Arriving in Phnom Penh for the first time can be disorienting in the best possible way. The Cambodian capital is louder, messier, and more complex than the polished capitals of Singapore or Bangkok, and it demands a different kind of engagement. The tuk-tuks materialise the moment you exit the airport. The Mekong is broader than you imagined. The city's traumatic recent history sits alongside vivid street food and genuinely warm hospitality in ways that take a day or two to process. But first-timers who arrive prepared — with the right visa, the right SIM card, a clear sense of where to stay, and an honest understanding of the cultural norms — will find Phnom Penh one of the most rewarding cities in Southeast Asia. This guide covers everything before and after you land.
Before You Arrive
The most important pre-trip task is your visa. Cambodia offers an e-visa through the official government portal at evisa.gov.kh. The fee is $36 USD, processing takes 3–5 business days, and the visa is valid for 30 days single entry. Print the approval letter — some land border posts require a paper copy despite the electronic system. Do not use any third-party website charging $50–100 for the same service; they are simply resellers of the same government e-visa with an added markup.
Alternatively, a visa on arrival is available at Phnom Penh International Airport for $35 (tourist) or $35 (business). You'll need a passport photo and USD cash — the process takes 20–40 minutes at the immigration counters. This is convenient if you didn't arrange a visa in advance, but the queue at busy arrival times can be substantial.
Citizens of ASEAN countries, plus several others including Japan, South Korea, and Russia, can enter Cambodia visa-free for 14–30 days depending on nationality. Check the latest requirements at the Cambodian Ministry of Foreign Affairs website before your trip, as the list changes periodically.
Currency: Cambodia uses a dual-currency system. The official currency is the Cambodian Riel (KHR), but the US Dollar (USD) is used for almost all transactions above $1. Prices at hotels, restaurants, tour operators, and attractions are quoted in USD. Riel is used for change — the rate is fixed at 4,000 KHR per dollar in most everyday transactions. Bring USD from home (small bills: $1, $5, $20) or withdraw from ATMs on arrival. Do not convert to KHR before arriving — there is no advantage and it creates confusion.
SIM card: The two best networks are Smart (Axiata) and Metfone. Both sell tourist SIM cards at the airport for $2–5 with 5–10 GB of data included. Smart has the best 4G coverage in Phnom Penh and along main highways. Top-ups are available at every convenience store and market. Monthly data plans (15–30 GB) cost $3–8 and work better for stays over a week.
Health precautions: No vaccinations are legally required to enter Cambodia, but Hepatitis A, Typhoid, and Tetanus are commonly recommended. Dengue fever is present year-round; use mosquito repellent (DEET-based). Tap water is not safe to drink — buy bottled water or use a filtered bottle. Pharmacies in Phnom Penh are well-stocked for standard medications.
Getting from the Airport
Phnom Penh International Airport (IATA: PNH) is 10 km west of central Phnom Penh — about 20–35 minutes by road depending on traffic. The airport is compact and straightforward. After clearing immigration and collecting luggage, you'll exit into the arrivals hall where transport options are immediately visible.
PassApp taxi or tuk-tuk (recommended): Open the PassApp ride-hailing app (Cambodia's dominant equivalent of Grab) before leaving the terminal. A PassApp car to the Riverside or BKK1 area costs $7–10; a tuk-tuk costs $5–7. Fares are fixed in the app before you request — no negotiation required. This is the safest, most transparent option for first-timers unfamiliar with local prices.
Official taxi counter: Inside the arrivals hall, an official taxi desk operates fixed-rate metered taxis. The fare to central Phnom Penh is $12–15. Slightly more expensive than PassApp but reliable, with air conditioning guaranteed.
Street-hail tuk-tuk: Drivers will approach you the moment you exit the terminal. Expect to be quoted $8–12 for a tuk-tuk to the city centre; the genuine going rate for the trip is $5–7. If you negotiate, $6–7 is a fair fare to accept. Always agree on the price before getting in.
