Allegan County’s Favorite Summer Swimming Spot
Littlejohn Lake County Park has been a summer institution for Allegan County families for decades. Set on a clear inland lake with a sandy swimming beach, shaded picnic areas, and a comfortable mix of amenities that work well for groups of all sizes, it offers the kind of unpretentious, genuinely enjoyable day out that was always the best part of summer — before everything needed to be curated or photogenic to be worth doing.
At 113 acres, the park is substantial enough to offer real variety without being so large that it requires a half-day of logistics to navigate. The lake is the centerpiece, but the woods behind it, the volleyball courts, the playground, and the pavilions for larger gatherings give the park dimension that keeps it useful well beyond just a beach day.
Location and Getting There
Littlejohn Lake County Park is located at 3540 113th Avenue, Allegan, MI 49010. From downtown Allegan, head north on Hubbard Street, continuing north as the road transitions, then west on 113th Avenue — the park entrance is clearly marked along the south side of the road. The drive from downtown Allegan takes approximately 10 to 15 minutes.
From our Pullman office, the trip runs roughly 25 minutes. Head north on the Blue Star Highway through Fennville, then east on 108th Avenue or 113th Avenue toward the park. The park sits in a rural township setting with surrounding farmland and woodlots — an environment that reinforces the “away from it all” character of the visit even though the city of Allegan is just a few miles away.
Parking is available inside the park entrance. A county park pass is required for vehicle entry — Allegan County residents can purchase an annual pass, and daily passes are available for non-residents. Fees are modest; check the Allegan County Parks website for current rates and pass purchase options before your first visit.
The Lake and Swimming Area
Littlejohn Lake is a clear inland lake typical of Allegan County’s glacially formed terrain — a moderate-sized body of water with a sandy bottom in the swimming zone, gradual depth progression, and good water quality maintained through the county parks management program. The designated swimming area is buoyed and monitored by lifeguards during the summer season.
The beach itself is modest in length but functional — enough sandy shoreline for spreading out towels, digging in sand, and wading without feeling crowded on typical weekdays. On busy summer weekends, the beach fills to capacity and arrives there earlier than most visitors expect. The water temperature in the lake tracks with air temperature more responsively than Lake Michigan, warming faster in spring and reaching comfortable swimming temperatures by late May in most years.
The swimming area is generally appropriate for young children due to the gradual depth progression. Non-motorized watercraft (kayaks, canoes, paddleboards) can be launched from the designated area and used on the lake outside the buoyed swimming zone, though motorized boats are restricted to keep the swimming area safe and the lake environment quiet.
Trails, Pavilions, and Recreation Areas
Beyond the swimming beach, the 113 acres of the park accommodate multiple recreation zones that extend the visit well beyond the water’s edge.
Hiking trails wind through the wooded sections of the park, passing through mixed hardwood forest of oak, maple, and beech that provides good shade during summer months and excellent fall color in October. Trail surfaces are natural (dirt and wood chip) rather than paved, making them appropriate for casual hiking but worth checking after wet periods.
Playground equipment serves younger visitors, and a volleyball court near the picnic area accommodates casual games with no reservation required. Disc golf enthusiasts will find the sport increasingly popular in the park’s open areas — check with park staff for current layout details.
Several pavilions are available for group reservations, making Littlejohn Lake County Park a regular venue for family reunions, company outings, and community events through summer and early fall. Reservations for pavilions are managed through Allegan County Parks; advance booking is recommended for summer weekends.
Best Time to Visit
The park is open seasonally, with full services operating Memorial Day weekend through Labor Day. For swimming, the warmest and most reliably comfortable conditions run from late June through August. The peak crowd period is July — arriving before 10 a.m. on summer weekends is the standard local advice for securing a good section of beach and a picnic table in reasonable proximity to the water.
Late May and early September offer the swimming beach with considerably fewer people. The water is cooler in May, but by September it retains most of the summer warmth and the crowds have largely departed for the school year. Fall trail use extends the park’s season without beach amenities for those who want the wooded setting without the summer intensity.
Winter access is informal, and the park’s trail network is occasionally used for snowshoeing after significant lake effect events — though the park is not groomed or maintained for winter recreation.
Moisture, Woodland, and Water: The Roofing Picture in Allegan County
A park like Littlejohn Lake sits at an interesting intersection of Allegan County’s landscape — shoreline exposure on the lake side, woodland coverage on the interior, and the agricultural fields that define the broader township landscape all around. The homes and properties surrounding a park like this experience the full range of moisture and weather challenges that make Allegan County roofing more complex than many homeowners initially expect.
Lake-adjacent properties deal with higher ambient humidity and the biological growth that accompanies it — moss, algae, lichen — particularly on north-facing or shaded roof planes. Wooded properties contend with debris accumulation, persistent shade that prevents proper drying after rain events, and the physical risk of falling branches during ice storms and high-wind events that Allegan County sees annually.
Properties in the open agricultural sections between woodlots experience more aggressive wind exposure without the tree barriers that slow it down — the same conditions that affect the Kal-Haven Trail corridor to the south. Each of these settings puts different stresses on roofing systems, and understanding which applies to your home shapes the right maintenance and replacement approach.
Our team works across Allegan County’s varied property types, from wooded lakeshore parcels to open township farmsteads. Whether it’s a roof inspection after a storm or addressing the accumulated effects of a decade of Michigan winters, we’re familiar with what this landscape does to roofing materials.
