Packing for Phuket differs a little from packing for an inland city like Bangkok — the focus here is on beach conditions, high humidity, and water activities, while still keeping modesty in mind for temple visits.

What to pack: Modest swimwear is essential, of course, but also pack a light long-sleeved shirt or rash guard for sun protection during water activities, since Phuket's tropical sun is far stronger than it feels thanks to the refreshing sea breeze. For daily wandering, choose loose, light clothing that copes with high humidity, plus a light shawl or cover you can use when visiting Wat Chalong or any other active temple requiring shoulders and knees to be covered. Bring lightweight water shoes if you're planning boat trips or walking on coral reef rocks — they protect against cuts and give better grip than regular sandals. Don't forget high-protection, waterproof sunscreen — arguably the single most important item in your bag after clothing.

How much to budget: Beyond hotel and flights, budget roughly an extra $300–450, covering at least one Phi Phi Islands boat trip ($45–110 per person), meals, and perhaps an ethical elephant experience or a beach massage. Phuket runs slightly pricier than inland Thai cities due to its coastal tourism nature, so allow roughly 15–20% more margin compared to a Bangkok budget.

Phuket-specific savings tips: Book boat trips directly with tour operators rather than through hotel desks, where commissions tend to be higher, and compare prices across several agents before booking a Phi Phi trip specifically, since differences can be significant between companies for essentially the same itinerary. Avoid buying drinks and snacks directly from beachside stalls if prices look clearly inflated, and instead find the nearest 7-Eleven, where prices are fixed and reasonable.

A final seasonal tip: In the dry season (November–April) you won't need any extra rain protection, but during the rainy season (May–October) pack a light, foldable raincoat — the showers are usually brief but heavy and don't need to cancel your whole beach day.
