The Dolní Paseky mineral spring is a freely accessible mineral spring in Dolní Paseky, a local part of the city of Aš in the Cheb district of the Karlovy Vary region. The spring rises in the northeastern part of the Aš promontory on the right bank of the Bílý Halštrov, approximately 1.5 km east of the Czech-Saxon border. It is located in the Aš Highlands in the Smrčina geomorphological unit in the northeastern part of the Halštrov nature park. The bedrock of the spring in the alluvial sediments of the Bílý Halštrov consists mainly of concretions and pararules of the Ore Mountains-Smrčina crystalline rocks. The isolated spring is similar in its chemical composition, especially the content of Glauber's salt, to the mineral springs in Františkovy Lázně, but together with the mineral spring in Doubrava, which rises further north, it is classified as a group of acid springs in the wider area of the Saxon spas of Bad Elster and Bad Brambach.

The temperature of the spring fluctuates slightly between 8 and 9.6 °C, the total mineralization is 4,290 mg/liter. The content of dissolved carbon dioxide is around 1,800 mg/liter, which gives the mineral water a pleasant taste. The mineral water has a slightly increased content of silicon dioxide (SiO2) of 37 mg/liter. The pH value is 5.3. It has moderate radioactivity due to the trace presence of strontium. The yield is relatively low, according to measurements from 1974 it is 1.2 liters/min. The spring is said to have a beneficial effect on potency and longevity. Local residents who drank the water are said to have lived to a very old age. Drinking it is recommended for muscular rheumatism and metabolic disorders.
