Cycling Angkor: Which Circuit, Which Months, and When Not To

Angkor is flat. The whole park sits on an alluvial plain and the circuits have no climb worth the name, which is unusual for a headline cycling destination and is the reason ordinary people manage it.

What the bike actually buys you is the space between temples. In a tuk-tuk the twenty minutes from Angkor Wat to the Bayon is twenty minutes of noise. On a bike it is forest, moat, and the long walls of Angkor Thom going past at a speed where you notice them. The causeway through the south gate, with its gods and demons hauling the serpent on either side, is a different experience at 12 km/h.

You also stop where you like. The small circuit has half a dozen minor temples that no vehicle itinerary bothers with - Thommanon, Chau Say Tevoda, Ta Keo - and on a bike they cost you nothing.

Distances: the small circuit is about 17 kilometres plus roughly 8 to get out from town and back, so call it 25 to 33 for the day. The grand circuit is about 26 plus the same access. Neither is far; the heat is what makes them hard.

November to February is when to do this. Mornings in the mid-twenties, low humidity, dry roads. This is a genuinely lovely ride and the single best way to see the park.

March to May is when not to. Temperatures reach the mid-thirties by late morning with no shade on the roads between temples, and the failure mode is heat exhaustion three kilometres from anywhere. If you are here in April and set on cycling, be moving by 05:30, be off the bike by 10:00, and do not plan an afternoon leg.

June to October, the rains, are more workable than they sound. The heat breaks, the roads are sealed and drain well, and the storm usually comes in one heavy afternoon hour. Carry a poncho, accept that you will get wet once, and enjoy an empty park.

Whatever the month, start at dawn. Both circuits are pleasant at 06:00 and punishing at 13:00, and dawn also puts you at the temples before the coaches.

A basic town bike rents for a few dollars a day in Siem Reap. Fine for the small circuit in cool weather; check the brakes and the saddle height before you take it, because nobody will adjust it for you.

An e-bike costs more and changes the trip completely. Green e-bikes are widely available in Siem Reap and are permitted in the park. The assist is what makes the grand circuit and the March-to-May months survivable, and it is the version most people over forty are happier on. Range is the thing to ask about: you want enough for 40 km with the assist on.

A guided bike tour adds someone who knows the back lanes. This matters more than it sounds - the direct roads between temples carry coaches, and the parallel dirt tracks through the forest are quieter, cooler and prettier. You will not find them alone.

A tuk-tuk is the honest alternative and there is no shame in it. Roughly USD 18-25 for a small-circuit day, the driver waits at each stop, and in the hot months it is simply the better call. Many people ride one day and take a tuk-tuk the next.

Mixed is the smartest option of all: tuk-tuk out to the far end, bike the loop, tuk-tuk back. Several operators run exactly that.

You still need an Angkor Pass and it is checked at the same checkpoints. Have it accessible; you will be stopping at barriers.

Traffic. The park roads are quiet by Asian standards but they carry coaches, and coach drivers are not expecting cyclists. Ride predictably, keep right, and be especially careful at the Angkor Thom gates, which are single-lane bottlenecks where vehicles squeeze past.

Water. Two litres minimum, and buy more at the temples - there are sellers everywhere and they are cheap.

Sun. There is no shade on the connecting roads. Long sleeves beat sunscreen for a whole day in the saddle.

A lock, because you will leave the bike at temple entrances for an hour at a time.

Lights if there is any chance of a sunset temple. It goes dark fast and the road back to town is unlit in places.

Do not ride the long outlying routes. Banteay Srei is 37 km each way and Beng Mealea further; those are car trips. The circuits inside the park are what the bike is for.

If you want the countryside rather than the temples, the lanes south and east of town are flat, shaded and genuinely lovely - rice fields, sugar palms and villages five minutes off the temple road.
