I do all my trips in the north by Honda Dream, so it takes a bit longer than you lot, but you can take a Dream just about anywhere, if you're patient! Below is a trip (an edited version of a story from my website, hence the accommodation recommendations and backpacker tone) I did a week ago -- some is pretty old hat, but the roads and views around Phu Chee Fah were tremendous -- hope you find it interesting. Route is Chiang Rai - Mae Chan - Mae Salong - Doi Tung - Mae Sai - Chiang Saen - Chiang Khong - Wiang Kaen - Doi Patang - Phu Chee Fah - Thoeng - Chiang Rai Day One - Chiang Rai to Mae Salong Leaving Chiang Rai by mid morning, head north up the boring and heavily trafficked Route 1 until you reach Mae Chan, taking the left turnoff for Mae Salong. Immediately the riding improves along this winding mountain road. Traffic is light to non-existent and the scenery spectacular. Depending on the weather, the visibility can be as low as 20 metres and the weather cold and clingy, so dress accordingly. Arriving at Mae Salong, check in at the comfortable and cheap Shin Sane Guesthouse, or the Khum Nai Phol Resort for those with more cash. Spend the afternoon riding up to the chedi summit, sampling tea and dried fruits and explore nearby villages. Day Two - Mae Salong to Mai Sai Leaving Mae Salong after a hot breakfast and loads more piping hot tea, head north from Mae Salong along a back road that runs along deserted mountain top roads, with pleasant views and cool air the whole way. On leaving Mae Salong you'll come to Baan Sam Yeak (three way village) where there is a checkpoint, turn right here and continue until you reach another three-way intersection where the left turn is signposted for Doi Tung -- take this road. Doi Tung is the centre of a number of Royal projects, and while you can also visit the Royal Residence, the Royal Gardens are what should not be missed. Rather than back-tracking down 1149 to Route 1, continue on through Doi Tung for an outstanding ride due north along the Burmese border. There are a bunch of checkpoints along this road, all but one were unmanned when we passed. At times of heightened security, this road could well be closed -- expect to see Burmese flags flying out of villages on the left side of the road. As you near the downhill slide to Mai Sai the views, both of over Mai Sai and Burma are breathtaking. The last downhill part of this road is very steep and slippery -- be careful! Arrive in Mai Sai in time for a late lunch, do some shopping in the market and cross to Burma if you wish. The Mai Sai Guesthouse has the best budget bungalows in town. Day Three - Mai Sai to Chiang Saen This is the easiest day of riding so far, in fact you could easily push on from Mai Sai if you didn't want to stay there a night. An easy ride of rolling hills, the main attraction en route is the Golden Triangle Tourist Disaster Area -- we'd suggest not even slowing down. Chiang Saen is a historic town and there are a bunch of ruins that are easily visited from the centre of town. There are also two hill-top temples -- one to the east of town and one to the west, and both are worth visiting. Day Four - Chiang Saen to Chiang Khong This easy ride has two options -- a riverside stretch or a hilltop route. Personally I prefer the hilltop route as the views are better, but the riverside stretch takes you by a few villages with relaxing rural scenery. Regardless of which route you take, the ride is smooth and easy, with the last stretch into Chiang Khong running along the bank of the Mekong. Once in Chiang Khong check in at Baan Ta-Mi-La or the Baan Rim Ta Ling Homestay, and be sure to drop into Lomtawan for some surprisingly good Thai spicy salads. Day Five - Chiang Khong to Phu Chee Fah This is where the fun really begins. Leave Chiang Khong on 1020 until you reach the left diversion for Wiang Kaen, and begin the trip to Doi Patang and Phu Chee Fah. Eventually you'll reach a t-junction with Phu Chee Fah signposted in both directions, the right road will take you via Thoeng and is a far easier, though longer route and means you'll need to do a long backtrack if you want to see Doi Patang. The left route goes up what begins as a amazingly good and very scenic road then degenerates into a very steep, windy, badly potholed and very muddy mess -- it is worth persevering with though as once you get up to the main north-south running elevated road the road is excellent, except for the occasional chuck of erosion damage. On weekdays expect next to no traffic whatsoever. The sign posting in this area isn't too good but most of the junctions have at least a few shops around, so it isn't difficult to get directions. Once you start heading south, you'll eventually reach the left turnoff to Doi Patang which runs for about 2km, after which there is about a 200 step climb to the summit. The views from here are spectacular and you can see the Mekong in at least two places. Once you're done staring at Laos, backtrack to the main road and continue south to Phu Chee Fah. Long popular with Thai tourists, this place gets barely a trickle of western visitors -- go there mid week in off season and chances are you'll have the entire place to yourself. There are three sets of accommodation, one about 2km north of the Phu Chee Fah turnoff, one 1.5 km north and another 100m south of the turnoff. In the low season the bunch of places south of the turnoff will be your best bet of finding somewhere open. Take the Phu Chee Fah turnoff for a couple of km to the carpark, from where it is a 700m climb to the breathtaking views. Overnight in Phu Chee Fah -- camping is allowed near the summit -- it can be very cold and windy! Visit the viewpoint before dawn -- I suggest being sure to set your alarm for 4.30am rather than 4.30pm. Day Six - Phu Chee Fah to Chiang Rai The last leg of the trip, head north from the Phu Chee Fah turnoff till you reach the left hand turn for Thoeng running down 1155. Before you hit Thoeng you'll reach the junction with 1021 which leads onto another great loop via Phu Lang Ka (but that is another story!), instead turn west to Thoeng from where you can then continue straight on via 1020 for the busy road to Chiang Rai or take routes 1020 (north) and 1152 for a more scenic, with the occasional karyst and less-trafficked route back to Chiang Rai.
