From the promenade at Pantai Teluk Penyu you can watch fishing boats work the water while the walls of Benteng Pendem sit half-swallowed by grass a short walk inland. Cilacap is a working port town on Java's southern coast, and its sights are tied to that maritime history rather than polished for display.
This guide suits travellers who are already in Central Java and want a stop that mixes Dutch colonial remains, a long brown-sand beach and a boat crossing to an island that was closed to the public for most of the twentieth century. It covers the main sights in and around the town, plus how to string them together if you have a single day.
Top things to do in Cilacap
1. Benteng Pendem
Benteng Pendem is an abandoned Dutch fortress built in stages between 1861 and 1879 to defend the port of Cilacap. After a series of changes in ownership it fell into disrepair in the 1960s, and it was opened to the public in 1987. The pentagon-shaped site covers 6.5 hectares and includes original buildings such as barracks, a clinic and a prison, along with several later additions.
It sits near Pantai Teluk Penyu, so the two combine naturally in one outing. Allow time to walk the whole perimeter rather than just the central structures.
2. Pantai Teluk Penyu
Pantai Teluk Penyu is a brown sand beach close to the centre of town, lined with restaurants, many of them serving grilled fish, as well as souvenir stalls and hotels. Fishing is a popular pastime here, and the beach fills with local residents at weekends. Boats can be rented, and water activities such as banana boats are available.
Every Satu Suro, the first day of the Javanese calendar, residents hold the Sedekah Laut ritual, giving alms to the sea in thanks for protection while fishing. A procession leaves the office of the regent of Cilacap and heads to the beach, where water buffalo heads and other offerings are thrown into the sea by fishermen; by local tradition this must be completed by noon. Cultural activities follow, including wayang shows, kuda lumping dances and musical performances.
3. Pantai Karang Bolong
Pantai Karang Bolong is a white sand beach on Nusa Kambangan Island. The island was first used as a prison during the Dutch colonial period, declared a restricted area in 1905 and closed to the public; it stayed restricted under the Dutch colonial and later Indonesian governments until 1996, when the governor of Central Java and the Minister of Law signed a memorandum opening the eastern end of the island, including beaches such as Karang Bolong. Its lack of visitors, a consequence of its proximity to the prison, leaves the beach relatively unspoiled.
To get there, rent a boat from Pantai Teluk Penyu and cross the Segara Anakan Strait to the small Karang Bolong Dock on the north-eastern part of the island. From the dock, a one-kilometre trek follows a dirt path through forest, and transport is also available. Near the Karang Bolong fortress the path splits: turning left to the north leads to the western edge of the beach, a small stretch on the north of the island, while continuing straight through the fortress leads to the larger stretch on the eastern edge.
4. Nusakambangan
Nusakambangan is the island that shelters Cilacap harbour, best known as the site of several high-security correctional facilities, though there are hopes it can be developed as a tourist hub. It also shielded Cilacap from the worst of the 2004 tsunami. The eastern end of the island, opened to the public in 1996, is where you can reach beaches such as Pantai Karang Bolong.
Access is by boat from Pantai Teluk Penyu. Because much of the island remains restricted, plan your visit around the beaches on the eastern end rather than attempting to move around freely.
5. Widara Payung
Widara Payung is one of the beaches in the town of Cilacap, named alongside Pantai Teluk Penyu as among the most popular. Like Teluk Penyu, it lies adjacent to shipping activity, and the water is somewhat fouled from leakage from vessels docked nearby.
Treat it as a place to sit and watch the coast rather than to swim. It works well as a quieter alternative when Teluk Penyu is crowded at weekends.
6. Segara Anakan Bay
Segara Anakan Bay is the water between Cilacap and Nusakambangan, and it is the strait you cross by boat to reach Pantai Karang Bolong. Heavy sedimentation from the Citanduy River, which lies on the border of Ciamis Regency and Cilacap Regency, has been shrinking the bay; a new canal from the Citanduy through Ciamis Regency, exiting at Nusawiru near Pangandaran Beach, was agreed to address it.
You will see the bay from the water on any boat trip to the island. The crossing itself is part of the experience, so choose a clear part of the day for the views back towards town.
7. The harbour and port area
Cilacap is a sea port on Java's southern coast, and one of only a few on that coast able to service shipping of reasonable tonnage; the nearest safe anchorage east is Pacitan. The harbour is protected by Nusakambangan, and the port is a hub for national and international trade.
Combine a look at the working port with the beach and fortress nearby, since all three sit close to the centre of town. Keep in mind that leakage from docked vessels is what affects water quality at the adjacent beaches.
8. The town's Banyumasan culture
The town of Cilacap offers several tourist attractions highlighting Banyumasan culture. The local Javanese dialect is Banyumasan, and Javanese and Sundanese are the languages used in the regency, though most people can speak Indonesian.
The clearest way to encounter this culture is through events tied to the calendar, above all the Sedekah Laut ritual at Pantai Teluk Penyu on Satu Suro, with its wayang, kuda lumping and musical performances.
If you only have one day
Morning: Start at Benteng Pendem, walking the pentagon-shaped site and its barracks, clinic and prison while the day is still cool. Continue on foot to Pantai Teluk Penyu next door and follow the beach past the restaurants and souvenir stalls.
Afternoon: Rent a boat at Pantai Teluk Penyu and cross the Segara Anakan Strait to the Karang Bolong Dock on Nusa Kambangan. Trek the one-kilometre dirt path through the forest, then take the branch through the Karang Bolong fortress to the larger stretch of Pantai Karang Bolong on the eastern edge of the island.
Evening: Return by boat and eat grilled fish at one of the restaurants along Pantai Teluk Penyu. If your visit falls on Satu Suro, the Sedekah Laut procession and the wayang, kuda lumping and musical performances that follow will shape the whole day, so plan around them.
Frequently asked questions
How do I reach Pantai Karang Bolong?
Rent a boat from Pantai Teluk Penyu and cross the Segara Anakan Strait to the small Karang Bolong Dock on the north-eastern part of Nusa Kambangan Island. From the dock, walk the one-kilometre dirt path through the forest, or take the transport that is available.
When is the best time to see the Sedekah Laut ritual?
It is held every Satu Suro, the first day of the Javanese calendar. A procession leaves the office of the regent of Cilacap and heads to Pantai Teluk Penyu, and the offerings must be thrown into the sea by noon, after which wayang shows, kuda lumping dances and musical performances take place.
Can I swim at the beaches in town?
The water at Pantai Teluk Penyu and Widara Payung is somewhat fouled from leakage from shipping vessels docked adjacent to them. Fishing, boat rental and water activities such as banana boats are the usual ways to use Teluk Penyu.
Why was Nusa Kambangan closed to the public?
The island was first used as a prison during the Dutch colonial period and was declared a restricted area in 1905. It remained restricted under the Dutch colonial and later Indonesian governments until 1996, when the governor of Central Java and the Minister of Law signed a memorandum opening the eastern end of the island to the public.
Decide whether your trip falls on Satu Suro, then build your days around the fortress, the beach and the crossing to Nusa Kambangan.
