Hi Murray,

Glad to hear you're enjoying Phu Quoc -- it's such a great spot! Where are you staying?

From Ha Tien you need a moto to the border and then onwards to Kep from where you can travel by bus, share taxi or moto to Kampot. From both Kep and Kampot there are bus and share taxi connections to Phnom Penh, see the respective transport sections for each spot for more details.

I travelled with my wife and our adult son from Phu Quoc to Sihanoukville on 15th Dec 2009 in one day.
First we took the ferry from Phu Quoc to Ha Tien at 8:30AM for 160.000 dong. At 10:15AM we arrived at Ha Tien. We got a "hot new" folder from Ha Tien Service Tourism on board about connections to Kep, Kampot, Sihanoukville (6:00AM, 15$ per person) and Phnom Penh (6:00AM, 15$ per person). At the pier in Ha Tien they additionally offered us a trip to Sihanoukville for 12:00AM for 20$ per person.
But there were three motorbike-drivers waiting at the pier. They offered us the complete trip for 10$ per person. So they brought us on their motorbikes to the border. After the formularities there was a Cambodian friend of theirs waiting with his car at the Cambodian side. We paid 30$ to the Vietnamese motorbike-drivers and went with the Cambodian to Sihanoukville without any problem.
The Cambodian brought us to our preferred hotel in Sihanoukville, the new GST-Guesthouse (13$ for a double).

We took the new minivan service from Ha Tien to Kep on Christmas Day, 2009. It leaves from the Tourist Office at Phuong Thanh Street about 1pm. Their address is: hatientourism@gmail.com. I would definitely recommend this service, at $15 each, it took us straight to our hotel in Kep, about 2 hours total. I didn't see any taxis at the border, so it's this or a moto.

No need to have them process your visa (they charge $25), you can do it yourself. Beware of one minor thing--the visa fee is $20 on the spot and if you decline to use the company's visa service, at the Vietnam border post, one of their moto-riding staffers may offer to take your completed form and money over to the Cambodian officers "for you" and will insist that it's $30. He's trying to make a few bucks off you. Just decline, be sure to keep your passport and walk over with the rest of the tourists--it's a few hundred feet of dirt track hike to get into Cambodia. There's a 'health check' for another $1 which consists of a dude sticking a dirty thermometer in your ear, then the hilariously-named "Formality Section" where you fill out an additional bit of paper.
Be sure to get on the proper van to Kep, Kampot and Sihanoukville, since the same company takes people to Phnom Penh as well.