No metered meters, no buses: Unlike Bangkok or Kuala Lumpur, there is no public bus service from Phnom Penh Airport to the city, and standard metered taxis are not the norm here. PassApp or the official counter are the two cleanest options.
The journey into the city passes through the western suburbs and crosses into the BKK1 district before reaching the Mekong riverside — the route itself gives a useful first impression of the city's density and chaos.
Getting Around the City
Phnom Penh lacks a metro, tram system, or reliable city bus network. Transport is dominated by three options: tuk-tuks (open three-wheeled carriages pulled by a motorbike), ride-hailing apps, and rental bicycles. Each has its place depending on time of day, weather, and destination.
PassApp is non-negotiable for first-timers. The app offers tuk-tuks ($2–4 for most central trips), cars ($3–6), and motorbike taxis ($1.50–3). All fares are shown upfront. Driver ratings, live GPS tracking, and cashless payment make it dramatically safer and more transparent than street-hailing. Rival app Grab also operates in Phnom Penh with comparable pricing.
Street-hail tuk-tuks are everywhere and fine once you have a sense of the correct price. For most trips within central Phnom Penh — Riverside to BKK1, Royal Palace to Central Market, BKK1 to Tuol Sleng — $2–4 is the right fare. Drivers outside tourist sites, hotels, and the airport quote higher starting prices; walk slightly away from obvious pickup zones for better opening bids.
Bicycles from guesthouses or rental shops near the riverfront cost $3–5 per day. The area within 2–3 km of Sisowath Quay is navigable by bike: the riverside road, the French quarter, and the neighbourhood around the National Museum are all comfortable cycling territory. Beyond this, traffic density makes cycling stressful.
Walking is realistic only within very specific small areas — the riverside promenade itself, the BKK1 café district, or the blocks around the Royal Palace. Cross-city walking in Phnom Penh's heat (typically 30–36°C year-round) is not advised.
Where to Base Yourself
Phnom Penh's geography is more spread out than Siem Reap or Vientiane. The three most practical neighbourhoods for first-time visitors each offer a distinct experience.
Sisowath Quay (Riverside): The stretch of riverfront boulevard running north–south along the Mekong is Phnom Penh's most atmospheric address. Restaurants, bars, and guesthouses face the water, and the promenade fills with locals and tourists at dusk. The Riverside location puts you within walking distance of the National Museum, the Royal Palace, and the Wat Phnom temple. It is also the most tourist-saturated area, with predictably tourist-priced restaurants. Budget guesthouses start at $15–22 per night; mid-range hotels run $40–80. Noise from the bars carries until late on weekends.
BKK1 (Boeng Keng Kang 1): The expat heartland, roughly 2 km south of the riverfront. BKK1's grid of tree-lined streets houses the city's best cafes, international restaurants, rooftop bars, co-working spaces, and boutique guesthouses. It is quieter than the riverside, significantly cleaner, and more comfortable — the neighbourhood is built for long-stay residents rather than passing tourists. Mad Monkey hostel and Okay Guesthouse (both on Street 302 and 258 respectively) are the standout budget options. First-timers who want comfort and good food over pure location choose BKK1 as their base.
Daun Penh (French Quarter): The area around Street 240 and Norodom Boulevard, radiating from the Independence Monument, preserves the most intact French-colonial architecture in the city. Wide tree-lined boulevards, faded yellow colonial buildings, and a calmer pace make this the most photogenic base. Fewer hostels here; the accommodation skews toward boutique hotels ($45–90) and serviced apartments. Centrally located between the riverfront and BKK1, Daun Penh suits first-timers with a moderate budget who want the aesthetic reward of colonial-era streets.
Local Culture & Etiquette
Cambodia is a predominantly Theravada Buddhist country and the cultural norms around temples, greetings, and public behaviour reflect that tradition. Violations are rarely met with hostility — Cambodians are notably patient with tourists — but observing the basics signals respect that is genuinely appreciated.
