Grass Lake camping options reflect the region's landscape of interconnected lakes and forest trails in southeast Michigan. Seasonal variations affect campground facilities with most rustic sites open year-round while full-service campgrounds operate May through October. Winter camping attracts a smaller but dedicated group seeking solitude on less crowded sites.
What to do
Paddling opportunities: Portage Lake offers easy lake access for kayakers and canoeists. "We had a nice paddle on the lake the morning before I left!" notes a visitor at Portage Lake Campground. The lake connects to additional waterways for extended paddling routes.
Mountain biking trails: The Waterloo-Pinckney trail system features challenging terrain for cyclists of all abilities. "The trails for Mountain Bikes that are close to the campsite are super fun!" shares a reviewer at Bruin Lake Campground. Trail difficulty varies from beginner-friendly loops to technical sections with roots and rocks.
Backcountry hiking: For overnight hiking adventures, trails connect multiple rustic camping areas. A camper at Blind Lake Rustic Campground reports, "This is a rustic campground right on beautiful blind lake. It is only accessible by foot/bike/or boat. The hike/bike is about 7 miles or 4 (depending on where you park)." Winter hiking remains popular with fewer crowds on trails.
What campers like
Lake swimming: Several campgrounds provide beach access for summer swimming. At Portage Lake, one visitor notes, "Like all the state parks this is very clean and well maintained. The lake has a little beach with sand." Water temperatures peak in July and August when swimming is most comfortable.
Stargazing opportunities: Clear nights away from urban light pollution create ideal conditions for astronomy. "We captured a sunset, some snowfall, and saw more stars than we've seen in a long time," reports a winter camper at Portage Lake Campground. Late fall through early spring offers the darkest skies.
Fishing access: Multiple lakes in the area support diverse fish populations. At Green Lake Rustic Campground, one visitor mentioned, "The campground has a small boat dock, no swimming area." Another camper noted they "had a beautiful view of the lake. There is muddy lake access on that site and I paddled from there in my kayak."
What you should know
Seasonal facility changes: Winter camping comes with reduced amenities. A visitor to Portage Lake reports, "The restrooms were closed for the season but they had a large port-a-potty... With it being off-season we didn't get to experience any amenities to speak of." Always check current facility status before visiting.
Highway noise: Several campgrounds experience traffic sounds despite their natural settings. A Hideaway RV Park visitor noted, "Biggest downfall is the never ending traffic noise from the expressway." At Green Lake, a camper shared, "You can hear highway traffic from the campground, but otherwise it was a pleasant experience."
Insects: Bug activity varies by season and location. "When we rolled up after a rain, mosquitoes were abundant near wooded areas," reports one camper. A visitor to Green Lake mentioned, "I took one star off for the dense population of ground bees that were in front of all 3 vault toilets, and along the main path."
Reservation requirements: Once-optional reservations now increasingly essential. "When I booked this camp site, I was originally looking at the Rustic camping on the app," shares a Green Lake visitor. Another notes, "While you technically don't need a reservation, we made our reservations through the DNR website about a month in advance. The campsite was listed as 'full' when we arrived."
Tips for camping with families
Playgrounds and activities: W.J. Hayes State Park Campground offers structured recreation for children. "Nice place to camp... There are fire pits and picnic tables at each site. It is usually easy to get multiple sites next to each other with reservations," notes one visitor. Another mentions, "The beach walkway is handicap accessible. There are two bathrooms throughout the loop and one at the beach. The park workers walk around and tell you about the activities they have that day."
Site selection for kids: Choose sites with open play areas but sufficient shade. A camper at Waterloo Sugarloaf Modern shares, "Spent 4 nights and 5 days camping with my husband and 2 kids. We had fun and the kids had a blast. They rode bikes around the loop and loved swimming and the playground."
Lake safety: Watch for varying lake conditions and water clarity. One visitor cautions, "Good, but not great! The campground is great, but the beach area is very mucky and dirty. Seaweed just floats around and gets tangled around your legs and arms all the time."
Tips from RVers
Site surfaces: Different campgrounds offer varying parking surfaces for RVs. "The best part of this campsite was the fact that it was paved! It was so easy setting up and tearing down. No mud, muck, or dirt," reports a winter visitor at Portage Lake. Another camper mentions, "We like to stay in the north campground because most of the sites are black topped."
Site spacing: Density varies significantly between campgrounds. At Waterloo Sugarloaf Modern, a visitor observes, "The campground has some nice full-grown trees, but isn't extremely wooded. The trees offer shade, but are spaced out enough that a group can pull their campers around for privacy." Another reports, "This campground was what we needed for squirrel hunting, however, it is very open and not very private."
Length restrictions: Larger RVs face limitations at some campgrounds. "If your longer than 40ft be aware most sites will not work for you here, they do have some but the wood line, privacy and nature is great," warns a W.J. Hayes visitor. At Waterloo Sugarloaf, one camper noted their "site was a little small for our 38foot - we had to go sideways which opened us up to other campers."
