The beautiful lake Hvass Sø is a small but yet long lake located in Rold Skov a bit south of the lake Store Økssø.
The lake is surrounded by a variation of coniferous and is artificially founded. The lake was formed in 1959 when the construction of a dam was established.
Hvass Sø is named after the former forest supervisor Jens Hvass.
During spring and summer time the lake is a place where birds and insects love to be. Especially the colourful dragonfly is often seen flying above the lake.