Temple dress: At the Royal Palace, Silver Pagoda, Wat Phnom, and any active temple, covered shoulders and knees are required for both men and women. Sarongs and shawls are available to rent at major sites for $1 or free. Tank tops and shorts alone will get you turned away at the palace entrance — carry a light scarf or long skirt in your bag on any day you plan temple visits.
The Sampeah greeting: The traditional Cambodian greeting is the sampeah — hands pressed together at chest level in a prayer-like gesture with a slight bow. You won't offend anyone by extending a handshake instead (Western norms are understood), but using the sampeah when greeted with one shows cultural awareness and is always met warmly.
Removing shoes: At temples, many guesthouses, and some local restaurants, shoes are removed before entering. Watch what locals do and follow their lead. If shoes are stacked outside an entrance, remove yours.
Tipping: Not culturally mandatory but appreciated and increasingly expected in tourist-facing businesses. $1–2 on a restaurant meal is standard. Tuk-tuk drivers: round up to the nearest dollar. Hotel staff: $1–2 per day is customary. Massage therapists: $2–3 on a $10–15 massage. Never tip in KHR — always USD.
Photography at genocide sites: Tuol Sleng and Choeung Ek permit photography in most areas but expect visitors to conduct themselves with visible solemnity. Selfies in front of victim photographs or inside the former torture chambers are considered deeply disrespectful by Cambodian staff and fellow visitors alike. Photograph landscapes, memorials, and artefacts with a measured approach.
Bargaining: Normal and expected at markets (Central Market, Russian Market, BKK Market) but not in restaurants, guesthouses with posted prices, or modern shops. Open at 60–70% of the asking price and expect to settle at 70–80%. Never bargain aggressively or walk away angrily over small amounts.
Common Mistakes to Avoid
1. Overpaying at the airport and ignoring PassApp. The single most common first-timer mistake is accepting the first tuk-tuk price offered outside the arrivals hall ($10–15) when PassApp would have done it for $5–7. Download the app before your flight and use it from the moment you land. The same applies throughout your stay.
2. Visiting the Killing Fields without the audio guide. The entry fee of $6 includes one of Southeast Asia's finest museum audio guides — a deeply personal, narrator-led experience recorded with survivor testimony. Visitors who skip it (usually because they didn't realise it was included) wander the site without context and leave confused rather than informed. Take the audio guide.
3. Assuming USD is always optimal. While USD is widely used, many small vendors, tuk-tuk drivers, and market sellers prefer KHR for transactions under $2. Having some KHR in coins and small notes prevents the awkward exchange of receiving $0.75 in mixed Riel back from a $1 transaction. Keep a working stock of KHR for small purchases.
4. Booking accommodation on Street 136 without knowing what it is. Several budget booking platforms list cheap guesthouses on Street 136 and the surrounding blocks in Phnom Penh's entertainment district without adequate description of the environment. This area is Phnom Penh's red-light strip — consistently noisy, with an atmosphere most first-timers find uncomfortable. BKK1 guesthouses at the same price point are categorically better choices.
5. Rushing the genocide sites. Tuol Sleng Museum and the Killing Fields each require 2–3 hours to absorb properly. First-timers who schedule both in a single morning, then tack on the Royal Palace and National Museum in the afternoon, leave exhausted, emotionally overloaded, and having absorbed very little. Give the genocide sites a morning or afternoon of their own. Decompress before moving on.
6. Drinking tap water. Phnom Penh's tap water is not safe for drinking. Bottled water is available everywhere for 500–1,000 KHR ($0.13–0.25 per 500ml). Buy a large 1.5-litre bottle each morning and refill from it through the day. Some guesthouses provide filtered water for free — always ask before paying for bottled.
7. Ignoring the heat when planning walking itineraries. Phnom Penh sits at 11° north latitude and temperatures range from 30–38°C year-round. First-timers accustomed to temperate climates routinely underestimate the impact of extended outdoor walking between 11 AM and 3 PM. Schedule outdoor activities for before 10 AM and after 4 PM; use tuk-tuks for midday movement and plan a cafe stop or indoor sight during the peak heat window.
