Banda Aceh guide: the Grand Mosque, tsunami sites, coffee and local rules

Before you go: Sharia law, dress and conduct

Aceh received special autonomy under the 2005 Helsinki agreement and is the only province in Indonesia that formally implements Sharia law. The tourism ministry says this covers dress codes and public conduct. The UK government's travel advice (FCDO) says these laws apply to non-Muslims as well as Muslims. When we checked on 3 October 2026, the FCDO said that drinking, making and selling alcohol, gambling, extra-marital sex and same-sex sexual activity were all illegal in Aceh under Sharia law. Penalties can include public caning after a Sharia court process. It also mentioned reports of the Sharia police harassing foreigners.

In practice, plan a dry trip and dress conservatively across the whole city, not only in the mosque. Wear loose clothes that cover your shoulders and knees, and women should keep a headscarf to hand. Unmarried couples should be discreet. Daily life follows the prayer times, and the Friday midday prayer is the high point of the week. On Weh Island, for example, the ministry notes that Gapang Beach opens only at 2 pm on Fridays so that people can attend the prayer.

The Baiturrahman Grand Mosque

The mosque in the centre of the city is Banda Aceh's landmark, opposite the Blangpadang field. Its roots go back to the Aceh Sultanate. The tourism ministry's pages say the first mosque on the site dates from the reign of Sultan Iskandar Muda, and one gives 1612. The Dutch colonial army burned it down on 10 April 1873, during the Aceh War. The Dutch then rebuilt it between 1879 and 1881, in a grander Mughal-influenced style. More domes were added in 1936 and 1957, and the ministry describes the mosque today with seven black domes and seven minarets. It was one of the few large buildings left standing after the 2004 tsunami and became a refuge for survivors. The courtyard now has giant retractable umbrellas modelled on those at the Prophet's Mosque in Medina.

Come in the early morning or late afternoon, when the marble is cooler and the light is softer. Come back after dark if you want to see the mosque lit up. The ministry says modest dress is required. Women are expected to cover their arms and legs and wear a headscarf, and the mosque usually lends robes and headscarves to visitors who need them. Photography is allowed, but take photos quietly and never disturb people who are praying. Plan your visit between prayer times, and avoid the Friday midday prayer.

The tsunami memorials: museum and PLTD Apung

The Aceh Tsunami Museum on Jalan Sultan Iskandar Muda is a short walk or rickshaw ride from the mosque. It opened in 2009, designed by the architect Ridwan Kamil, and its wave-shaped building is meant to be walked through in order. You enter through a long, dark passage with water running down the walls. Next comes a chamber with victims' names inscribed on the walls, followed by dioramas, photographs, survivors' stories and a disaster-preparedness section. The roof is designed as an escape hill for up to 3,000 people. Treat the museum as a memorial: speak quietly, don't touch the exhibits, and don't come for photographs alone.

Opening details vary. When we checked on 3 October 2026, one ministry article listed opening every day from 09:00 to 16:00, with tickets at about IDR 10,000 for foreign visitors. Another said the museum is closed on Fridays and that entry is free. The museum's own website could not be read, so ask your hotel before you go. Avoid Friday, and allow about two hours.

In Punge Blang Cut, a few kilometres inland, sits PLTD Apung 1. This 2,600-tonne floating power plant was moored offshore when the tsunami carried it two to three kilometres into the city. It crushed two houses, killing the people inside. The site was later turned into a memorial park with a monument and walkways. Seeing a ship this big among houses shows the tsunami's reach more clearly than any map. Go after the museum, by ride-hailing car or rickshaw.

The Sultanate city: Museum Aceh, Gunongan and Kerkhof Peucut

Museum Aceh on Jalan Sultan Alaidin Mahmudsyah, near the mosque, was founded by the Dutch on 31 July 1915 as the Atjeh Museum. Its centrepiece is a Rumoh Aceh, the traditional Acehnese wooden stilt house, whose front veranda was for receiving male guests and back veranda for women. The ministry lists 1,856 objects in the collection, including Islamic manuscripts. When we checked, the ministry gave opening hours of 08:30–12:00 and 14:00–16:15 daily except national holidays, and admission of IDR 5,000 for adults and IDR 3,000 for children. Note the midday closure.

Close by, the Gunongan in Taman Sari is a white ornamental structure that, according to the ministry, Sultan Iskandar Muda built for his consort Putroe Phang, a princess from Pahang. The small domed gate called Pinto Khop once linked the garden to the palace. Also nearby, Kerkhof Peucut is the Dutch military cemetery from the Aceh War, where thousands of soldiers are buried. The Aceh War began in 1873 and the Dutch claimed victory in 1904, though resistance went on afterwards. Together with the mosque, these three sites tell the story of the Sultanate and the colonial war, and they can share one morning.

Coffee shops, sunset at Ulee Lheue and the beaches

Coffee is Banda Aceh's social life. Spend an hour in a traditional *warung kopi*, where the coffee is filtered rather than made with an espresso machine. Order a sanger, coffee with sweetened condensed milk, filtered repeatedly and shaken until it froths. The tourism ministry says the name comes from *sama-sama mengerti*, 'mutual understanding'. The beans usually come from the Gayo highlands around Takengon, and the ministry recommends Takengon for a proper coffee tour. In 2026, the city also held a Colossal Coffee Experience festival (18–20 September).

For the evening, Ulee Lheue beach in Meuraxa district, not far from the centre, is the city's sunset spot. The ministry lists parking, toilets, a prayer room and food stalls there. Lampuuk, about 17 km from the city, has white sand and beginner surf waves from November to March. The dress code applies on the beach too, so swim covered up, and only when the sea is calm.

Moving on: the ferry to Weh Island

Banda Aceh is the gateway to Weh Island (Sabang), with reefs and dive sites around Iboih, Gapang and Rubiah Island. Boats leave from the port at Ulee Lheue. The tourism ministry says the slow ferry takes a couple of hours and the fast boat about 45 minutes, and that ferries leave in the morning. Timetables change and the weather can affect sailings. Check the day's departures at the port or with your hotel before you plan the rest of the trip around them.

To combine Banda Aceh with Medan and North Sumatra, the tourism ministry suggests flying or taking the bus. Long-distance buses arrive at Batoh terminal, and ride-hailing cars, rickshaws (bentor) and minibuses run from there into the centre.
