Williams Bay gets plenty of attention when the boats are in the water, the beach is busy and the sun shines upon Geneva Lake. But when the leaves turn and the lakefront gets quieter, the area becomes even more interesting.

Fall brings crisp mornings on the trails, golden color through the conservancy and evenings beneath the dome at Yerkes Observatory. Winter follows with snow-covered paths, outdoor skating, snow sculptures along the Lake Geneva waterfront and ski days that are close enough to make a Saturday on the slopes feel like a spontaneous adventure.

In other words, the list of things to do in Williams Bay, Wisconsin in the colder months does not disappear.

For us and many other Williams Bay residents, that is what makes this community such an appealing place to call home. There’s always another reason to get outside, explore the area and make plans for the upcoming weekend.

Here are some of our favorite ways to experience Williams Bay and the surrounding area from fall through winter.

What Can You Do at Yerkes Observatory in the Fall and Winter?

Although shorter days aren’t highly anticipated by many, they’re worth embracing at Yerkes Observatory.

This historic observatory is home to the world’s largest refracting telescope, and its programs give visitors a chance to experience the intricacies of the building. The Space and Spaces Tour takes you beneath the Great Refractor while exploring the architecture and people who shaped modern astronomy. For something a little more off the beaten path, the Director’s Hidden Spaces Tour takes visitors through winding staircases, corridors and rooms that are rarely accessible to the public.

Geneva Lake Conservancy Keeps Trails Open Through the Cold Months

If your ideal fall afternoon involves a trail, thermos and a little time away from everyday life, the Geneva Lake Conservancy gives you plenty of options.

The Geneva Lake Conservancy has protected thousands of acres across Walworth County through a network of properties that preserve native landscapes and open spaces. Its public preserves include Bromley Woods, Hansen Preserve, Hermansen Woods, Mill House Native Plant Preserve, Anglin Family Nature Preserve and Helen Rohner Children’s Fishing Park.

These properties give you more opportunities to experience the landscape as the season changes. One visit might mean walking beneath a canopy of fall color. A few months later, the same instinct to get outside could mean a snowy hike or skiing.

Recreation does not have to look the same every month to remain part of your routine.

Kishwauketoe Nature Conservatory in Williams Bay

Kishwauketoe Nature Conservatory gives Williams Bay its own expansive stretch of protected natural space.

This 200+ acre property has more than four miles of trails winding through prairie, wetlands and woodland. It’s open to the public year-round at no charge, and its trails can be used for a variety of recreational activities.

Winter Programming in Lake Geneva Draws Visitors from Across the Midwest

When winter settles over Lake Geneva, the calendar does not exactly go quiet.

Lake Geneva Winterfest, home to the U.S. National Snow Sculpting Championship, will fill Riviera Plaza and Flat Iron Park with free sculpture viewings, and our complete guide to Lake Geneva Winterfest covers the event from start to finish.

The holiday experience brings another uniquely local experience: the Santa Cruise. Lake Geneva Cruise Line carries passengers past shoreline holiday light displays to Santa’s hideaway.

Outdoor skating is also available close to home at the Williams Bay Ice Rink at Edgewater Park, giving another way to get you outside when the temperature falls. Additional rinks are offered at area resorts including the Abbey Resort and Lake Lawn Resort, and Big Foot Beach State Park and Grand Geneva Resort offer cross-country skiing.

For downhill skiing, you don’t have to go far either.
