The beach derives its name from two large, lion-shaped rock formations that were once more prominent before coastal erosion altered the coastline.
The area is geologically part of the Yilan Plain's eastern edge, characterized by sediment deposits from the nearby mountains.
The beach is a known nesting or transit point for local coastal bird species due to the relatively low foot traffic compared to nearby Wushi Harbor.
Coastal currents here can be unpredictable, making it a spot favored by experienced surfers rather than casual swimmers.
Shuangshi Beach, or Double Lion Beach, is a rugged coastal stretch in Toucheng, Yilan, known for its distinctive dark volcanic sand and rocky outcrops. It serves as a popular regional spot for surfing due to its consistent swell patterns caused by unique offshore geography. The beach is bordered by dramatic cliffs and offers a direct view of Guishan Island across the Pacific Ocean. Unlike more commercialized beaches in the area, it maintains a wild, undeveloped character with limited infrastructure. The terrain includes a mix of pebble and fine sand, varying significantly with seasonal tides.

Wear sturdy footwear as the transition between sand and sharp volcanic rocks can be difficult.
Check local weather alerts for Yilan as surf conditions can shift rapidly during typhoon season.
Bring your own shade and water, as there are no facilities or stalls directly on the beach.
Do not attempt to swim in areas with strong rip currents or during high-tide cycles when the waves break directly onto the rock wall.
Respect the 'leave no trace' principle as there are no trash collection services; wear proper water shoes for safety.
