Please translate the phrase "I travel therefore I am" into Latin. 

I am looking for a play on the philosphical phrase "I think therefore
I am" (cogito ergo sum). Therefore, the portion "I am" should entail
the concept of existence, or to be alive as a human being.

Hi jdodd-ga -

I suppose that travel these days might allow plenty of time for
philosophizing, and I'm happy to oblige you with:

       Itinero ergo sum  (I travel therefore I am)

Itinerare

If you wanted to indicate that you travel "far and wide" you could say:

       Peregrinor ergo sum  (I travel about therefore...)

Peregrinari

Good luck in your travels,

Hm, viago?

How about "peragro"? As in "Peragro ergo sum"

A lot of the Latin words often translated as "to travel" basically
have a simple connotation of "to go" or "to march"; I think "peragro"
has more of a connotation of "to wander" which might be more to your
liking, if that's the kind of thing you want to imply with "travel".

But I could be mistaken...

Thank you for the help!  A friend of mine suggested "eo ergo sum", but
I think your suggestions are more specific.

Again, many thanks!

We do not speak proper English and you are asking for Latin.Good Luck.
