Can you go to each region with a character or do you have to make a new one

Title says it all, I am new here so I just wanted to know if I could travel to each region

Yes you can travel to each region on one character. You can go to a new region after obtaining 4 badges in a region. The method of switching regions are talking to a sailor in either Vermilion, Slateport, Pastoria or Castelia respectively. If you accidentally switch to a new region or a wrong one you can talk to your mother in the region you just switched to to go back to your previous region. This function only works until you receive your second badge. After you get your second badge you have to continue playing that region until you obtain your fourth badge to switch regions. 

 

Hopefully this answered everything!
