Top attractions in Cambodia

Cambodia boasts an impressive array of attractions spanning ancient archaeology, cultural heritage, and natural wonders. Whether you're seeking spiritual enlightenment at sacred temples or relaxation by turquoise waters, Cambodia delivers unforgettable experiences.

  • Angkor Wat — The world's largest religious monument and a UNESCO World Heritage site, this 12th-century temple complex is a breathtaking masterpiece of Khmer architecture.
  • Tonlé Sap Lake — Southeast Asia's largest freshwater lake, famous for its floating villages, diverse wildlife, and spectacular sunsets.
  • Phnom Penh — Cambodia's vibrant capital city featuring the Royal Palace, Silver Pagoda, and bustling markets alongside modern restaurants and nightlife.
  • Sihanoukville — A coastal paradise offering pristine beaches, island hopping opportunities, and water sports for relaxation and adventure.

Popular foods to try in Cambodia

Cambodian cuisine is a delicious blend of flavours influenced by Thai, Vietnamese, and Chinese cooking traditions, emphasizing fresh ingredients and aromatic herbs. Street food and local restaurants offer authentic dishes at incredibly affordable prices, making culinary exploration a highlight of any visit.

  • Nom Banh Chok — A fragrant fish curry noodle soup served with fresh vegetables and herbs, considered Cambodia's national dish.
  • Amok — A creamy curry dish made with fish or chicken, coconut milk, and spices, traditionally cooked in banana leaves.
  • Lok Lak — Tender marinated beef stir-fried with vegetables and served with a tangy lime-based dipping sauce.
  • Samlor Machu Teung — A refreshing sour soup combining tamarind, pineapple, and fresh fish with vibrant herbs and spices.
  • Num Pang — A beloved street food sandwich filled with grilled meat, pâté, pickled vegetables, and fresh herbs served on crusty bread.

Best time to visit Cambodia

The best time to visit Cambodia is from November to February, when the weather is cool and dry with minimal rainfall, making it ideal for exploring temples and outdoor activities. During these months, temperatures range from 20-30°C, and visibility at Angkor Wat is exceptional for photography and sightseeing.

The monsoon season from May to October brings heavy rainfall and higher humidity, but offers lush green landscapes and fewer tourists. March to April is extremely hot and humid before the rains arrive. If you don't mind the heat and occasional showers, visiting during shoulder seasons can mean better deals and a more authentic local experience.

What to pack for your visit to Cambodia

Cambodia's tropical climate and temple exploration require thoughtful packing to stay comfortable and respectful. Prepare for heat, humidity, occasional rain, and temple dress codes when planning your luggage.

  • Lightweight, breathable clothing — Cotton and linen garments help you stay cool in Cambodia's intense tropical heat and humidity.
  • Respectful temple attire — Pack sarongs, lightweight pants, and shirts with covered shoulders to comply with dress codes at Angkor Wat and other sacred sites.
  • High SPF sunscreen — The equatorial sun in Cambodia is intense; protect your skin with SPF 50+ sunscreen and reapply frequently.
  • Comfortable walking shoes — Sturdy, breathable shoes are essential for navigating temple grounds and exploring uneven terrain.
  • Rain jacket or poncho — A lightweight, packable rain cover is crucial for Cambodia's unpredictable tropical downpours, especially during shoulder seasons.
  • Your uPhone eSIM — Stay connected throughout Cambodia with seamless coverage from major local networks including Cellcard, Smart Axiata, and Metfone, ensuring reliable data and calls wherever you explore.

Frequently Asked Questions

Everything you need to know about your Cambodia eSIM

Coverage is concentrated in urban areas and along major roads. Large parts of the Cardamom Mountains, northeastern Mondulkiri and Ratanakiri provinces, and the Tonle Sap lake area have limited or no service. You should not rely on connectivity in those regions.

Smart Axiata and Cellcard operate 3G on B1 (2100 MHz), which some older US-market phones lack. Your phone may still connect to their 4G networks (B1, B3, B5) or 5G (n78) if supported. Without 3G fallback, coverage gaps may be more noticeable in rural areas.

Your eSIM will connect to one of the three local operators: Cellcard, Smart Axiata, or Metfone. All three offer 4G on bands B1, B3, and B5, and 5G on n78. The specific network depends on signal strength and roaming agreements at your location.

This eSIM is for Cambodia only and does not include coverage in neighbouring countries such as Thailand, Laos, or Vietnam. If you cross the border, you will need a separate eSIM or plan for that country to maintain service.

Local SIM cards in Cambodia often require passport registration. With this eSIM, no local ID or registration is needed. You can install it before you travel and activate it upon arrival without visiting a store or showing documents.
