If you’re based in the USA and you’re looking to stream Grimsburg legally and for free (yes, 100% free), there’s a great method you can use right now (January 2026), here’s how to do it in a few simple steps:
At the moment, you can stream Grimsburg for free via FOX One, a service you can use for free via Prime Video with a free trial (even if you don’t have Prime Video). It’s super easy to start and cancel this free trial, and as long as you remember to cancel the FOX One free trial after you’ve watched the episodes and before the 7 days are over, you won’t be charged anything at all. There’s no catch – this is just a great way to stream this series for free in crystal-clear quality without any annoying pop-up ads or sketchy websites!
All you have to do is:
- head to the page for Grimsburg on Prime Video
- start the 7 day free trial for FOX One (there’s a button to do that on the page as shown in the image above)
- watch as many episodes of Grimsburg as you want within the 7 day period
- cancel the FOX One free trial before the 7 days are up (which is very easy to do within your Account settings)
- and that’s it – you just watched loads of episodes of Grimsburg online in excellent quality for free without paying anything!
As long as you cancel the FOX One free trial before the 7 days are up, no payments will be taken, as explained on the Prime Video Grimsburg page here.
Don’t have Prime Video? No problem!
You can do this very easily if you already have Prime Video, but even if you don’t already have a Prime Video account, it’s no problem – you can still start the free trial for FOX One as long as you have an Amazon account:
As long as you don’t mind watching the episodes within the 7 day period, it’s the best way of watching the show for free right now, legally, in excellent quality and with all the extras like subtitles. You can learn more and start the free trial on the Grimsburg page on Prime Video here.
