The post carriage began operating between Reichenbach and Thun in 1814. In 1901 a railroad was completed that linked the municipality with Spiez. This was followed by the Niesen train in 1910 and the Bern-Lötschberg-Simplon Railway in 1913. The new transportation links quickly changed Reichenbach into a tourist destination. The population grew and many vacation homes were built in the municipality. A military airport was built in the valley, but in 1994 it switched to a completely civilian airport. A secondary school was built in 1959-60.
