Paved (this is the old Hwy #7 which we took into Kratie previously. Into Kratie at 57Ks, completing the circle route.

Cambodia 2002

Entire trip is Vietnam, Cambodia, Eastern Thailand, and Southern Laos

January, February 2002

Vietnam boarder to Svay Rieng 44 Ks

The route is flat on Highway #1. In 2002, the road was under construction. Only moderate traffic buty until the project is finished, it will be dusty.

Svay Rieng to Prey Veng 102 Ks

Highway #1 construction makes progress slow. At 20 Ks before the Neak Luang ferry in Kompong Soeung, take a right (north) on a quiet dirt road, which eventually turns west, goes on a levee past a reservoir and finally intersects with Highway #15 (the main road to Prey Veng). The Lonely Planet Bike Book outlines this route. We modified the route by taking a very interesting side route. The alternative road was good dirt surface. From the intersection with Highway #15 to Prey Veng, the road was broken blacktop. Easier riding for bikes than cars. If you go the Lonely Planet route or our alternative route, the distance is the same.

Prey Veng to Kompong Cham 78 Ks

Take Highway #15 north to Highway #7 west. The first 30 Ks are on excellent blacktop. The next 30 Ks are on bad, busted up, dusty blacktop. There are some modest hills. Traveling is tough, and there is light traffic. On Highway #7 there is more traffic. The road is just as bad. Just before the new Japanese bridge to Kompong Cham, the road becomes perfection. Construction continues so the excellent road is growing. Great views form the high bridge over the Mekong.

Kompong Cham to Phnom Penh 110 Ks

(It’s worth buying the Lonely Planet Bike Book just for this one-day trip.) Out of Kompong Cham on the good dirt road along the river on the Kompong Cham side. There is excellent biking, low traffic, flat, shady, scenic and very interesting. This road ends abruptly and is very poor, sandy dirt for 5 very tough Ks. Some walking. Then the road slowly improves until you get to Koh Kaong. Some students guided us thru here and on to Highway 6A (the main road to Phnom Penh) It’s only 3 Ks out to the highway and there’s really only one-way out. Highway 6A is a busy and very good, almost wide road. It’s busier toward Phnom Penh Finally you cross another Japanese bridge (great views) just before Phnom Penh.

Phnom Penh to Takeo 75 Ks

We followed the route description from LP (Lonely Planet Bike Book) these are all good roads. After Takhmau, 8 Ks, go right (south) at junction. This road becomes quiet. There are a few minor hills and there are some good short side trips.

Takeo to Kampot 85 Ks

This route is all on good roads. Highway #3 is a little busier. 13 Ks over to Highway #3 then left (South east). The scenery is nice. Kampot is an interesting town along the river. Then go thru Tani toward Kep. Highway #16 was reported to be impassable. We even checked into taking an auto train where the road was very bad but it was too complicated and the main route is good. The LP suggests a circuit to Kep. We didn’t go there.

Kampot to Sihanoukville/Kampong Som 100 Ks

This route is mostly flat with a few small hills and is in the LP book. Highway #3 is great biking. The road is quiet, good condition, and interesting scenery. It’s 52 Ks to the junction with Highway #4 (the main fast road PP to Sihanoukville). The last 20 Ks to Veal Rinh were under construction in 2002 and should now be improved. Highway #4 is the best road in Cambodia. There is truck traffic (going to the port). Sihanoukville is spread out but the rides to the other beaches are fun.

Sihanoukville/Kampong Som to Kaaong 85 Ks

This route is on Highway #4. Back to Veal Rinh (47 Ks). Early, the winds are light, and then there is a following north wind past Veal Rinh. After Veal Ring, the scenery is duller. The traffic is light and the following winds give out. No place to stay in Kaaong.

Kaaong to Kompong Speu 92 Ks

The route still follows Highway #4. Initially there are some hills to look at but then flat. Still a good road but toward Kampong Speu a dull ride and the road gets busier.

Kompong Speu to Phnom Penh 50 Ks

Highway #4 gets busier to PP. The road widens and you pass urban sprawl. Poor ride past the airport.

KHM.map.route.000000.1

Day ride #1 around Phnom Penh 50 Ks

Go 8 Ks to Takhmau and continue straight on paved road where Highway #2 head right to Takeo. Initially boring. Pavement ends and the road becomes rougher and follows the river. There are numerous small ferries that cross to a rough dirt road on the other side. There are loops away from the river into the rice fields and you see the interesting rural life.

Day ride #2 around Phnom Penh 80 Ks

The downside of these day rides is the roads in and out of PP. Leave PP on Highway #4, about 25 Ks to Highway #26. Go right (north) on a dirt road that is dusty but very very little traffic to Batt Doeng. In Batt Doeng go right (east) to Mt. Basat then take the “Dyke Road” to Highway #5, go right (south) to PP along the river. Even in the dry season, the countryside around the dyke road is verdant. It’s a good dirt road. This road must be repaired after every wet season.

An alternative shorter loop that is hard to find. Turn off Highway # 4 at about 15 Ks asking for Mt. Basat then take the Dyke Road back to PP.

Phnom Penh to Kompong Cham 120 Ks

Leave PP along the river and take the Japanese Bridge on Highway #6A. The route is all on very good wide paved roads to Highway #6 passing Skuon. (see Kompong Cham to PP description above for alternate route on dirt road. The turn off for this alternate route is at Koh Kaong). This route is easier, longer and less interesting with some traffic compared to the alternative.

Alternate route to Laos Border from Kompong Cham
**Kompong Cham to Stung Treng or Kratie

This road is reported to be rough. You can take a boat to either form Kompong Cham.

**Stung Treng to Laos Border

This is 64 Ks of very rough road and the border is not always open. It is reported that you can cross with a “tip”. The road in Laos from this border is excellent.

Kompong Cham to Kompong Thom 110 Ks

This route is not recommended. Take paved Highway #6 for 14 Ks to Traeung. Highway #21 goes north with sign posts for 97 Ks to Kompong Cham . This road starts bad (dirt, sand) and gets worse. We finally were led off this unused road through sandy paths to Highway #6 which is mostly broken but some is ok.

Kompong Thom to Siem Reap 145 Ks

(We only rode the first 5 Ks and last 16 Ks of this option) Reported as very rough and dusty. This is the bus route. 16 Ks before Siem Reap the road is excellent and it’s being constructed further. Eventually this will be a good road.

KHM.map.route.000000.2

Day trip from Kompong Thom to Sambor Prei Kuk 56 Ks

This trip is to visit some minor temple ruins. There are some signs. 5 Ks to Thnol Bek then right on a good dirt road and right again to Prei Kuk. You can extend your ride past the ruins to see the countryside.

Kompong Thom to Skuon 90 Ks

The road is mostly broken and some ok.

Skuon to Kompong Chhnang 103 Ks

Start out for 44 Ks on excellent Highway #6 to junction for Prek Kdam Ferry. Go 7 Ks on good road to the ferry. Turn off the ferry to the right (north) on Highway #5. This is an improved road with moderate traffic but there are many fast moving taxis. There are some small hills. From Kompong Chhnang we hailed the boat to Siem Reap.

Route we did not take
Kompong Chhnang to Pursat to Battamburg to Sisaphon

It is reported that this road is variable but generally very rough. The road beyond Battamburg is reported to be very bad.

Day rides from Siem Reap around Angkor Watt

Excellent roads are as good as it can get. We used the LP Bike Book for routes. We recommend the “calm roads to Quiet Temples” ride but cut out the northern part. Simply go out and back to Bakong on the roads south of Highway #6 and south of Siem Reap. It’s even easy to ride around Siem Reap. Also it’s 15 Ks to the ferryboat to PP. The last 3 Ks are on a very rough one-lane road, which is chaos a ferryboat time.

Siem Reap to Sisaphon 103 Ks

The first 15 Ks are blacktop to just past the turn off for the airport on Highway #6. Then the road deteriorates to very dusty but not too rough. The winds are fairly strong from the east, but the dust just sits on the road.

Sisaphon to Poipet and the Thai Border 45 Ks

The road out of Sisophon is very good until the last 15 Ks then awful. It’s dusty and a poor surface. Through Poipet, the road is bumpy dirt and not maintained. On the Thai side the road is like silk.

Road Stories

The boat to Siem Reap or Angkor Wat (2002 – This boat no longer runs)

We rode out of Phonom Penh to Kompon Chaang where we heard that the fast boat from Phonom Penh stopped for passengers on route to Siem Reap. No one in Kompon Chaang speaks English. We are operating on what we think they are telling us but have no real understanding.

We spend the night and arrive at the dock at 750AM for what we think is the 8:00AM boat. The locals direct us to a canoe with a small outboard motor and put our bikes with panniers attached in the front and we sit behind them. We slowly motor about 400 yards to a police houseboat. We clamor off the canoe and park our bikes next to the houseboat railing. The police officer points to seats at the other end of the porch for us to sit and act as ballast. At 9AM a little bigger canoe arrives. This time a man in a black t-shirt from the police station sits in the bow, then our bikes, then the driver and us. The wind has picked up, the river is wide here and the water is choppy. We bob and slosh to the middle of the brown river and wait. We spot a spray in the distance. A sleek fast boat materializes out of the spray. Peter says, “It’s not slowing down”, as it sprays past us. We slosh and bob back to the houseboat. Black t-shirt holds up two fingers as we are settling back on the porch, “two boat.” He disappears into the police houseboat.

Black t-shirt returns with an official brown police baseball cap and a long sleeve official gray shirt. We transfer into a still bigger canoe with a bigger motor. We bob back out to the middle of the river. Our now spiffed up and official Policeman stands in the bow with a Hail Hitler stance. Another fast boat materializes from another spray and slows – just a little. Is this going to be an instant reply? The canoe driver starts up the engine and we zoom along side the speeding boat. Four crew members are at the boat’s rail. It is split second timing. Two of the crew grab each bike while we are told to jump up. As I reach for the railing of the fast boat, a crew member grabs my wrists and swings me up so I can stand on the gunwale and hold the rail. We climb over the rail and look back, the canoe and policeman are a dot in the water. We ride the spray to Siem Reep.
