In Red Dead Redemption 2 you will automatically have a $250 bounty on your head for Blackwater and the New Austin area (including Armadillo and Tumbleweed).
To remove the Blackwater Bounty in RDR2: Reach the Epilogue in the Story. You can pay it off beforehand at post offices but the status will remain “Wanted Dead or Alive” so people will shoot you on sight.
There’s no other way to remove the Wanted Dead or Alive Status – you simply have to reach the end of the game. You can already visit the area but the bounty hunters will very quickly kill you so it’s not feasible to search for collectibles there until you’ve beaten the game. After Chapter 6 the bounty will be lifted and you can finally explore the full map. If you go there before then, you will just get killed within a few minutes.
Here’s a look at Blackwater and the surrounding map uncovered:
