What to Pack for a Caribbean Island-Hop

Caribbean island-hopping — visiting 2–3 islands across a single trip — has specific packing demands beyond a single-destination Caribbean trip. The combination of inter-island ferries (which often have luggage size limits), small inter-island flights (with strict weight limits), the need for some variety across multiple beach destinations, and the time spent in transit between islands. The kit that handles 7–10 days of island-hopping is more deliberate than people initially expect.

The bag itself. A medium-sized soft-sided duffel or a small wheeled carry-on. Inter-island ferries often have weight or size limits; small planes (Cessnas, twin-engine commuter planes between islands) have strict weight limits — usually 30–40 lbs (15–18 kg) total. A large rolling suitcase or trunk often fails these limits. The right bag is a 35–50L soft duffel or carry-on, plus a small daypack as your personal item.

Wardrobe in light tropical colors. Five lightweight tops in light colors (white, pastel blue, beige) — they reflect heat and look right against the iconic Caribbean blue. Two pairs of lightweight bottoms (one pair of shorts, one pair of pants or a midi dress that handles both daytime and evening). One nicer outfit for restaurant evenings or hotel events — most Caribbean restaurants are casual, but specific resort restaurants have dress codes. Three swimsuits — you'll always have one drying on the line. Sleep wear.

Footwear. Three pairs total. One pair of slip-on sandals (Birkenstocks, quality leather sandals — not $5 flip-flops, which destroy themselves on rocky beaches within a few days). One pair of comfortable walking shoes for non-water activities. One pair of water shoes for rocky beach entries and snorkeling — Caribbean beaches range from white sand to coral pebble; water shoes prevent foot injuries.

Sun protection is critical. The Caribbean sun is intense year-round, especially on water. Long-sleeve UPF 50 sun shirts (one for snorkel days, one for boat days). SPF 50 reef-safe sunscreen — required by law in several Caribbean destinations including the British Virgin Islands and parts of Mexico. SPF lip balm. Wide-brimmed hat with chin strap (boat winds will take it). Polarized sunglasses with strap.

Snorkel gear. The Caribbean has world-class snorkeling, and bringing your own gear pays back. A personal mask and snorkel from Cressi or Mares ($40–80) packs into nothing and provides reliable seal across multiple destinations. Fins are optional — most resorts and dive shops rent fins, and bringing your own takes meaningful luggage space. A rash guard for serious snorkel sessions.

Tech for inter-island travel. Universal power adapter (Caribbean countries use various plug types; Type A/B for US-aligned countries, Type G for British-aligned). 10,000mAh portable charger (boat days are long; cell-tower coverage between islands varies). eSIM service (Airalo, Holafly) covers most Caribbean countries reliably. A waterproof phone pouch for boat trips and rocky beach swimming.

Documents and money. Passport with 6+ months validity. Copies of passport stored separately. Some USD cash in small denominations — many smaller Caribbean countries accept USD even though local currency exists. Two credit cards from different banks. Travel insurance details. Inter-island ferries and small-plane flights often have their own ticketing systems separate from major airlines; print confirmations for each leg.

Specific island-hop logistics. Some Caribbean countries require entry stamps and exit stamps for each island — you'll get a passport stamp at every entry and exit. Some smaller airports may not have ATMs or restaurants; bring cash and snacks for transit. Inter-island flights are often delayed; build buffer time. Ferry schedules are seasonal and weather-dependent; always confirm the day-of.

What to skip. Cotton t-shirts (heavy, slow-drying, won't survive humid evenings). Heavy coats. Heels (Caribbean nightlife is casual). Excessive resort wear if you're staying at multiple boutique properties. The over-packed Caribbean bag is universally regretted; you'll wear less than you think.
