The radar station was originally constructed for civil aviation and maritime surveillance in Northern Taiwan.
The location sits on the Caoshan ridgeline, which is part of the larger Teapot Mountain and Banping Mountain hiking corridor.
The white dome architecture was designed to house specialized electronic radar equipment capable of penetrating heavy coastal mist.
The area is a recognized hotspot for 'silvergrass sea' photography during the autumn months when the mountain slopes turn white.
The elevation provides a direct line of sight to Keelung Islet and the northern edge of the Taipei basin.
The site remains one of the few decommissioned military vantage points in Ruifang that is fully accessible to the public.
High winds at this altitude often force the closure of exposed trail sections leading to the station.
The radar station serves as a natural transition point between the rugged coastal geography of the Northeast Coast National Scenic Area and the volcanic landscape of Yangmingshan.
Caoshan Radar Station is a repurposed military surveillance facility situated on the ridgeline of the Caoshan trail system in New Taipei City. The site features a distinctive white dome that previously served as a radar installation to monitor maritime and aerial activity along the northern Taiwan coast. Visitors access the site via a mountain trail that traverses high-altitude grasslands known for seasonal silvergrass displays. The surrounding area offers unobstructed 360-degree views of the Pacific Ocean and the Keelung Islet. The station currently functions as a viewpoint and landmark rather than an active military facility. It is strategically positioned at a high elevation, making it a critical point for weather observation and coastal security perspectives. The site is noted for its wind-exposed environment, which necessitates careful navigation during inclement weather.

Bring a windbreaker or layers, as the high-altitude ridgeline is significantly windier and cooler than the town below.
Carry at least two liters of water, as there are no amenities or vendors once you begin the ascent.
Wear shoes with high-traction outsoles, as the paths can be muddy and slippery after rain.
Do not attempt the trail during typhoon season or heavy wind warnings; avoid starting the hike late in the day to ensure you descend before dark.
Practice 'Leave No Trace' principles; keep noise levels low to respect the quiet mountain environment.
