The hill was created by the accumulation of 'bittern' and waste salt discarded during the traditional salt crystallization process.
Budai was historically one of Taiwan's most important salt-producing hubs, utilizing seawater evaporation in vast sun-dried pans.
The high concentration of salt crystals inhibits the growth of most local vegetation on the hill's slopes.
The surrounding Budai wetlands are recognized for their biodiversity and serve as a significant stopover for migratory birds.
Budai Salt Hill is a prominent landmark constructed from accumulated waste salt, representing the history of the once-thriving salt industry in Chiayi County. It serves as a visual testament to the Taiwan Salt Corporation's former large-scale salt production operations in the Budai area. The hill features a distinctive white, crystalline appearance that contrasts with the surrounding flat wetlands and aquaculture ponds. Visitors can observe the terrain of the former salt fields which have been partially converted into ecological zones. The site remains a primary historical point of interest managed under the Southwest Coast National Scenic Area. Its structure is made of hardened salt deposits that have settled over time, though it is no longer an active harvesting area.
The base of the hill from the boardwalk path, where you can capture the white elevation against the blue sky and surrounding green wetlands.
Wear sunglasses to mitigate the intense glare reflecting off the white salt surface during sunny days.
Bring a hat and sunscreen as there is minimal natural shade available near the hill.
Plan your visit to coincide with a trip to the nearby Budai Fish Market for regional seafood.
Do not attempt to collect salt from the hill as a souvenir, as it is protected property and often contains impurities.
Open year-round, but access may be restricted during severe weather conditions like typhoons or heavy rain which can cause the salt to dissolve.
Avoid climbing the salt mound directly to prevent structural erosion and for personal safety, as the salt surface can be abrasive and unstable.
