The shrine is built in a northern Chinese architectural style, and it is fitted into the terrain, nestled between folds of the mountain wall. The result is both delicate and solemn, a small building held in the arms of a huge cliff. Then there is the water. A clear spring bursts out of the rock face and falls in a ribbon of white that never stops, all year round. This is the Eternal Spring Waterfall, and it gives the shrine its name, which means Eternal Spring. It is one of the great sights along the highway. Behind the shrine, the trail turns vertical. A steep zigzag staircase is cut into the sheer rock, with 380 steps in all, and it is known as the Heavenly Ladder. It climbs first to Guanyin Cave, then continues past Taroko Tower to a bell tower. The bell tower is the highest point on the trail, and from there you look down on the winding river, the canyon, and the road with its tiny moving vehicles. A walking loop around the site makes the waterfall, the gorge and the river bends visible from different angles.
