Walking from the trail next to the Idas Hall in Bullock Bay, you can reach the Bullock Bay Suspension Bridge (Sanyue Suspension Bridge). The bridge is 196 meters long, with a bridge deck width of 2.5 meters. It is about 152 meters away from the valley. It spans the Liwu Valley from the edge of Buolo Bay Terrace. It is the longest span and the largest distance from the valley in Taroko National Park. From the suspension bridge, you can see the Liwu River winding and twisting, while the mountains on both sides are steep and stacked on top of each other. The view can extend upward from the valley to the distant mountains. To the east, you can see the Liwu Valley along the stream, and to the west, you can admire the majestic and steep Yanzikou canyon terrain.

The total length of the trail from Idas Hall to the platform on the north bank of the suspension bridge is 500 meters. They are all barrier-free trails and can be used by wheelchairs and strollers.

Liwu River has experienced many significant topographic uplift movements. Each crustal uplift will increase the height of the river bed, causing the river's downward erosion to intensify, forming a canyon topography. When the attack slope (outer slope) of the river suffers greater erosion, it is more difficult for the old river bed to remain; the accumulation slope on the opposite bank suffers less erosion and can survive. As the river continues to cut downward, the remaining old river bed is relatively elevated, forming a flat river terrace terrain. The Buluowan Suspension Bridge is located on the edge of the Buluowan Platform, where you can observe the narrow marble canyon of Yanzikou and the Buluowan River Terrace. It is a very good geological observation and interpretation point.

Shanyue Bridge was the longest iron suspension bridge in the Liwu River Basin during the Japanese occupation. Walking on the bridge overlooking the deep valley of Liwu River was extremely thrilling. The Japanese police who were dispatched to Taroko at that time saw that the bridge was tall and tall. It is so long that people are afraid of the road and can't help but make people think of resignation, so it is also called "Resignation Bridge". For tourists who come here, the Sanyue Bridge is an insurmountable and terrifying journey.

The Buluowan Suspension Bridge (Sanzuki Suspension Bridge) we see now is the fourth generation suspension bridge. The earliest Sanzuki Suspension Bridge was built during the Taroko Battle in Taisho 3 (1914) during the Japanese occupation. It was part of the Aiyong Line. The bottom of the Tachiwu River was crossed. The bridge was 154 meters long at that time. Its main purpose was to penetrate into the various ethnic communities in the Tachiwu River basin to achieve the purpose of governance; the second generation of the Sangetsu Suspension Bridge was built on December 12, 1930, the fifth year of the Showa era. It was completed on September 20. The bridge is 190 meters long and the bridge deck is 75 meters away from the valley. The third generation Sangetsu Bridge was built upstream due to cracks in the foundation of the old bridge during the construction of the gold-producing road in Showa 16 (1941). Rebuilt everywhere.

It is so long that people are afraid of the road and can't help but make people think of resignation, so it is also called "Resignation Bridge". For tourists who come here, the Sanyue Bridge is an insurmountable and terrifying journey.

The fourth-generation Buluowan Suspension Bridge (Shanyue Suspension Bridge) was set up to highlight the cultural history of Buluowan, while diverting tourists from the canyon section and creating viewing spots for the canyon from different angles. The design of the entire barrier-free trail allows people with disabilities, the elderly, infants and young children to enjoy the canyon scenery easily and safely.
