Hint: "Sand to Stone" and "Salt over Snow" Achievements Made Easy
To get the "Sand to Stone" (In free ride, go from White Flats Camp to Pinwheels Ridge Camp without resorting to the chopper) and "Salt over Snow" (In free ride, go from Tsunami Reef Camp to Redrock Bluffs Camp without resorting to the chopper) Achievements easily, you CANNOT teleport directly from one camp to another. But you CAN teleport to a previous Vista Point / Livery and still get the Achievements.
Cheat: Easier Challenges
Although a vehicle is specified for each Challenge, immediately after a Challenge begins, you may go to the menu and switch vehicles to one that is faster or more suited to the terrain. You may only do this once, and if you need to restart, you will be stuck with the new chosen vehicle. So make sure it's a good choice, and you should have a much easier time completing the game.
Unlockable: Warrior Vehicle
Pause the game and enter the following code under "Bonus Codes" in the Options Menu to unlock the Warrior Vehicle: 18041851
