Siem Reap is the second-largest city in Cambodia and the capital of Siem Reap Province in northwestern Cambodia, with a population of approximately 1.1 million residents. The city is best known as the gateway to Angkor, one of Southeast Asia's most significant archaeological complexes, which draws hundreds of thousands of visitors annually. Located in the northwestern region of the country, Siem Reap sits on the Siem Reap River and serves as both a cultural and economic hub for the province. The city's modern infrastructure contrasts with its historic temples and colonial-era buildings, creating a unique blend of ancient and contemporary architecture. Beyond the temples, Siem Reap has developed into a major tourism center with diverse attractions including night markets, traditional silk workshops, and floating villages on Tonlé Sap Lake.

Siem Reap is situated in northwestern Cambodia at coordinates 13.5°N, 104.0°E, placing it roughly 240 kilometers northwest of the capital Phnom Penh. The city lies in the Tonlé Sap region, characterized by seasonal flooding and abundant water resources that have supported human settlement for millennia. The landscape around Siem Reap transitions from lowland plains to more elevated terrain, with proximity to the Kulen Mountains to the northeast. The city operates on Indochina Time (UTC+7) and experiences a tropical climate with distinct monsoon seasons. The region's geography has historically made it a natural crossroads for trade and cultural exchange within mainland Southeast Asia.
Siem Reap's prominence dates to the Khmer Empire period, when the nearby Angkor complex served as the empire's capital from the 9th to 15th centuries. The city itself developed as a settlement supporting pilgrims and traders visiting the temple complexes. During the French colonial period, Siem Reap was incorporated into French Indochina and gradually modernized with colonial infrastructure including administrative buildings and hotels. The city's name derives from Khmer words meaning 'Siam Defeated,' referencing historical conflicts with neighboring Thai kingdoms. In the 20th century, Siem Reap experienced significant disruption during the Khmer Rouge period but has since rebuilt and emerged as Cambodia's primary cultural and tourism destination. The preservation and restoration of the Angkor temples have made Siem Reap central to Cambodia's international cultural standing.

The city center offers the widest range of accommodation and dining options, with hotels and restaurants concentrated near the Old Market (Psar Chas) and the riverside area. The Siem Reap River waterfront has become increasingly developed with mid-range and upscale properties offering river views. The area west of the city center provides quieter residential neighborhoods with boutique guesthouses and smaller hotels. Angkor Archaeological Park is situated approximately 5.5 kilometers north of the city center, with numerous accommodations available near the park gates for early temple access. The Pub Street district offers concentrated nightlife and entertainment venues alongside budget-friendly lodging. For travelers seeking traditional Cambodian experiences, homestays and community-based tourism options operate in villages within 15–30 kilometers of the city center.
Siem Reap International Airport (REP) is the primary entry point, located approximately 7 kilometers south of the city center. Direct flights connect Siem Reap to major regional hubs including Bangkok, Hanoi, Ho Chi Minh City, and Phnom Penh, with several carriers operating scheduled services. Ground transportation from the airport includes shared taxis, private vehicles, tuk-tuks, and hotel shuttle services. Overland routes connect Siem Reap to Phnom Penh (approximately 314 kilometers, typically 6–7 hours by road) and to Thailand via border crossings at Poipet and O Smach. Bus services operate between major Southeast Asian cities including Bangkok and Hanoi. The Siem Reap River provides historical water-based access, though boat services are primarily used for tourism rather than commercial transport today.

The cool season from November to February offers the most favorable weather, with lower temperatures and minimal rainfall, making it the peak tourism period. Temperatures are typically moderate during these months, ranging from 20°C to 28°C, reducing heat-related discomfort. The hot season from March to May brings temperatures exceeding 30°C, with May often the warmest month. The monsoon season from June to October brings substantial rainfall and higher humidity, though fewer tourists visit during this period, resulting in lower prices and shorter queues at temples. Water levels in Tonlé Sap Lake rise significantly during the monsoon, creating dynamic ecosystems and floating village conditions. October is often considered a transitional month with declining rainfall and improving weather conditions while tourism remains moderate.
Tourism is the dominant economic sector in Siem Reap, driven primarily by visits to Angkor and other archaeological sites. The hospitality industry, including hotels, restaurants, and tour operators, employs a significant portion of the local workforce. Traditional sectors including agriculture, fishing, and craft production remain important, particularly in surrounding rural areas. Small businesses including souvenir shops, silk workshops, and food stalls proliferate in tourist areas. The city has experienced substantial investment in infrastructure over the past two decades, including hotel development, road improvements, and utilities expansion. International organizations and NGOs maintain offices in Siem Reap focused on heritage conservation, community development, and cultural preservation. The seasonal nature of tourism creates employment fluctuations, with higher employment during peak months and reduced activity during monsoon season.
