The promontory is composed of white, medium-grained sandstone known as the 'Longdong Sandstone' formation.
Climbing routes here are primarily traditional, though many have been bolted for sport climbing.
The area is home to unique intertidal zones that support a high diversity of marine life, including sea urchins and anemones.
It is recognized as one of the most stable geological regions in Taiwan, resulting in high-quality, durable climbing rock.
The site features a distinctive 'cuesta' topography, where one side of the ridge is steep and the other features a gentle slope.
Longdong Bay Promontory is Taiwan's premier rock climbing destination, featuring massive sandstone cliffs that rise directly from the Pacific Ocean. The site is geologically significant for its hard, erosion-resistant sandstone formations dating back roughly 35 million years. It offers a well-marked coastal trail that navigates along the cliff edges, providing unobstructed views of the Northeast Coast National Scenic Area. The area is a hub for outdoor enthusiasts, including scuba divers and snorkelers who frequent the protected bay waters. Vegetation is characterized by wind-swept, salt-tolerant plants adapted to the harsh maritime environment. The promontory serves as a distinct geographical boundary where the mountainous terrain of northern Taiwan meets the East China Sea. It is managed by the North Coast and Guanyinshan National Scenic Area Administration.

Wear high-traction hiking shoes, as the sandstone surface is abrasive and can be slippery near the water.
Bring sufficient water and sun protection, as there is almost no natural shade along the cliff-top trails.
Check tide charts before heading to the shoreline, as high tides can submerge access paths to climbing bases.
Attempting to climb or hike during typhoon season or heavy rainfall, as the sandstone becomes dangerously slick and prone to rockfall.
Practice 'Leave No Trace' principles by packing out all trash; maintain silence near nesting bird areas during spring months.
