Larantuka is in Flores (Indonesia).
Few foreigners make it east past Maumere but Larantuka and the neighboring islands are well worth visiting.
The local language, Lamaholot, is spoken as is Bahasa Indonesia. Few people speak some English.
There are two ports in Larantuka, a big one in the center and a small one about five kilometers south of town. The big port serves Pelni ships, as well as other ferries. The small port serves neighboring islands, including West Timor, with ASDP ferries. Example: Larantuka - Kupang (West-Timor) with ASDP on Friday 1 PM for 70.000 rupia taking 15 hours. Example: Larantuka - Makasar (Sulawesi) with Pelni on Friday at 11 PM for 176.000 rupia taking 1.5 days. Pelni has a website. Most boats are late for a few hours or more. Busses connect Larantuka mainly with Maumere, and a few will go to Ende and further.
If you are coming from Alor to the east, you can reach Larantuka by taking the wooden boat (once or twice a week) from Alor to Lembata (Lewleba) from where there are daily boats to Larantuka that also stop on Adonara.
Bemos charge 2500 around town. Have the exact amount on you, otherwise good luck getting change. An ojek for a short ride can be as low as 5000rp (April 2014). Walking is also an option.
Easter is celebrated intensely, with a famous processing that draws thousands of locals. The tradition is of Portuguese origin (they have a prayer in Portuguese) and is a few hundred years old. On Easter Friday there is a procession of dozens of boats in the sea, following a canoe carrying a statue. If you want to join, try to get on a boat which is not too crowded (they are free, courtesy of the local government) as accidents happen.
In the evening there is a walking procession down the streets with thousands of people.
There are some ok beaches east of town. The current is very strong!!!
It's possible to climb Ile Mandiri, the mountain next to Larantuka. Or the twin volcano Lewotobi some distance on the way to Maumere. Gunung Bagging is the best source of information for climbing these and other mountains in Indonesia. If you like mountains, Ile Boleng on Adonara and Ile Api on Lembata are very interesting too. Adonara, Lembata and Solor are worth visiting and truly off the beaten track seeing very few foreign visitors.
Buses to Maumere depart the bus terminal west of Larantuka. Take a bemo from the corner next to the harbor in the center to get to the terminal (3000 rp). Pelni ferries and car ferries to Kupang and Makassar. Wooden ships (kapal motor) take passengers and motorbikes to Adonara two or three times a day (20000rp), Lembata two or three a day (40000rp) and Solor. From Lembata there is a boat once or twice weekly to Alor. Prices as of April 2014. There is an agency for Pelni tickets right next to the harbor. The actual Pelni office is east of the harbor on the main street on the left side.
