Formosa, the beautiful island, boasts not only azure seas but also delicate sand dunes reminiscent of the Sahara, such as the Caotan Sand Dunes in Taoyuan, the Dingtou’e Sandbar in Qigu, Tainan, and the Jiupeng Desert in Pingtung. Shaped by nature, these landscapes showcase their most breathtaking beauty.
Sand Dunes at a Glance
Taiwan’s sand dune formations mainly occur in coastal areas and fall into three types:
1. Crescent Dunes: These dunes resemble a crescent moon, primarily formed by consistent wind directions.
2. Whaleback Dunes: Large, whaleback-shaped dunes are referred to as “whaleback dunes.”
3. Transverse Dunes: In areas with abundant sand but weak winds, the ridges of crescent dunes connect in a line, creating striped, transverse dunes.
4. Longitudinal Dunes: In regions with little sand but strong winds, dune ridges form parallel to the prevailing wind direction, known as longitudinal dunes.
Each of the three major sand dune areas has its unique charm:
Taoyuan Caotan Sand Dunes

Located in Guanyin District, Taoyuan, the “Caotan Sand Dunes” span four square kilometers and reach about seven meters in height. Their vast, majestic scenery has earned them the playful nickname “Taiwan’s Sahara Desert” among netizens. These coastal dunes are landforms created by the accumulation of sand due to waves and wind.
The dune area stretches from Laojie Creek in Dayuan District to the Daku Creek coastline in Guanyin District. The outermost part is Caotan Beach, while the inland area features towering dune formations, neatly lined with wind turbines that slowly turn with the breeze—offering a truly unique atmosphere.
The view of windmills against sandy beaches has become a popular photo spot and a filming location for idol dramas. However, strong northeast monsoon winds in winter can whip up sand that stings the skin, so it’s not recommended for travel during that time.

Tainan Qigu Dingtou’e Sandbar

Situated at the southern end of Qigu Lake, the “Dingtou’e Sandbar,” though called a “sandbar,” resembles a small desert due to the redirection of the Zengwen River’s course over four historical shifts, which deposited large amounts of sand into the Taijiang Inland Sea. This has formed a long, narrow strip of rolling yellow sand dunes.
Adjacent to Taiwan’s westernmost Guosheng Lighthouse, although somewhat remote, it is a hidden gem for many. Walking on the small dunes and taking in the scenery stretching from sandy land to the coastline helps one forget worries. Take off your shoes and socks, step onto the sand, and feel the grains slipping through your fingers.
This place is best visited in the early morning or at dusk. In the morning, white mist frames the blue sky, and at dusk, warm sunset hues layer across the dune ridges. Sit on the dunes and watch the sunset for a moment of peace all your own.

Pingtung Jiupeng Desert

Also known as the “Gangzi Desert Scenic Area,” the Jiupeng Desert is located in Gangzi Village, Manzhou Township, Pingtung County, at the mouth of the Jiupeng River. Covering over 200 hectares, it is the largest desert-like landform in Taiwan, often simply referred to as the “Jiupeng Big Desert.”
It was formed when northeast monsoon winds blew sand and silt from the Jiupeng River estuary and nearby coasts, depositing them over coastal forests. Over the years, lush greenery has been replaced by expansive sand dunes. Especially in winter when winds are strong, the dunes grow taller, and fine patterns are often blown into the sand, further enhancing the illusion of a true desert.
At Jiupeng Desert, you can not only walk slowly across the sands but also try the fun of “sandboarding,” sliding down from the dunes toward the coast. Additionally, there are many off-road vehicle excursions across the sands—making it the most diverse and uniquely playful among Taiwan’s sand dune sites.

In fact, Taiwan’s coastal sand dunes mainly serve to block ocean waves, reduce coastal erosion, and minimize seawater backflow. However, current coastal development has disrupted the natural balance of sand transport along the shoreline. Beyond admiring the scenic dunes, travelers can also participate in “sand protection activities” to better appreciate and cherish Taiwan’s precious natural resources.
