The green-railed main stairway starts down near the reservoir: 110 steps (next four pics). At the foot are benches, a picnic table, the Pavilion, the steppingstones over the water at the foot of the falls (seventh pic), and the shorter south stairway on the other side of the falls.
The south steps don't go all the way up. You'll merge with the northside stairs after 38 steps, crossing the falls (eighth pic) on one of the short wood footbridges. The total is about 125 if you ascend from the south side.
Sixty-one mostly old wood steps (next four pics), widely spaced, some steep, will take you down the north side to the newer footbridge and either across to the boathouse or to trails around the island.
On an unoccupied picnic table near the boathouse were eight or so used books someone had left; helped myself to four paperback thrillers and circled round the lake to my starting place.
This part of GG park is especially popular with families and bird lovers, especially if you like ducks, geese (last pic), and other waterbirds or want to rent one of the boats.
