dont know of a college, but I know certain schools offer such courses but not usually for a degree, I think you would have to go for a Zoology degree
with cryptozoology being a special interest? Maybe someone else has more expertise in this field and can lead you the right way.
Unfortunatley, Cryptozoology is not being professionally taught yet at any school facilities, anywhere. This is probably do to the fact that it is not
a respected branch of science, yet. Cryptozoology is more of a hobby and all you really need is an interest and a basic knowledge in biology. At lest
thats what I have...
