When you reach the west side of the reservoir, take the stairs that will lead up to the next oval shaped reservoir. Turn right on the access road and look for a trail heading up uphill on your left. This trail goes over a small hill and drops down again above the third and oldest reservoir in the park. Cross the access road on the trail to continue to the summit. This side of the park provides a natural wooded setting amongst huge Douglas-firs. Unfortunately, English ivy and blackberry bushes have invaded the understory. Soon you will reach a five trail junction. In the center is an old streetlight with a mossy patina. Turn left here to reach the summit.
A circular drive surrounds the top of the hill. It's is closed to cars, but there are usually plenty of cyclists, trail-runners and dog-walkers enjoying the summit. Birders with binoculars are often trying to eye the hundreds of species found in the park. From the statue of Mr. Scott, traverse northerly across the grassy hilltop amongst towering Douglas-fir trees. When you reach a bench near a large multi-trunked bigleaf maple, stop for a view of Mount Hood to the east. Continue north downhill past the playground to visit the crater, where there's an amphitheater and a basketball court. Turn west from the basketball court and look for the blue signposts to find Skunk Canyon, filled with salmonberry and small cedar trees. At the bottom of the canyon trail, follow the signposts across the access road, and past the tennis court to return to the lower reservoir and 60th Street.
All told, the hike is a quick ~2 miles RT with only 350 ft of elevation gain.
