Whe the mountain trail was in good condition, before the Morakot typhoon disaster hit on August 8, 2009, it took around 3 to 4 hours walk along the right bank of Ailiao River to reach the old Haocha village from new Haocha. After the typhoon in 2009, the trail leading to old Haocha was cut off. After several explorations and investigations by the tribesmen, the old trail was repaired, the falling rocks were removed from the road, and ropes were erected on the cliff, which made the trail passable again.
At present, to get to old Haocha you need to go through the Taiwan Indigenous Peoples Cultural Park in Majia Township, arrive at the end of the Haocha industrial road, and walk along the south Aliao River for about 3.4 kilometers to reach the flooded area of the new Haocha village. Continue for another 1.3 kilometers to reach the old hiking entrance and then follow the traditional route to old Haocha. The difference in altitude is about 830 meters. Some sections of the road are cliffs, which are extremely dangerous, and the whole journey takes around 7 hours to complete.
