Sonia, you will also get a different answer depending on where the person you are asking the question is from (US/UK).
If I wrote your sentence, it would look like this: " I haven't BEEN travelling much, but when I have a chance to go, I try to experience..." (present perfect tense).
If somebody from Korea has been to England twice, he or she has travelled there and back twice. If somebody has GONE to England, he or she has not yet returned.
