About Tonga

From steep, active volcanoes, to low coral atolls, Tonga's 170 islands offer a truly diverse array of backdrops for those seeking a Pacific getaway.

Tonga enjoys a laidback pace of life which visitors find easy to adopt, whether relaxing on one of the magnificent white sand beaches, first-class diving amid the stunning coral reefs or watching the migratory whales return to their breeding grounds (June to November). Many of the islands are uninhabited, and have much emerald flora and secluded coves to explore.

Sightseeing highlights include the Royal Palace on the waterfront in Nuku'alofa, the Mala'ekula (Royal Tombs), and the Anahulu Cave: an underground cavern of stalactites and stalagmites. Tonga is ruled by the last remaining Kingdom of Polynesia. The ruling family of Tonga, the last remaining Polynesian Kingdom, can be traced back more than 1,000 years.

  • an onward or return ticket

There is a high threat of terrorist attack globally affecting UK interests and British nationals, including from groups and individuals who view the UK and British nationals as targets. Stay aware of your surroundings at all times.      

UK Counter Terrorism Policing has information and advice on staying safe abroad and what to do in the event of a terrorist attack. Find out how to reduce your risk from terrorism while abroad

Terrorism in Tonga 

Although there’s no recent history of terrorism in Tonga, attacks cannot be ruled out. 


Protecting yourself and your belongings 

The level of serious crime is low, but petty theft is fairly common. To protect yourself and your property: 

  • do not leave bags unattended 
  • use hotel safes or deposit boxes for passports and valuables 
  • stay in well-lit and populated areas after dark 
  • keep villas and hotel rooms locked and secure 

Laws and cultural differences  

Customs and dress code 

Tongan society is very conservative and highly religious. People strictly observe the Sabbath. On Sundays, local people may consider recreational activities to be disrespectful. This does not apply to island resorts.  

Topless sunbathing and nudity in public is illegal. You could be fined up to 100 pa’angas or get a prison sentence of up to 4 months if you refuse to pay.  

Swimwear is acceptable on the beach or by streams and waterfalls, but in other areas it is likely to receive negative attention. 

Mobile phone coverage 

You can buy a local SIM card at the airport. You register it by giving your personal ID. Network coverage is usually reliable in towns, but can be patchy in rural locations.   

Alcohol laws and bans 

It’s illegal to drink alcohol in public except at bars or restaurants. The legal drinking age is 21. It is illegal for anyone aged 20 or under to buy alcohol. Drunken behaviour is likely to receive negative attention from locals. 

Illegal drugs and prison sentences 

Drug taking in all forms is illegal. The maximum penalty for importing or exporting illegal drugs is 30 years’ hard labour and fines of several hundred thousand US dollars. If you are found guilty of cultivating or distributing illegal drugs, you are likely to receive a severe punishment. 

LGBT+ travellers 

Same-sex sexual activity between men is illegal in Tonga and the law is occasionally enforced. Same-sex partners showing affection in public may receive negative attention.

Outdoor activities and adventure tourism  

Swimming and surfing safety 

Take local advice before swimming or surfing. Tonga’s tides can produce powerful currents in ocean lagoons. There have been fatal accidents on popular beaches.  

Many waves break directly on to reefs. The sea and beaches may have loose rocks and other debris resulting from the underwater eruption of the Hunga Tonga-Hunga Ha’apai volcano. Take extra care when swimming. 

For more advice, see water safety on holiday from the Royal Life Saving Society. 

Scuba diving 

Before scuba diving, check you are covered by your insurance. You should also: 

  • ask for the dive operator’s credentials 
  • make sure safety equipment and oxygen is available on the boat 
  • check for damage before using any equipment 
  • insist on training and ask operators to explain safe practices 
  • check what to do if something goes wrong, including how to call for help while at sea 

There is currently no hyperbaric chamber on Tonga, so get advice from your dive instructor or dive team.  

Whale boats 

Thousands of whales frequent the waters of Tonga every year between June and November. There are strict regulations on whale watching. It is illegal to swim or kayak with whales unless you are on a licensed boat with a certified guide. If convicted, you could get a fine of up to 5,000 pa’angas or an 18-month prison sentence – or both. The authorities can apply these penalties to a first-time offence.  

Transport risks  

Road travel  

If you are planning to drive in Tonga, see information on driving abroad. You can drive using your UK driving licence.   

Roads are generally in good condition, but inland they can be narrow and potholed. Speed limits are low and traffic police can issue on-the-spot fines if you exceed them. All drivers and front seat passengers must wear seatbelts. It is illegal to use a mobile phone while driving.  

When driving near villages watch for children and animals on the roads. Avoid driving at night as roads are poorly lit and hazards such as livestock and pedestrians make driving very dangerous. 

Sea travel 

Safety at sea, particularly on board older vessels, is a concern in Tonga. Ferries do not follow normal safety regulations and are often overloaded. Consider carrying your own lifejacket.  

Air travel 

Severe weather can cause flight delays and cancellations. Stay in touch with your travel provider. 

Extreme weather and natural disasters 

Find out what you can do to prepare for and respond to extreme weather and natural hazards

Tropical cyclones 

The tropical cyclone season normally runs from November to April, but cyclones can happen throughout the year. Severe weather may cause floods, landslides, road closures and disrupt essential services and infrastructure. Take local advice and monitor local and international weather updates from World Meteorological Organization or Tonga Meteorological Services.  

Earthquakes and tsunamis 

Tonga is part of the Pacific Ring of Fire, a zone of frequent earthquakes and volcanic eruptions. Earthquakes and volcanic activity can happen at any time and trigger tsunamis. Check tsunami alerts for the region

The US Federal Emergency Management Agency website has advice about what to do before, during and after an earthquake or tsunami.  

Before you travel check that: 

  • your destination can provide the healthcare you may need 
  • you have appropriate travel insurance for local treatment or unexpected medical evacuation  

This is particularly important if you have a health condition or are pregnant. 

Emergency medical number 

Call 933 and ask for an ambulance. 

Contact your insurance company quickly if you’re referred to a medical facility for treatment.
