Tekek is the administrative heart of Tioman. The airport, police station, hospital, government offices, and mosque are all here, along with a few well-stocked shops and an internet cafe. If you need to sort anything practical on the island, this is where you do it. The whole village sits inside the Marine Park, and the entry fee is collected at a small office near the jetty.
The only paved road on Tioman runs south from Tekek to Berjaya Tioman Beach Resort. Heading north, the road narrows to a concrete path that you can cycle along (rent a bicycle in Tekek for around RM5 an hour) as far as Air Batang. Skip the moped rentals — the path includes stairs at the headland between Tekek and Air Batang that you cannot ride over.
For a proper adventure, take the jungle trek from Tekek over the spine of the island to Kampung Juara on the east coast. The trail passes through dense rainforest and a waterfall, and takes roughly two hours each way. Renggis Island, just offshore, is the most accessible snorkelling and diving site on the west coast.
