Little Oilpit is located on the Northwestern part of the Sevenstar Mountains, and is around 805 meters in height. Little Oilpit got her name because people in the past needed to cook sulfur after they mine the place, and the dissolved sulfur is yellowish like oil.Thus getting her name oilpit. The larger one is located on the Northeastern part of the Sevenstar Mountains, inside the National Park, and is called the Large Oilpit. This one is smaller, thus called the Little Oilpit.

　Yangmingshan National Park office has set up quite a service station here in Little Oilpit to provide tourists with valuable information.

　In addition, there are two watchspots here, which allows us to see the faraway Sevenstar Mountains, little Buddha mountain, Bamboo Hill, and the Bamboo lake.

　From Little Oilpit heading toward the Sevenstar Mountains one can see a place where it is perfect to get a view of the Mon grasslands. Past poets have described such a sight in their poetry and is a real treat for modern tourists to get a taste of the same feeling, espcially during the fall and winter season.

Little Oilpit hotspring smell of sulvur, looks grayish, and is acidic, with a pH value around 1.5~3﹒5, and a temperature of up to 99degC.

Little Oilpit's most distinguishing characteristic is the numerous unique geological sights,including puffholes, crystals, and collapses.

　The Datoon Mountain region's puffholes are greatest around the Large Oilpit,Little Oilpit, and Gengdsuping. They are known for the explosive geological activities.

　Although Little Oilpit is not as large as Large Oilspit, but its distribution is more unique in that the white smokes can be seen throughout the valley.

　The heat Little Oilpit's puffholes produce are extremely high and erosive, thus making the geological outlook of this region quite remarkable, with the height difference to run up to 100 meters. When puffholes sizzle and send heatwaves up, tourists get a real feel of the geological activities.

Due to the ongoing activities of the puffholes, the temperature of hotspring in this region run up to 99degC, and thus can not be used directly. What residents do right now is use pipelines to channel the heat and water for their use.
