Most nationalities can obtain a 30-day tourist visa on arrival at Dili airport or at the land border crossing, for a fee of $30 USD payable in cash. Citizens of the European Union and Schengen Area countries, along with a small number of others such as Indonesia and Cabo Verde, can enter visa-free for stays of up to 90 days under existing waiver agreements. Visas on arrival can be extended at the Immigration Department in Dili, and travelers should apply at least a week or two before their current visa expires. Anyone entering by land, apart from Indonesian, Portuguese, or American citizens, needs to arrange a Visa Application Authorization in advance through a Timor-Leste diplomatic mission.

The dry season runs roughly from May through November and is generally considered the best time to visit, with clearer roads, better diving visibility, and easier trekking conditions. The wet season, from December through April, brings heavy rain that can make mountain roads difficult or impassable and can limit access to some of the more remote regions. If whale watching is a priority, aim for the period between September and December, when migrating whales pass close to the northern coast.

Tetum and Portuguese are both official languages, with Tetum serving as the everyday lingua franca across most of the country and Portuguese used mainly in government, education, and among older generations who were educated during the colonial period. Bahasa Indonesian remains widely spoken as a legacy of the occupation years, particularly among people who came of age during that period, and English is increasingly used in tourism and business, especially among younger Timorese in Dili.

The US dollar is the official currency of Timor-Leste, with small centavo coins used alongside it for change. Very few businesses outside Dili accept credit cards, and where they do, a surcharge is common, so cash is essential for most transactions, particularly outside the capital. ATMs exist in Dili and to a lesser extent in a few other towns, but they can be unreliable, so it is wise to withdraw what you need while in the capital rather than relying on finding a working machine elsewhere.

No, there is no requirement to travel with a guide, and independent travel is common, especially around Dili. That said, a guide is highly recommended for trekking in the highlands, for diving trips, and for visiting more remote villages, both for practical reasons like language and road conditions and for the cultural access a local guide can provide.

Timor-Leste is generally considered safe for travelers, with violent crime against foreigners being rare. Normal precautions apply, such as avoiding walking alone at night in unfamiliar areas and staying aware of local political demonstrations, which occasionally occur in Dili and can turn tense even if they are not typically directed at visitors.
