-the hot springs outside of town are shallow but very relaxing. Early morning and late evening are the best times; bring an egg to boil or candles at night, but be sure, as the sign says, to 'keep the clean'
-Get an herbal sauna at Mr. Jan's. For just over a dollar you can have one of the most unique experiences in Thailand, covered in lemon and honey while sitting in a mentholated steamer. He also does massage and massage classes.
-There are two waterfalls that are within 10 km of the town and are both great day hikes. When going, both falls are on the town map that you can get at nearly any store or guesthouse.
-the Temple on the hill is a beautiful, serene spot on the way to the hot springs. A long flight of stairs leads up to a quiet courtyard and 30 foot reclining Buddha. There is a bell tower in the courtyard that is a great spot to watch the sun set over Pai valley.
Quick Tips:
Give yourself plenty of time. There are more things to do than can possibly be listed. Cooking courses, massage courses, motorcross, whitewater rafting, hilltribe visits, elephant rides, and trekking are only the beginning so give yourself time to participate.
Also, Sopong is a village just 40 km further down the road where there are quite a few different caves to explore. It is a smaller town than Pai with only a couple guest houses but it is well worth the visit and is not as popular (or over-populated)with westerners.

You can walk anywhere in this little town but to get out and see everything the area has to offer such as hill tribe villages, waterfalls,and hot springs it is better to rent a bicycle or a motor bike. Moto taxis are also available but unneccessary most of the time.
I think a motorbike is the best way to get to Pai from Chiang Mai as well. The roads are sealed and perfect all the way to Pai and the scenery is great winding through the mountains. This way you can have your own transport the whole time you are there. You can also rent a car or four wheel drive in Chiang Mai.
The other option is the bus. It can get quite crowded and hot on this four hour ride with a fifteen minute stop half way but it is cheap at 51 Baht. There is an air-con bus but I wouldn't expcet it to be any better. The bus runs about six times each day between 7am and 4pm.
