Packing for Siem Reap is a puzzle with two constraints that pull against each other: the temples enforce a modest dress code, and the climate wants you in as little as possible. Get the balance right and every day runs smoothly; get it wrong and you're buying elephant-print trousers from a vendor at the Angkor Wat gate at 6am. Here's the list that solves it.
The Golden Rule: Cover Shoulders and Knees
Everything you pack for temple days has to clear one bar — shoulders and knees covered, enforced strictly at the upper levels (the Bakan of Angkor Wat and the Phnom Bakheng summit). This isn't a suggestion at those spots; you'll be turned away. The trick is covering up in fabrics that breathe, which is the whole art of dressing for Angkor. Our full dress code guide has the specifics; here's what to actually pack.
Clothing
- Loose, lightweight long trousers (linen, or technical quick-dry) — cooler in direct sun than you'd expect, and they pass every check. Two pairs.
- T-shirts with real sleeves — short sleeves are safe; skip the tanks and strappy tops for temple days. Merino or technical tees dry fast when you sweat through them, which you will.
- A light long-sleeve overshirt — doubles as sun protection at 10am and a layer for the genuinely cool pre-dawn if you're doing sunrise in the November–February season.
- A scarf or light sarong — versatile: extra coverage, sun shade, something to sit on. Note a draped scarf does not substitute for sleeves at the enforced upper levels.
- Comfortable closed shoes — the temples involve real climbing on steep, uneven stone. Trainers or sturdy sandals with grip; not flip-flops for the Bakan stairs.
- Evening clothes — town is relaxed. Pub Street is shorts-and-tee territory; only the fine-dining rooms warrant something smarter, and even then "smart casual" is plenty.
- Swimwear — nearly every hotel has a pool, and after a temple morning it's the entire point. Also for the Kulen waterfall.
Pack for Your Season
The month changes the list more than people expect (full breakdown in our best-time guide):
- Cool & dry (Nov–Feb): add that overshirt or a light layer — pre-dawn at the temples is genuinely cool, even if midday isn't.
- Hot season (Mar–May): maximum breathability, a real sun hat, and double the electrolyte plan. The stone radiates heat.
- Green season (Jun–Oct): a packable rain shell or cheap poncho and quick-dry everything. Tuk-tuks have roll-down sides, but you'll get caught out; it's part of the fun.
The Small Things That Matter Most
- Sunscreen and a hat — the shade-free hours are brutal year-round; this is the real adversary of a temple day, not the dress code.
- A refillable water bottle — tap water isn't potable, but hotels and many sites offer refills, and dehydration is the number-one way people ruin an afternoon.
- Bug spray — essential for the pre-dawn wait by the Angkor Wat reflection pool, where the mosquitoes hold their own sunrise gathering.
- A power bank — long temple days drain phones you're using as camera, map, and pass backup.
- Crisp small-denomination US dollars — USD is the currency you'll spend; torn or scruffy bills are often refused, and a fresh $100 is hard to break at a noodle stall. ATMs dispense USD; riel comes back as small change. More in the budget guide.
- A daypack — for water, layers, sunscreen, and the scarf, worn on the front in crowds.
- Basic meds — rehydration salts, any stomach settler you trust, and plasters for temple-stair scrapes.
What You Can Skip
- A drone — effectively banned over the Angkor park without a hard-to-get permit. Leave it home.
- A heavy tripod — you'll be hand-holding in a sunrise crowd anyway (the photography guide explains).
- Formal wear — nowhere in Siem Reap requires it.
- Too many clothes — laundry is cheap and fast, and you'll want backpack room for Artisans Angkor silk and Kampot pepper on the way out.
Don't Forget the Paperwork
Your packing list starts before clothes: passport valid six months out, your tourist visa, and the free e-Arrival card — all covered in the Cambodia visa guide. And the temples need a separate Angkor Pass, not included in any tour price.
One Thing to Sort Before You Zip the Bag
The single highest-value pre-trip booking is the sunrise tour — it sells out in peak season and handles the 4:30am logistics so your only job is to have packed the right layer the night before:
