Tips Cycling Tour Southeast Asia

Hi!

I'm in Phnom Penh right now.
I am doing the loop clockwise, I started cycling in Ayutthaya (BKK is busy and crowd!) and went towards north: Chiang Mai - Pai - Chiang Rai and Mae Salong.
Then crossed Laos border. Took a slow boat along Mekong from Huai Xuai to Luang Prabang (2 days). Then cycling to Vang Vieng, Vientiane and south to 4 thousand islands. Cycled south parallel to Mekong River is an off-road, very interesting.

At the moment I have done 2700km :)

Btw, I'm preparing a website/blog and update my trails in Wikiloc, I will send the links as soon as I got it.

North Thai and North Laos are difficult as there are heaps of steep roads and mountain passes. But awesome landscapes.
Thai: almost all paved/surfaced and better roads.
From Ayutthaya to Chiang Mai easy and not impressing landscapes, maybe you could skip.
Laos from Vientiane to south is flat or almost.
Cambodia: so far so easy, flat terrain too, doing averages km of 120 daily.

For me, better Laos & Cambodia as roads are worst and more authentic, less developped.
If I had to do it again, I definitely would spend more time in the north.

I'm cycling a mtb 29', so hard to find tires. Depending on what you are looking for, better road bike or mix race mix mtb.

Not sure if doing the loop anti-clockwise is better, cycling up along the Mekong means steady rise.

No worries to ask me.
Go for it, you won't regret it!!!
