The overall level of the advice has changed; we no longer advise against all but essential travel to the whole country. We advise against all travel to specific parts of Thailand. We advise against all but essential travel to other specific parts of Thailand, including Bangkok.
- We advise against all but essential travel to Bangkok, in view of the continued political unrest in the city.
- You should exercise caution, especially in the northern provinces and Pattaya. The political situation is unpredictable and throughout Thailand there is a continued risk that protests may result in violent disturbances. Travellers are advised to avoid political demonstrations and large gatherings.
- We advise against all travel to the Preah Vihear (Khaoi Pra Viharn in Thai) temple area, due to violence in the area. See the Local Travel section of this Travel Advice.
- We advise against all but essential travel to, or through, the far southern provinces of Pattani, Yala, Narathiwat and Songkhla, due to the insurgency in these areas. See the Terrorism / Security section of this Travel Advice.
- A large number of anti-government ("Red Shirt") protestors are based at the Ratchaprasong intersection on Sukhumvit Road in central Bangkok. Many shops and businesses in the area are closed and there is severe traffic disruption at the rally site and surrounding area. Groups opposed to the Red Shirts have held counter-demonstrations close to the Red Shirt protest area. There have been several instances of violent clashes between groups of protestors. On 21 April, one foreign tourist was injured during a confrontation between protest groups in Bangkok.
