What to know before you go to Tonga
The single thing worth knowing first: Polynesian kingdom. Drug penalties strict. Same-sex relations criminalized but rarely enforced. Topless sunbathing is illegal. Conservative dress in villages. Dry on Sundays in many places (no commerce). It is the kind of rule that looks minor at home and becomes a serious problem at the border or in public, which is exactly why it tops this page.
Within everyday activities and public behavior, Tonga treats Sunday commerce / sport, Topless sunbathing, and Photography in villages without permission as off-limits. Carrying or doing any of these can mean confiscation, fines, or detention depending on the case — and a foreign prescription, habit, or "I didn't know" rarely helps once you are stopped. Each entry below links to the official source it is checked against, with the verified ones marked.
Two things travelers regularly get wrong about Tonga: Topless sunbathing is illegal even on resort beaches — Tonga is more conservative than most of Polynesia; and Sunday flights still operate but most ground commerce stops. Assumptions like these are how otherwise careful visitors end up in trouble, so it is worth checking the specifics rather than guessing.
One important caveat: Sunday Sabbath is constitutionally protected — most shops closed, sports restricted, swimming OK on resort beaches but not in town. Laws and their enforcement can shift between regions and over time, so treat this page as a sourced starting point and confirm anything borderline against the official links before you rely on it.
