Beiguan Tidal Park

A dramatic coastal landscape where Qing-dynasty garrison ruins meet basalt reef shoreline
📍 Yilan · Toucheng Township · Binhai Road⛩️Historic Temples🔖Qing-Dynasty Garrison Pass · Basalt Reef Shoreline · Crashing Waves

Beiguan was an important defensive pass guarding Yilan from the outside during the Qing dynasty; a Qing-era stone marker of the pass is preserved here. The park's terrain is dominated by a basalt reef coastline. Waves crash against the rocks in a spectacular display, and trails allow you to get close to the reef formations. It is one of the representative scenic spots along Yilan's northern coast.

Highlights of Beiguan Tidal Park

The name Beiguan (Northern Pass) comes from the Qing-dynasty defence system: this was the northern gateway into the Yilan Basin, and the surviving stone marker records the establishment of the pass. Geologically, this section of coastline is volcanic-rock reef terrain; the basalt has been eroded by waves over time into a variety of reef formations, and the intertidal zone is ecologically rich. The park's trail follows the reef coastline and descends to lower reef platforms — but always check wave conditions for safety.

Beiguan is at the northern tip of Yilan County, right along Provincial Highway 2. It is about a 5–10-minute walk from the car park to the main viewpoints. When waves are large — especially during the northeast monsoon season (roughly October through March) — the spray is spectacular, but the reef surface is slippery and you must stay out of any warning zones. In summer the sea is calmer, making it safer to observe the reef ecology up close.

How to Make the Most of Your Visit

🌊
Autumn and Winter for the Best Waves (October–March)The northeast monsoon drives strong swells; the spray against the reef is at its most dramatic, but stay well clear of slippery rocks and observe from the viewing platform for safety.
🪨
Observe the Basalt Reef FormationsWave erosion has carved potholes and sea-erosion channels into the basalt. In summer when the sea is calm, you can safely approach to examine them — watch your footing on wet rock.
🏛️
Find the Qing-Dynasty Garrison Stone MarkerA Qing-era stone marker of the Beiguan pass is preserved within the park — a tangible record of Yilan's historical defensive layout, located near the trail head.
📸
Best Angle for Wave PhotographyShoot down from the high-point viewing platform on the trail to capture waves breaking on the reef with the Pacific as backdrop. A shutter speed above 1/500s is recommended to freeze the spray.

Practical Information

Getting There

  • By car: drive along Provincial Highway 2 to the northern end of Toucheng Township; Beiguan Tidal Park is signposted from the road and has a car park.
  • By public transit: take the TRA to Toucheng Station, then take a taxi or local bus — about 15 minutes. Check schedules in advance as services may be infrequent.
  • When waves are high, the reef surface is dangerously slippery. Follow all warning signs; do not enter any reef area that waves can reach.

Nearby Connections

  • Wushih Harbor Tourism Fishing Port is about 2 km to the south and can be combined with Guishan Island or whale-watching plans to form a northern Toucheng half-day route.
  • Toucheng Old Street is about 5 km to the south; the afternoon is a good time to browse the traditional buildings and have a meal.
