History

Angkor

LBM1948 · CC BY-SA 4.0

Go for the bas-reliefs at Angkor Wat, the face towers of Bayon and Ta Prohm's masonry gripped by roots. More than a single monument, it lets you walk through the remains of a whole medieval capital.

Tip: Start before sunrise and give it two mornings if you can; the main temples are better spread out than rushed.

    City

    Phnom Penh

    The capital puts the Royal Palace, the National Museum and Tuol Sleng in one compact day, then sends you to the riverfront for dusk. It is where court ritual, French-era streets and the violence of the 1970s sit uncomfortably close.

    Tip: Stay at least two nights; do Tuol Sleng early, then keep the Mekong and Tonlé Sap waterfront for evening.

    Culture

    Battambang

    Come for market breakfasts, low-rise streets that still move at bicycle pace and the bat exodus from nearby Phnom Sampov at dusk. It gives you western Cambodia without the temple crowds.

    Tip: Stay the night; head to Phnom Sampov before dusk and wait for the bats rather than turning up at dark.

  • Kep, Cambodia, Cambodia

    Kep, Cambodia

    Lunch is the point: crab cooked with green Kampot pepper, eaten within sight of the boats that landed it. Between meals you can walk past decaying villas and up into Kep National Park.

    Tip: Come for lunch rather than a resort stay; the Crab Market is busiest late morning.

  • Adventure

    Cardamom Mountains

    This is the other Cambodia: rainforest, river crossings, leeches, hornbills and community-run camps deep in the southwest. After stone and cities, it puts the country back in the scale of forest.

    Tip: Go with a lodge or licensed guide, especially in the rains, and pack a dry bag.

Eat

What to eat in Cambodia

  • Bai sach chrouk

    Thin slices of pork marinated with garlic and coconut milk are grilled over charcoal and served over rice with pickles and a light broth.

    Where: At dawn street stalls and corner breakfast shops; this is a morning meal.

  • Num banhchok — Cambodia

    Num banhchok

    Fresh rice noodles are topped with a light fish gravy scented with lemongrass, turmeric and kaffir lime, then covered with raw leaves and vegetables.

    Where: From morning market sellers and women carrying baskets through neighbourhoods.

  • Fish amok — Cambodia

    Fish amok

    Fish is mixed with kroeung curry paste, coconut milk and egg, then steamed, often in a banana-leaf cup.

    Where: At neighbourhood rice restaurants and on family celebration tables; it is better there than on buffet lines.

  • Kdam chaa

    Crab is stir-fried with fresh green peppercorns, garlic and sauce, then cracked open at the table.

    Where: At the Crab Market in Kep, with the sea a few steps away.

Story

The story, in three chapters

Before sunrise in Siem Reap, the air smells of incense, damp stone and grilled pork, and the road to Angkor is already full of scooters. Later, in Phnom Penh, you can walk from the Royal Palace to Tuol Sleng and feel the century tilt under your feet. What stays with people is the rhythm: shoes off at the doorway, iced coffee before the heat, and wedding music drifting out of a tented side street after dark.

  1. Chapter 1

    Stone and water

    In 802, a court ritual on Phnom Kulen marked Jayavarman II as a king apart. Engineers then cut canals and reservoirs into the plain and turned monsoon water into rice. In the early twelfth century, Suryavarman II ordered Angkor Wat, its galleries filling with battles, gods and the churning sea of Hindu myth. When Cham forces reached Angkor in 1177 by water, Jayavarman VII answered with a new capital and the stone faces of Bayon.

  2. Chapter 2

    The city emptied

    On 17 April 1975, Khmer Rouge troops entered Phnom Penh to cheers, dust and black smoke. Within hours they were pushing patients out of hospitals, families out of shopfronts and whole streets onto the roads. At Tuol Sleng, schoolrooms became cells and mug-shot rooms. Vietnamese forces took the capital in January 1979, but the country that reopened after that was not the one that had been emptied.

  3. Chapter 3

    After the blue helmets

    In 1993, blue-helmeted UN staff and voters lined up at schools and pagodas for a national election. Angkor returned to world itineraries, garment factories pulled young workers into the city and Siem Reap filled with hotels and tuk-tuks. Power stayed tight: Hun Sen ruled for decades before handing the premiership to Hun Manet in 2023. At dawn now, monks still collect alms beside iced-coffee carts and delivery bikes.

Say hello

    A polite hello

    Say: joom reap suor

  • អរគុណច្រើន

    Thanks a lot

    Say: aw-kun chrahn

  • អត់អីទេ

    No worries / it's fine

    Say: ot ey tay

  • ញ៉ាំបាយហើយឬនៅ?

    "Eaten yet?" — often just a warm way of asking how you are

    Say: nyam bai hoy rue nov?

Surprises

Things you did not know

  1. In 2022, scientists in Stung Treng documented a giant freshwater stingray from the Mekong as the heaviest freshwater fish ever recorded. The river here still produces creatures that sound like travellers' tales.

  2. Cambodia chose one of the world's rarest large birds as its national bird. The giant ibis still survives in the northern dry forests, where conservation work now protects nests and seasonal feeding pools.

  3. Kampot pepper has the same kind of European legal protection as Champagne. The EU granted it protected geographical indication status in 2016, tying the name to pepper grown in a defined area around Kampot and Kep.

Cambodia: know before you go

Best time to go
November to February for drier air and easier road travel; June to August if you want green fields and can live with afternoon rain.
Budget
LowStreet food and simple rooms are cheap by world standards, but temple passes, private cars and lodges in remote areas lift the cost quickly.
Etiquette
Dress modestly for pagodas and active shrines, and take your shoes off when asked. Using both hands to give or receive something from an elder or at a shrine is a small courtesy that reads well.
Safety
The everyday risks are traffic and phone or bag snatches in the cities. Keep your phone away from the street edge, use ride apps or arranged drivers at night, and do not wander off marked paths in remote countryside because unexploded ordnance still exists.
