Lake Geneva, Wisconsin has a mail carrier who jumps from boats and a telescope the size of a car

Lake Geneva’s got history, depth and a lot of surprises

Geneva Lake sits about 75 miles northwest of Chicago, carved by glaciers 20,000 years ago and fed by springs that keep the water clear enough to see the sandy bottom.

The Potawatomi called it Kishwauketoe, meaning “clear water,” and they were right.

Rich Chicago families discovered it after the Great Fire of 1871, and the town never really stopped surprising people since.

There’s a mail carrier who leaps from a moving boat, a telescope the size of a small car, and the house where Dungeons and Dragons was born.

The glacial lake that’s been clear for 20,000 years

Geneva Lake stretches 7.6 miles long and 2.1 miles wide, with a maximum depth of 135 feet. Glaciers carved the basin during the last ice age, and spring water filled it in.

About 95 percent of the lake bottom is sand, which is why the water has the kind of clarity you don’t expect from a Midwestern lake.

The Potawatomi lived along its shores for generations before European settlers arrived and renamed it after Geneva, New York, in the 1830s.

Wrigley and Schwinn summered here after the Great Chicago Fire

After the Great Chicago Fire of 1871, wealthy Chicago families loaded onto trains and headed north to Geneva Lake.

The Wrigleys, Schwinns and Swifts bought land and built grand summer estates along the shoreline, earning the area the nickname “Newport of the West.” More than 100 of those historic estates still stand today.

Their presence reshaped the entire town, turning what had been a Potawatomi homeland and a small settler outpost into one of the Midwest’s most storied resort destinations.

Walk 21 miles past private mansions on public land

The Geneva Lake Shore Path circles the entire lake, all 21 miles of it, and runs across private property the whole way.

Early settlers established that the 20 feet of land closest to the water would stay open to the public, and it still holds.

Each property owner maintains their own section, so the path surface shifts as you walk, from grass to stone to brick to wood planks.

The full loop takes eight to 10 hours, but you can start from access points in Lake Geneva, Williams Bay, or Fontana and walk as much or as little as you want.

A mail carrier jumps from a moving boat to your dock

Since 1916, mail on Geneva Lake has gone out by boat.

The carrier, called a jumper, leaps from the moving vessel onto a private dock, drops the mail, and jumps back before the boat pulls away. The Walworth II never stops.

It moves at about five miles per hour the entire route. This is the only mail-jumping boat in the United States.

About five or six jumpers work each summer, chosen through tryouts that test both athleticism and the ability to narrate the tour. Elaine Kanelos became the first woman to make the jump in 1974.

You can ride along on the 2.5-hour tour.

Step inside an 1888 mansion where almost nothing has changed

Black Point Estate went up in 1888 for Conrad Seipp, a Chicago beer baron who wanted a summer place on the lake.

The Queen Anne-style mansion has 20 rooms on seven acres, with 620 feet of shoreline on a bluff above the water.

You get there by boat from downtown Lake Geneva, a 45-minute narrated cruise, the same way the Seipp family arrived for decades. Nearly all the original furnishings are still inside.

The Wisconsin Historical Society runs tours from May through October, and a conservation easement keeps the shoreline from ever being developed.

The world’s largest refracting telescope lives 15 minutes away

Yerkes Observatory in Williams Bay was completed in 1897 and still holds the world’s largest refracting telescope, a 40-inch lens instrument that weighs about 12,000 pounds.

George Ellery Hale founded it, Chicago businessman Charles T. Yerkes paid for it, and the University of Chicago ran it for over a century before stepping away in 2018.

The nonprofit Yerkes Future Foundation reopened it for public tours in May 2022.

You can take a daytime building tour, a behind-the-scenes tour, or come at night and look through the historic telescope yourself.

Gary Gygax invented Dungeons and Dragons right here in town

Gary Gygax grew up in Lake Geneva and co-created Dungeons and Dragons with Dave Arneson in 1974. He founded TSR, the company that published the game, here in 1973.

At its peak in the early 1980s, TSR employed about 400 people in a town of fewer than 6,000 residents.

The Geneva Lake Museum has a permanent exhibit called “The Wizard of Lake Geneva” dedicated to Gygax and the game’s origins.

Every March, Gary Con, an annual gaming convention held in his honor, takes over the Grand Geneva Resort.

Louis Armstrong played the ballroom here during the Depression

The Riviera went up in 1932, during the Great Depression, built on pilings driven straight into the lake bed and finished in just a few months.

The second-floor ballroom hosted Louis Armstrong, Glenn Miller, Duke Ellington and Benny Goodman in its prime.

The building earned a spot on the National Register of Historic Places in 1986, and after a major renovation, it won the 2022 Board of Curators Historic Restoration Award from the Wisconsin Historical Society.

Today it serves as an event venue, with shops on the ground floor just steps from the public beach.

Big Foot Beach puts sand, trails and fishing right on the lake

Big Foot Beach State Park covers 271 acres on the eastern shore of Geneva Lake, named after Chief Big Foot of the Potawatomi who once led people along these shores.

The park has a sand swimming beach, wooded campsites and several miles of hiking trails. Ceylon Lagoon inside the park has fishing with an accessible pier.

In winter, the trails fill with cross-country skiers and snowshoers.

The park also connects to the Geneva Lake Shore Path, so you can pick up the full 21-mile route from here.

Free trails through oak woods, wetlands and prairie at Kishwauketoe

Kishwauketoe Nature Conservancy takes its name from the same Potawatomi word for “clear water” that the tribe gave the lake.

The 231-acre preserve in Williams Bay has more than four miles of trails through oak woods, deciduous forest, prairie and wetlands.

Boardwalks cross over marshland where you can spot more than 36 species of birds, along with deer, coyotes and foxes. Williams Bay purchased the land in 1990 to protect it from commercial development.

It’s free, and it’s open every day of the year.

Winter brings snow sculptors, ice fishing and bonfires on the beach

Lake Geneva doesn’t slow down in winter. The annual Winterfest, held in late January or early February, brings in teams from across the country to compete in America’s Snow Sculpting Invitational.

Downtown fills with an ice sculpture walk and bonfires on the beach. Nearby ski hills run 20 downhill runs.

Big Foot Beach State Park and Kishwauketoe Conservancy are open for cross-country skiing and snowshoeing. Out on the frozen lake, ice fishing draws anglers through the coldest months.

The town has about 8,277 residents, but the crowds in winter say otherwise.
