Taroko National Park near Hualien on the east coast of Taiwan is definitely worth a visit. I joined a group organised by Hualien Wow Hostel (press here for their details) and spent a day exploring the marble walled gorge with the Liwu River carving it’s way through.
Inside the gorge Eternal Spring Shrine Park was built to honour the hundreds of workmen who died building Highway 8 across the country from east the west. It also faces the East Gate archway, the entrance to the highway. During typhoon season water would be gushing down the hills and a fast rapid flowing river with dangerous currents shifting boulders along the way. You can make out on the hills how the water has eroded it’s pathways over thousands of years.
