Wishing someone safe travel is part of almost everyday conversations in life, especially if you are a student of Spanish as your social circle will surely expand and you will have more reasons to wish your friends around the world a happy trip.
And, oddly enough, the expression “safe travels” is not used in Spanish. They have a different way of wishing for safe travels, as the direct translation of “safe travels” sounds quite strange to Spanish speakers.
Also, remember that Spanish is one of the most spoken languages in the world, so it is likely that on your adventures you will make some Spanish-speaking friends that you will have to say goodbye to and wish them a good trip.
