What campers say
Thompson / Grand River Valley KOA Holiday offers family-focused amenities — ponds with inflatables, a pool, playground, fishing, kids’ activities and a stocked camp store. Staff are often described as friendly and responsive, and many sites provide ample space for larger rigs. Reviewers note tradeoffs: the access and internal roads are gravel and can be dusty, landscaping and site upkeep are inconsistent, and there are mixed reports about bathhouse/pool cleanliness and occasional water outages. Management and seasonal dynamics draw varied feedback. Overall, it’s an activity-rich option for families willing to accept some variability in maintenance.
