Quick answer

Pack for St. Thomas with reef-safe mineral sunscreen (sunscreens with oxybenzone, octinoxate, or octocrylene are banned in the USVI since March 30, 2020), lightweight beach clothing, a swimsuit and rash guard, water shoes for snorkel-spot rocky entries, sturdy walking shoes for Charlotte Amalie's steep streets, modest cover-ups for restaurants, and packable rain gear for May-November. No passport, visa, currency exchange, power adapter, or international phone plan needed for US travelers (USVI is a US territory). Drive on the LEFT despite right-hand-drive cars. Travel insurance with hurricane coverage strongly recommended September-October.

US Virgin Islands (US Territory)

Packing for St. Thomas means packing for a Caribbean destination that is also a US territory, which simplifies almost every logistical concern. No passport, no visa, no currency exchange (USD is the official currency), no SIM card swap (US carrier plans work natively), and no power adapter (Type A/B at 110V/60Hz). The climate is the variable: hot humid tropics with a dry season (December-April) and wet season (May-November), including a serious hurricane risk that hit hard with Irma and Maria in 2017.

St. Thomas has two main visitor areas. Charlotte Amalie (the capital) is the cruise port and shopping district with hundreds of duty-free jewelry, watch, and liquor shops. The East End (Red Hook) has the ferries to St. John (8 km away) and the most popular beach hotels. Magens Bay on the north shore is the famous swimming beach (often ranked top-10 in the world). The island is small (32 sq mi) but the terrain is mountainous with narrow winding roads; driving requires real attention, particularly because they drive on the LEFT (despite being a US territory and using right-hand-drive American cars).

Since March 30, 2020, USVI law has banned selling, importing for sale, and using or possessing sunscreen that contains oxybenzone, octinoxate, or octocrylene. The ban covers the whole territory, not just the beaches, so it applies at Magens Bay, Coki Beach, and on St. John alike. Bring at least one full bottle of mineral SPF (zinc oxide or titanium dioxide) from home; gift shops mark up 3-4x.

Packing Tips for St. Thomas, US Virgin Islands

  1. 1The US Virgin Islands are a US territory. US citizens do not need a passport, visa, or international phone plan. Domestic US flight rules apply. USD is the official currency.
  2. 2Power outlets are US-style Type A and Type B at 110V/60Hz. No adapter needed for US/Canadian travelers. European, UK, and Australian travelers need a US-style adapter.
  3. 3Sunscreen containing oxybenzone, octinoxate, or octocrylene has been banned across the USVI since March 30, 2020, including using or possessing it. A mineral SPF (zinc oxide or titanium dioxide) is the simple way to comply. Bring at least one full bottle from home; gift shop prices are 3-4x mainland.
  4. 4Drive on the LEFT in the US Virgin Islands. This is unique among US territories. Despite right-hand-drive American cars, all driving is left-side. Narrow mountain roads and frequent stop signs make rentals tricky for first-time visitors; many travelers use taxis.
  5. 5Charlotte Amalie's steep stair-streets (Spanish 99 steps) and historic district require sturdy walking shoes with grip. The downtown is built on hillsides; sneakers work, heels do not.
  6. 6St. John is reached via Red Hook ferry (20 minutes, multiple daily trips) or the Charlotte Amalie ferry (less frequent). Two-thirds of St. John is US national park; pack hiking shoes if planning to explore Virgin Islands National Park.
  7. 7Tipping follows US norms (USVI is a US territory): 18-20 percent at restaurants, $1-2 per drink at bars, $2-5 per day for housekeeping, $10-20 per dive tank.
  8. 8Hurricane season runs June through November with peak risk September-October. Travel insurance with hurricane and trip-interruption coverage is strongly recommended for fall trips. Hurricanes Irma and Maria (September 2017) caused catastrophic damage; the island has substantially recovered but verify your specific resort and ferry operating status before booking.

Frequently asked questions

Do I need a passport for St. Thomas?
No. The US Virgin Islands are a US territory, and US citizens travel there on domestic flight rules. A government-issued photo ID (driver's license, REAL ID, or passport) is sufficient for TSA. Non-US citizens follow US visa rules for arrival to the United States. No customs declaration applies (USVI is part of the US Customs Zone).
Is reef-safe sunscreen required in St. Thomas?
Yes, effectively: since March 30, 2020, USVI law has banned selling, importing for sale, and using or possessing sunscreen that contains oxybenzone, octinoxate, or octocrylene. The ban is territory-wide, not limited to beaches or the national park, and fines run $1,000 for a first offense. The law names chemicals rather than requiring mineral sunscreen, but a mineral SPF with zinc oxide or titanium dioxide is the easy way to stay clear of all three. Bring at least one full bottle from home; gift shop prices in Charlotte Amalie and at resorts are 3-4x mainland.
Do I drive on the left or right in the US Virgin Islands?
LEFT. This is the only US territory or state where driving is on the left side of the road. The cars are still right-hand-drive American imports though, which makes the experience strange for first-time visitors (you sit on the left side of the car as in mainland US, but the driving lane is on the left). Narrow mountain roads and frequent stop signs make rentals tricky; many travelers use taxis or hotel shuttles. If renting, book in advance for the airport pickup.
Do I need a power adapter for St. Thomas?
Not if you are from the US or Canada. The US Virgin Islands use US-style Type A and Type B outlets at 110V/60Hz, essentially identical to US mainland household power (mainland is technically 120V but the small difference is irrelevant for all consumer electronics). European, UK, and Australian travelers need a US-style adapter.
What should I pack for a St. John day trip?
St. John is two-thirds Virgin Islands National Park. Pack hiking shoes (the trails to Trunk Bay, Cinnamon Bay, and Reef Bay are well-marked but rocky), a swimsuit and quick-dry beach towel, reef-safe sunscreen SPF 50+ (the USVI sunscreen ban applies on St. John too), strong insect repellent, a refillable water bottle (no water stations on trails; pack 1L+ per person), a dry bag for ferry crossings, and US currency for the small St. John shops. The Red Hook ferry runs about every hour (20-minute crossing, $8.55 each way); the Charlotte Amalie ferry runs less frequently.
What should I pack for hurricane season in St. Thomas?
Pack a quick-dry rain jacket, quick-drying sandals, an extra phone charger and power bank (power outages possible during storms; St. Thomas's grid is more vulnerable than mainland US), strong insect repellent, and travel insurance with named-storm and trip-interruption coverage (especially for September-October). Hurricanes Irma and Maria (September 2017) caused catastrophic damage; the island has substantially recovered but verify your specific resort and ferry operating status before booking. Flight cancellations and damage to specific properties remain real risks.
Is tap water safe in St. Thomas?
Technically yes; US federal water safety standards apply. But local infrastructure has been more inconsistent since the 2017 hurricanes, especially in older buildings. Most travelers stick to bottled or filtered water for taste preference and reliability. Resort all-inclusives provide filtered water. Bottled water is widely sold at supermarkets and convenience stores.
How much should I tip in St. Thomas?
Tipping follows US norms (USVI is a US territory). Restaurants: 18-20 percent if not included (some resort restaurants add automatic service charges; check the bill). Bartenders: $1-2 USD per drink. Hotel housekeeping: $2-5 USD per day. Taxi drivers: 15-20 percent (taxis are not metered; agree on a price before getting in or use the official VI Taxi Association fares). Dive masters: $10-20 USD per tank. Tour guides: 15-20 percent.
