There’s a specific feeling the Chain gets in mid-May. The boats are coming off the lifts. The marinas smell like two-stroke and new season. The parking lots at the state park fill up a little earlier every weekend.
Summer hasn’t started. But everyone around here knows it’s close.
Here’s what’s actually happening before Memorial Day flips the switch.
The Walleye Opener (May 15)
It’s not a ticketed event. There’s no stage or food trucks. But if you grew up here, you know the walleye opener is a happening. Every year on May 15, the closed season lifts and half the fishermen in Lake County are on the water at first light.
Chain O’Lakes State Park has boat launches that’ll be busy early. Pistakee is the traditional walleye water, and the channels around Channel Lake are worth the run. If you’ve never done it, go once. It’s a cold thermos and a dark ramp and a lot of people who are exactly where they want to be.
IHSA Bass Fishing Tournament
High school bass fishing is one of those things people outside the area don’t know about until they see it. The Illinois High School Association runs a state tournament series, and Fox Chain’s south section is a regular venue for sectional competition.
Multiple high school teams fish it — casting for largemouth on the same water their parents and grandparents fished. It’s legitimately competitive, and worth watching if you’re already out on a weekend morning. Check IHSA.org for current schedule details.
Walleye Tournament Circuit
The competitive walleye season is already running. The Fox Chain circuit draws boats from across the Midwest, with tournaments typically launching from Port of Blarney and Chain O’Lakes State Park. Entry fees run $50–100 per team and events fill fast. Triangle Bait in Antioch keeps a current schedule behind the counter if you want the specifics.
Chain O’Lakes State Park Spring Programs
The state park is running its spring nature programming through May. Guided hikes, fishing-opener events, wildlife viewing. If you have kids who’ve never held a rod, the park is a better first fishing experience than a crowded Saturday at the public ramp. Less noise, better shore access, staff who know what’s in the water.
Call 847-587-5512 for current programming, or check in at the visitor center. They’ll tell you what’s running this weekend.
Memorial Day Weekend: The Real Opener
May 26 weekend is when it all happens at once. Every marina on the Chain does some version of a kickoff. Docks get busy. The no-wake zones start actually mattering again. The food spots near the water go from quiet weekday lunch to forty-five-minute wait without much warning.
It’s not a single event so much as the whole area deciding simultaneously that summer is on. The lakefront in Fox Lake will have people on it by eight in the morning. Boats that have been sitting in storage since October will be making their shakedown runs.
If you’re a local, get your errands done by Friday afternoon. If you’re coming up from the city for the first time this year, build in more time than you think, and don’t assume parking near the water is easy.
Friday Night Live: Coming Late May
Fox Lake’s summer concert series at Lakefront Park kicks off in late May and runs every Friday through August. The format is a farmers market from 4 to 7, then live music from 7 to 9. Free admission. Food trucks, local vendors, regional bands.
The opening night usually draws a good crowd of people who’ve been waiting since September for an excuse to stand by the water with something cold in their hand. Check the Village of Fox Lake website for confirmed dates as they’re announced.
Looking Ahead: What’s Coming in June
The calendar gets much busier from here. Wauconda Fest runs in late June at Cook Park, drawing tens of thousands over four days. Taste of Grayslake is the same weekend. The Long Grove Strawberry Festival is mid-month. And Celebrate Fox Lake — the village’s Fourth of July weekend festival with fireworks over the water — is the single biggest event of the summer on the Chain.

If You’re Coming Up for the First Time
Mid-May is genuinely a good time to visit. Crowds are lighter than June. Temperatures are reasonable. The fish are biting. The marinas have availability.
Chain O’Lakes State Park is the easiest entry point — multiple boat launches, shore fishing access, camping, and trails. No prior local knowledge required.
The season is starting. The Chain is ready.
