Here's why it's hard to say exactly how far it is:
* Beaumont has no direct coastline. The closest beach would be in Newport Beach or Laguna Beach, which are both about 60-70 miles southwest of Beaumont.
* Driving time depends on the route. You could take a direct route on the freeway or a more scenic route through the mountains, which would take longer.
So, while there's no direct distance to the ocean, Beaumont is considered quite inland and is not a beach town.
