where present.
Ghoghla Beach. On the mainland side of the bridge at Ghoghla, this long, clean, wide beach is the largest in the Diu area and has been developed to a high standard, earning international recognition for cleanliness and facilities. It is calmer and more spacious than Nagoa, with gentler swimming and a more relaxed feel, and it works well for families. Water sports operate here too in season.
Jallandhar, Chakratirth and the sunset points. Closer to town, Jallandhar Beach is a quieter, less commercial stretch overlooked by a small hilltop shrine, while adjacent Chakratirth Beach is one of the island's classic sunset points, with a viewing area on the headland. For solitude, the remote Gomtimata Beach at the island's western end offers wide, empty sand and serene sunsets, though facilities are minimal and swimming demands caution. Watching the sun sink into the Arabian Sea from one of these western points is a fixed ritual of any Diu evening.
Zampa Gateway and the old town. The main historic gateway into the walled town, the Zampa Gateway, is worth a look for its carved stone figures — lions, angels and a priest — set above the arch, and it makes a natural starting point for a wander through the Portuguese quarter. Simply strolling the old streets, with their tiled houses, wooden balconies, small squares and sea glimpses, is one of the best free things to do in Diu. Add the town lighthouse and the seafront promenade to round out an easy half-day on foot.
