Tonsai Bay is the bustling heart of Phi Phi. The bay hosts Phi Phi Island's main village, and it is the main arrival port in Phi Phi. Here, there are no cars or roads, only footpaths. The village is located on an isthmus, for which Phi Phi is famous, with Tonsai Bay on the south side and Loh Dalum (Dalum Bay) on the north.
Before 14:30, when the last ferry leaves, the streets are busy with daytrippers and people arriving/departing. After that, the island is more relaxed and the difference is tangible. In the evening the streets fill again with diners looking for a place to eat. Additionally, as most business is done at night, the tour shops, dive shops and every other kinds of shop come to life. Later on, some isolated nightlife areas heat up; especially on the east side of the village and of the bay.
Phi Phi is a very bohemian type of place; after all, bicycles and long-tail boats are the only alternatives to walking.
