International travel: 6 little-known mistakes that can easily lead to hefty fines while traveling.

Many seemingly minor regulations at international destinations can lead to large fines or even legal trouble. Below are six common offenses, based on penalty data from various countries, ranging from nighttime swimming in Spain to carrying e-cigarettes in Thailand, that travelers should be aware of before they travel.

Spain: nighttime beach bathing, sleeping/camping on the beach, and noisy parties.

In the town of Benidorm, swimming is prohibited between midnight and 7 pm to prevent accidents, with fines ranging from $850 to $1,400. Penalties also apply to sleeping or camping on the beach. The city of Seville closely monitors party groups, especially bachelor parties, and imposes penalties for disruptive behavior, disturbing residents, or impacting the cultural atmosphere.

• Quick note: Avoid going into the sea between midnight and 7 pm; no sleeping/camping on Benidorm beach.
• Maintain public order in Seville; do not participate in activities that cause noise or disrupt local life.

Thailand and Singapore: e-cigarettes are banned, violations can result in heavy fines.

Thailand imposes severe penalties for possessing, importing, or distributing e-cigarettes. Importing or distributing can result in fines of up to 500,000 baht (approximately 410 million VND) and imprisonment for 2–5 years. Tourists caught using vapes, even in private, can face on-the-spot fines of 10,000–30,000 baht (approximately 8.2–24 million VND), confiscation of the device, and even deportation. Recent campaigns (ordered by former Prime Minister Paetongtarn Shinawatra in early 2025) have led to hundreds of arrests, over 690 in just one week in March. Citizens can report violators and receive up to 60% of the fine (for example, a 5,000 baht fine, the whistleblower receives 3,000 baht).

Similarly, Singapore has a complete ban on the import, sale, and use of e-cigarettes. First-time offenders can be fined from S$500 (approximately VND 10 million) for those under 18, up to S$700 (approximately VND 14 million) for adults. If the vape contains etomidate, the penalties are higher, potentially including up to six months in prison and mandatory rehabilitation.

• Quick note: Do not bring, buy, or use vapes in Thailand and Singapore.
• Even using it in private in Thailand can result in fines and deportation.

Italy: Strict environmental protection in Sardinia and order in Portofino.

Sardinia limits the number of tourists on popular beaches and imposes fines of nearly $4,000 for sand theft, particularly at the pink Spiaggia Rosa beach. This beach has been closed to visitors since the mid-1990s to prevent further sand loss, although some people still try to access it unaware of the ban. In the village of Portofino, loitering in popular photo spots can result in fines of around $300 to reduce pedestrian traffic congestion; the regulations apply to two “red zones” and have been in effect since Easter weekend.

• Quick note: Do not take sand, shells, or rocks in Sardinia; do not enter restricted areas such as Spiaggia Rosa.
• In Portofino, please refrain from lingering to take photos in the "red zone" as it obstructs the flow of people.

Japan: Preparing to require private travel insurance

The Japanese government is preparing to require all tourists to have private travel insurance after a surge in the number of people who used medical services and then left without paying. In September 2024 alone, over 11,000 tourists received hospital treatment, and nearly 90 left without paying. With a target of 60 million tourists annually by 2030, Japan is adjusting its policy to ensure the system's sustainability. The insurance requirement could be checked at customs, potentially causing entry delays for those who are not prepared.

• Quick note: Be sure to have your private travel insurance certificate ready when traveling to Japan.

Portugal: Mobile speakers banned on beaches.

Portugal imposes hefty fines for loud noise on beaches. The National Maritime Authority bans portable loudspeakers; fines range from approximately $200 to $39,000 for individuals and groups, aiming to maintain a peaceful experience for everyone. The regulation reflects an effort to balance tourism revenue with the quality of life for residents as beach parties and loud music systems become more prevalent.

• Quick note: No loud speakers/sound systems on the beach; please maintain order and respect public space.

New Zealand: NZeTA/visa required, including transit.

From October 1, 2019, all visitors to New Zealand must have a valid visa or NZeTA (for passport holders eligible for visa exemption and Australian Permanent Residents). NZeTA approval can take up to 72 hours. This requirement applies even to transit passengers, even if they do not leave the airport. Border authorities are increasing checks; undeclared items may be confiscated, so it is advisable to declare them during the electronic application process.

• Quick note: Submit the NZeTA at least 72 hours before your trip; check transit requirements; declare goods in electronic documents.
