The closest Republic quick travel point is the Elarian Trail quick travel point (in the south of the map) and the closest taxi point is the Forward Camp Speeder speeder point (in the most south taxi point on the map).

3. Go Into the Ruins
Go up the stairs at the Forward Camp, and turn left and head into the Ruins of Kaleth to the west, and once you go up the stairs there, look for an entrance to a stone room with what looks like a blue cabinet or chest inside.

Inside, there will be a fallen pillar that you can climb up.

4. Climb up the Ramp
Outside, there will be another fallen pillar that acts as a ramp you can carefully climb up.

The datacron is to the right. Look for a shining white or purple beacon of light.
