Beaver Travel has two agencies in Elgin and Forres in northern Scotland, as well as a corporate travel division based in Forres.
The agency was founded in 1973 and later taken over by the Widdowson family in 1999.
Clyde Travel Management director Paul Cronje said: “We are delighted to have Beaver Travel join the Clyde family.
“It is a brand we have long admired as friendly competitors to our own leisure division, Alba Travel. Both brands are established institutions in their own communities, having both been in existence for over 40 years.”
