No nonstop flight operates between Mumbai (BOM) and Siem Reap (SAI) as of 2026. The most common one-stop routing is via Bangkok (BKK on Air India or IndiGo, connecting to Cambodia Angkor Air or Bangkok Airways to Siem Reap). A KUL routing via AirAsia's Mumbai–KUL service and a KUL–REP (old IATA code for Siem Reap's former airport) or new SAI connection is an alternative, noting that Siem Reap opened a new international airport (Angkor International Airport, SAI) in late 2023; confirm your carrier lands at the correct airport. Via Singapore, Singapore Airlines plus Cambodia Angkor Air or Scoot connections work well.
Mumbai to Siem Reap covers roughly 4,400 km. A Bangkok connection involves about 5–5.5 hours for the BOM–BKK leg and around 1 hour 10 minutes for BKK–SAI, with a 2–3 hour transit, putting total time at 9–12 hours. Note that Angkor International Airport (SAI) opened in late 2023 and handles increasing international traffic; the old Siem Reap Airport (REP) is now domestic-only. Confirm which airport your flight uses when booking, as some legacy booking systems still show REP for Siem Reap.
Indian passport holders need a visa to enter Cambodia. The most convenient option is the Cambodia e-visa, available at evisa.gov.kh, which costs USD 36 (30-day single entry) and is processed in 3–5 business days. A Visa on Arrival is also available at Angkor International Airport for approximately USD 30. Ensure your passport has at least 6 months of validity beyond your entry date and carry a recent passport photo and USD cash for VOA. See /visas for the latest Cambodia entry requirements for Indians.
Cambodia's cool dry season (November to February) is the peak travel period — temperatures are 20–30°C and crowds at Angkor Wat are heaviest around Christmas and New Year. The shoulder months of October and March offer a balance of manageable crowds and good weather. The wet season (May–September) brings lush greenery and better photography with dramatic skies, and Angkor's moats fill beautifully, but afternoon downpours are daily. Book flights and Siem Reap hotels 6–10 weeks in advance for November–February travel; early-morning temple visits are strongly recommended to beat crowds at sunrise.
Angkor International Airport (SAI) is located about 50 km south-east of central Siem Reap — significantly farther than the old airport. Taxi transfers cost approximately USD 20–30 and take about 45–60 minutes. Pre-book a hotel pickup or use the official airport taxi counter inside arrivals. The ride-hailing app NHAM24 (Cambodia's local equivalent) is useful; Grab has limited coverage in Siem Reap. Many hotels offer shuttle services. The old Siem Reap Angkor Airport (REP) currently handles limited charter and domestic flights but may reopen to more carriers in future.
International Economy fares via Bangkok Airways or Cambodia Angkor Air generally include 20 kg of checked baggage. Air India international fares typically include 25 kg on the BOM–BKK leg; however, if the BKK–SAI segment is a separate booking on a smaller carrier, its baggage policy is different. Book through-fares on a single PNR when possible — it simplifies baggage handling and protects you in case of a missed connection. Cambodia Angkor Air's Economy class is a full-service carrier with meals on international routes.
Angkor Wat itself requires at least a full day to explore properly; the three-day temple pass gives access to 70+ Khmer ruins in the greater Angkor Archaeological Park. Sunrise at Angkor Wat (reflected in the west pond) is the single most photographed moment — arrive by 5:30 AM to secure a front spot. Beyond Angkor, Ta Prohm (the 'Tomb Raider temple' with tree roots enveloping the walls), Bayon with its 216 stone faces, and Pre Rup are essential. The Tonle Sap Lake floating villages and Phare Cambodian Circus (evenings) round out a 3–4 day itinerary perfectly.
No nonstop flight operates between Mumbai (BOM) and Siem Reap (SAI) as of 2026. The most common connection is via Bangkok (BKK), typically 9–12 hours total. Via Kuala Lumpur or Singapore are alternatives. Note: book for Angkor International Airport (SAI), not the old REP.
Yes. Indian citizens need a Cambodia visa. Get an e-visa in advance at evisa.gov.kh (USD 36, processed in 3–5 days) or pay approximately USD 30 for a Visa on Arrival at Angkor International Airport. Ensure your passport is valid for 6+ months from your arrival date.
Return Economy fares from Mumbai to Siem Reap typically range from ≈ ₹28,000 to ₹65,000 depending on season and transit. Bangkok connections are generally the most affordable, especially with Air India + Cambodia Angkor Air or Bangkok Airways combinations booked on a single ticket.
Angkor Wat faces west, so sunrise illuminates the rear of the main towers when viewed from the front pond — the reflection is magical. Arrive by 5:30 AM for a good spot; dry season (November–February) offers the clearest skies. Angkor Archaeological Park entry opens at 5 AM.
A minimum of 3 days gives you time for Angkor Wat, Angkor Thom (Bayon), Ta Prohm, and the sunset from Pre Rup. A 5-day visit allows for outlying temples (Banteay Srei, Beng Mealea) and a day on Tonle Sap Lake. One-day visitors from Bangkok are common but do justice only to the main temple.
As of 2026, the Angkor Park entrance fee is approximately USD 37 for a 1-day pass, USD 62 for 2 days (non-consecutive possible within 7 days), and USD 72 for a 3-day pass. Tickets must be purchased at the official Angkor Enterprise office and are photo ID-linked. Buy tickets the evening before for an early start.
