Throughout his life Rath combined geological research with teaching and frequent travel, which were an integral part of geological research. He investigated greenstone rocks from Silesia, faded ore from Hungary and yellow apatite from Russia (Miass), participated in the geological survey of the Giant Mountains region (Sudetes, Bohemia).
In 1871 Rath took part in an expedition to Italy, the purpose of which was to study the effects of a strong earthquake in Calabria on October 4, 1870 (magnitude ~ 6.2).

According to the results of his travels in Germany, Switzerland, Austria, Norway, Italy, Hungary, Greece, Palestine, Rath published two volumes of travel notes that aroused great interest in society thanks to information not only about nature, but also about history, politics, religion, language, customs and manners of the peoples of these countries.
