You can take the local bus from Chang Puak bus station in northern Chiang Mai. Fang is 152 km from Chiang Mai and it takes about 3 hours to get there by local bus. A ticket costs 80 baht. Halfway the bus stops for a leak and a snack.
From the north, Thaton is about 40 minutes away by songthaew, with Chiang Rai another 3 hours away.
Unfortunately it's not possible to hire a (motor)bike, because so few tourists visit Fang there are no rentals. Monmai Resort does offer car hire, but you have to be a guest of the resort and rates start from 1000 baht per day with limited availability. Discovering the area, which is really beautiful and therefore worth to do so, is only otherwise possible by going on a tour. Then you'll be driven around in a car, jeep, or pickup.
Huai Luk Royal Project (โครงการหลวงห้วยลึก) is located along the Chiang Mai-Fang route. Take a right turn at km95 for around 500 m. The project provides farming area to Hmong, Karen, and lowland farmers. It promotes, researches, and plants flowers, fruits, and vegetables for farmers. The produce of this project ranges from vegetables, fruits, and flowers such as cantaloupes, chrysanthemums, and peacock flowers to exotics like guava and pomegranate. The best time to visit is during November to March as agricultural produce is plentiful.
Wat Tham Tab Tao (วัดถ้ำตับเต่า), Amphoe Chai Prakan (on the Chiang Mai-Fang route). Take a left turn at an intersection for 3 km. The temple is situated between km120 and km121. The peaceful temple compound comprises a mid-pond scripture hall and Tap Tao cave, which is the highlight. The cave is somewhat smaller than Chiang Dao cave, but it offers the unique charm of Buddha images inside.
Doi Ang Khang, many of the best attractions in Fang are located on this mountain and it is well worth the effort to make the trip. Going with an organized tour may be the best way because the road up is best navigated by an expert. Try the locally grown tea at the tea factory and visit the beautiful gardens and fruit farms. Lunch at Doi Kham Coffee is extremely recommended (especially the delicious green curry). They also have fantastic cakes and desserts, and of course coffee!
Fang Lake, adjacent to Monmai Resort, this is a great place for a picnic, or go to the restaurant there to crank out some Karaoke!
Pong Nam Dang, small waterfall and park. Quite pleasant.
Fang Oil Fields, not half as boring as it sounds!
Wat Tha Thon, beautiful mountain temple with dragon sculptures and museum-style exhibits. It is quite different to many other temples in Thailand and offers spectacular views.
Doi Pha Hom Pok National Park, home to the hot springs (see below) and many other interesting attractions. Slow-cooking eggs in the spring water is popular with locals but not recommended due to the high amounts of sulphur that will penetrate the shell and obviously end up in your digestive system if you eat the eggs (and of course it smells terrible and is probably really bad for your health to stand there for a long time cooking the egg). There are bath houses for rent and even a "geyser". Plenty of other interesting things to see at Doi Pha Hom Pok than just the hot springs, including hiking trails, tours up the mountain (which must be officially booked from the park office), Thai massage, foot massage, beauty salon, coffee shop, park office with history and other exhibits, many other things that I forgot to mention also.
Sky Walk, located near Wat Tha Thon, this long, winding (and very steep) walkway. It cuts through the mountain forest and offers amazing vistas of the surrounding countryside. You will need to be very fit if you plan to walk back up. It is possible to continue further down the mountain using an older trail that has not been upgraded yet.
Fang Hot Springs (บ่อน้ำร้อนฝาง), Ban Pin, 8 km northwest of Fang. The 50 hot springs originate from simmering granite with temperatures from 90 to 100°C. The largest spring one spews out consistent steam with a strong scent of sulphur.
