Old Gamboa Road is the old road between the town of Gamboa and Panama City. This 4.4 km section of old road parallels Gaillard Highway, the main road to Gamboa. At the Summit Gardens turnoff, turn left (instead of right to Summit Gardens), cross the railroad tracks, and then turn right a few hundred yards past the railroad tracks onto the road. The Summit Ponds are near the beginning of this road.
The north end of the road is reached from the intersection with the Gaillard Highway. It's the second road to the left after passing the entrance to the El Charco Trail.
