We visited several attractions in the park. Shakadang, Swallow Grotto were excellent and breathtaking. Also wanted to see Baiyang waterfall trail, but it was closed. All in all, the park was beautiful and very clean. However, falling rocks seemed to be very common in the park. Pls consult the park headquarters to borrow a helmet, especially if you plan to see the swallow grotto.
We took the Taroko route of the Taiwan shuttle bus. 台灣好行太魯閣線 Tickets can be purchased near the train station. It is a one-day or two-day pass with which passenger can get on and off various scenic attractions of the park at designated schedule. The only problem is that they tend to oversell tickets and be sure to line up early for a seat.
