City overview
Siem Reap is the Cambodian base for Angkor Archaeological Park, with the Siem Reap River, Old Market, Pub Street, Wat Bo, and Kandal Village forming the city map after temple hours. The city itself adds Khmer performance, Angkor National Museum, craft workshops, and Tonle Sap village access, so a good route alternates Angkor mornings with Old Market, Wat Bo, and river evenings.
Food & drink
Siem Reap food is gentler than Thai spice but still specific: fish amok is a coconut-curry custard often steamed in banana leaves, bai sach chrouk is grilled pork over rice, and num banh chok is rice noodles with herb-rich fish gravy. Old Market stalls, Wat Bo Road restaurants, Pub Street kitchens, Road 60 vendors, and Sombai workshops add beef lok lak, kuy teav, Khmer curry, palm-sugar sweets, and green mango salad.

Neighborhoods
1Old Market and Pub Street
This is the busiest visitor core, with Psar Chaa, Pub Street, night-market lanes, bars, souvenir stalls, and tuk-tuk queues beside the river.
2Wat Bo Village
Wat Bo is calmer and restaurant-heavy, with the pagoda, small hotels, cafes, guesthouses, and local streets east of the Siem Reap River.
3Kandal Village
Kandal Village is compact and design-minded, with coffee shops, boutiques, Common Grounds, galleries, and walkable lanes north of the Old Market.
4Taphul Road
Taphul Road is practical and guesthouse-oriented, with budget hotels, laundries, travel desks, small restaurants, and easy airport-road access.
5Sok San Road
Sok San Road runs west from the Old Market area, mixing hostels, massage shops, bars, street food, and late-night movement.
6Charles de Gaulle and Royal Gardens
The Angkor approach road has larger hotels, Angkor National Museum, Royal Gardens, and a quieter route toward the temple checkpoints.
Day trips
37km / 50-60min by tuk-tuk or car from Old Market
Banteay Srei
The pink-sandstone temple has unusually detailed carvings and works best as a morning extension from the Angkor pass route.
30km / 45min by car plus boat from central Siem Reap
Kampong Phluk and Tonle Sap
The stilt village and flooded forest show Tonle Sap seasonal water levels, with the most dramatic lake scenery during high water.
50km / 1.5-2h by car from Siem Reap
Phnom Kulen
The mountain has waterfalls, riverbed carvings, temples, and picnic areas tied to Khmer history outside the main Angkor complex.
Getting around
Tuk-tuks, remorks, taxis, bicycles, and hotel cars handle most movement, with temple circuits usually priced by small loop, grand loop, or day rate. Buy the Angkor pass before temple touring and group Old Market-Wat Bo-Kandal Village on foot after dark.
