At the end of the bridge, there is a Naga staircase leading to the temple chedi and other elements still under construction. It is up to you to choose where you want to start, with the temple but the road to get there is longer, or with the bridge easily accessible from main road 11.
There is no public transport to come Wat Phrathat San Don. The best to come is to have your own transportation or hire a driver. Access to the beginning of the bridge is on the side of road number 11 in Phitsanulok - Lampang direction. From Lampang, head towards Phrae, you will see signs indicating where to u-turn for a few hundred meters before arriving at the bamboo bridge (right after the Thai Thai coffee). If you do not have any mean of transport, see with your hotel or negotiate with a yellow and green car to take you here, wait for you and take you back to Lampang city.
