Where do Muslims fast? The simple answer is anywhere! There is no particular place where someone should fast.
Remember the traveler does not have to fast. Even if you are traveling by plane you can break your fast. Remember, you have the choice of keeping your fast if you travel. It is up to you.
Some scholars say if it is not a stressful situation when traveling then you shouldn’t break your fast but if you do you have to make it up afterwards.
In conclusion, you can fast anywhere!
