The East Coast Geopark possesses typical landscapes of coastal sandstones with volcanic regions, rapid declines in the accumulation of thick sediment, and sediment generated by plate collision. It is also a place to observe scattered coral reefs around and on volcanic rocks and how they were slowly uplifted. "Shitiping" is a typical site to display the dynamic geological formation. It has a huge area of coastal terraces composed of volcanic ash and tuff. Its landscapes include the uplifted terrains, wave-cut platforms, coral reefs, sea trenches, caves and cliffs. The potholes, in particular, are one of Taiwan's Number one geological sites
Bahsien Cave is located on the cliffs that face the Pacific Ocean in Shanjian Village in Changbin Township and have both geological and archaeological values. There are dozens of natural sea caves originally generated by the sea surf. Now they are scattered around 110-m-high cliffs with a rich Paleolithic pottery culture, named the Changbin Culture. Baxian Cave site has access to all trails leading to each cave, the biggest cave is Lingyan Cave. And the highest cave, Kuenluen Cave, is about 130 meters high, besides that, there are also, Chienyuan Cave, Joucheng Cave, Hailay Cave, Chaoyin Cave, Yongan Cave and Shuilian Cave. Due to the religious use of the cave originally, they all have a religious feel to them. It is the oldest prehistorical site found in Taiwan and is an important site that is ranked as a first class national historical site.
Sanhsientai is located in the north of Chengong Township in Taitung County composed of offshore islands and coral reefs. Sanhsientai is an agglomerate rock that now forms a headland. Gradual erosion has cut the neck that connected the mainland to the main island, which became a region of offshore islands rich in biodiversity. Due to a lack of human disturbance, screw pine trees can be seen everywhere on the off-shore island.
The name Hsiaoyeliu was gained because the topography and rock types of the area look similar to those of the Northern Coast Yehliu Geopark. Literary translation, Hsiaoyeliu mean "little Yehliu". However, a movement of local identity has made it a case for changing the name to mean something local. In terms of geomorphology, differential erosion of sandstones makes the place a good learning site for the young curious minds. With the close proximity of the Lichi Badland Geopark and the East Coastal Geopark, the community members have good practice for knowledge exchange, thus learning from each other. For instance, at geopark networking meetings, they work closely together. The working relationships of the two communities prove to be strong and robust as the ethnic combination and diversity of the two usually bring creative results in many occasions.
