Everything that’s worth doing, you can do along Chicago’s lakefront.
Seniors in Speedos climb out of Lake Michigan after swimming laps. Chess players hunch over boards in a 1957 pavilion that looks like the Jetsons’ carport. Young people gather for beach volleyball and paddle kayaks in the shadow of yachts.
Overhead, a biplane pulls a flapping beer banner through the sky.
Is this Fort Lauderdale? No, but you couldn’t tell from the string of beaches, golf courses and marinas.
On fine summer days, the city and all its tourists converge on Lake Michigan and its bright Listerine-colored water, dotted by white sails. In its parks, people skate, bike, jog, fish, fly kites and play tennis.
When we were in Chicago one Labor Day weekend, we saw the whole thing on bikes, riding the 18-mile Lakefront Trail from end to end.
The first afternoon, we rented bikes at Millennium Park and made our way to the lakefront, passing gourmet picnickers with hibachis and tourists clicking away at Buckingham Fountain.
Crossing the Chicago River, we threaded our way through crowds heading to Navy Pier and rode into Olive Park.
At an overlook, we gazed across the water at elegant high-rise apartments on shoreline that was underwater until a character named George Streeter paid contractors to dump their debris there and then, with his new land, seceded from the city.
Many of the parks — Lincoln, Grant, Burnham — also were created from landfill.
From Ohio Street Beach, we rode to busy Oak Street Beach and Lincoln Park. Amid a stream of skaters and bicyclists, we passed the Chess Pavilion and Theater on the Lake, where local troupes stage plays in summer.
At Belmont Harbor, we circled the marina and stopped to watch dogs playing on a spit of sand.
We found a bird sanctuary amid the dunes at Montrose Harbor and fly fishermen casting lines from concrete risers. But on the other side of the point, we lost sight of the downtown skyline and turned back.
Back at Belmont, the dogs had jumped into the water. At Oak Street Beach, the lifeguards still were out in rowboats, keeping an eye on swimmers bathed in golden light.
“With all these beaches, Chicago looks like Los Angeles, the Los Angeles of the Midwest,’’ my husband said.
Even at dusk, Millennium Park was jumping. Crowds still circled the mirrorlike Cloud Gate sculpture, popularly known as the Bean, and from a distance, it looked as if a squadron of ants was marching across its silvery surface.
In its reflection, the sky had turned a deep midnight blue, and the city lights had multiplied into a galaxy, but most onlookers had eyes only for themselves.
Returning the next morning, we rented the last two bicycles and headed south. We passed the Field Museum and then rebuilt Soldier Field, whose old Doric columns hug new blue stands for Bears fans.
At the entry to Burnham Harbor, alongside McCormick Place, we stopped and sat on a ring of limestone blocks, watching the little dramas around us. A little boy dropped his fishing pole from the seawall into the lake.
Geese goose-stepped across the trail, trying to stay ahead of speeding cyclists. In the water, a young man gunned the engine of a ridiculously phallic cigarette boat, and we snickered as a svelte sailboat slipped easily past him.
The grounds of McCormick Place, called “Mistake on the Lake,’’ also have been redone, and now a waterfall courses down its monolithic flank.
Department-store magnate Montgomery Ward spent 20 years fighting the city and his fellow businessmen to keep this lakefront open to the public, largely succeeding through the 1909 Burnham Plan. The convention complex was seen as the most notable betrayal of his legacy.
We pedaled south, past more beaches and children’s “playlots’’ to Promontory Point. In a handsome stone park house with a round tower, three young women discussed plans for a wedding.
Water-skiers circled the point, and a sunbather stretched out on the limestone seawall, framed by the hazy downtown skyline.
We stopped to eat Polish sausages and freshly squeezed lemonade at 57th Street Beach, then rode on to 63rd Street Beach, which included a palatial Arts and Crafts beachhouse.Past the tree-shaded Jackson Park golf course, we rode through landscaped gardens up to the door of the South Shore Cultural Center, a 1908 Arts and Crafts manor with crystal chandeliers, French doors and bas-relief ornamentation.
Looking at our map, we saw we could use bike lanes to get within a few blocks of Indiana if we kept riding.
But we turned back, stopping to watch cormorants diving for fish and retrievers fetching rubber bones.
At the Field Museum, we bought a Popsicle from a cart, near a long line of people waiting for the water taxi to Navy Pier.
We couldn’t bear to return our bikes until we had to, so we rode back to Lincoln Park and took the North Avenue underpass to Old Town, where we ate seafood cavatappi and cannoli on the geranium-bedecked sidewalk outside Orso’s.
Chicago has come a long way since 1904, when muckraker Lincoln Steffens called it “unlovely and ill-smelling.’’ A century of sweat, slaughterhouses and sacrifices built this city, now overflowing with flowers.
