There are many ways of translating this sentence to German, I'll give you just three common equivalents of your sentence in German:

Ich freue mich darauf, Deutschland zu besuchen.

Or:

Ich freue mich darauf, nach Deutschland zu reisen.

Or:

Ich freue mich auf meine Reise nach Deutschland.

By the way, "man" is spelled with one "n" only, it means "one" resp. "you" (How does one say ... in German? resp. How do you say ... in German?) and has nothing to do with the noun "(der) Mann" (= (the) man).

"Ich freue mich darauf, Deutschland zu besuchen."
