A loop trail (2.4 km) leads from the Doi Pui Campsite to Doi Pui peak (uphill!) and back. From the peak you can continue to a View Point (680 m). The whole trail is in the forest and you’re above 1500 m, so it’s much cooler than in the city during the hot season. Bring insect repellent. To get there, rent a motorbike (or find a songthaew that takes you there) and drive all the way to Phu Ping Palace, continue on the main road, turn right after about 1 km (turning left will bring you to a mountain village) and continue on a narrow windy road for almost 4 km until you reach the Pui Campsite. Alternatively, walk all the way from Phu Ping Palace, there’s not much traffic. A sign marks the start of the trail.
