Need help getting the San Andreas Sightseer Achievement in GTA 5

Need help getting the San Andreas Sightseer Achievement in GTA 5. The Achievement says (Explore all of Los Santos and Blaine County.) But is it possible to get this Achievement in GTA 5 Online or is it just in Story mode?

:)

This game really makes me want to play GTA: San Andreas.

 

You can only get it in Story Mode. The online achievements all have GTA Online: in the description (like GTA Online: Reach Rank 25). Once you get the map all filled in when playing the story it should pop.

 

Flying a plane or heli up and down the map until all the fog is clear in single player will pop it.

 

Sounds like a easy Achievement just where can I find a Plane or Heli in SP?

 

Try driving around until you find one.

Better yet, try driving to the airport.

 

Will I get 3 stars on me the moment I enter the airport?

 

Don't you have Trevor's Frogger out at his airfield? He steals the helicopter after the "Three's Company" mission.

 

You can usually find a heli on top of the roof of the hospital near the strip club.

 

I completed this in online. Most in story but it is possible in online mode. Also unique stunt jumps achievements. Face Palm this thread James LOL. Helicopters can be found near the boat docks, Sandy shore airstrip, LS airport, hospital.

 

Only in Story Mode. The map in Story Mode slowly becomes visible as you explore new areas. In Online, the map is already "solid", so it wouldn't make sense to "explore it".

 

Mine was completed in online mode. I went over an area that I must have missed in story and it popped. Maybe it glitched or whatever but it did happen and I can assure you unique stunt jumps work online as well. Not sure about knife flights. Might try it
sometime.
