Before you start this make sure the clock on the start menu has at least 6 or so hours of light. The sun rises at 6am and sets at around 5pm, use the transport hubs to make your way up to Blackwater. Bring up your map and then move down to the bottom left hand corner and place a marker at Escalera. Once you're ready make your way from Blackwater down to Escalera, be careful to avoid other players, as most will shoot at you regardless.
Make sure that Blackwater and Escalera have appeared at least once on your screen so you know that you're in the right area. If you're slightly outside the town areas it will not register that you have entered the town.
