just Choose Your Spot, unpack, & enjoy.

  • Lakefront Sites

    Front-row access to Grand Lake living. Wake to open water views, morning light across the lake, and evenings that slow down just right. Lakefront Sites place you directly on the shoreline — perfect for boat owners, fishers, and anyone who wants the lake to be part of everyday life.

    • Direct lake access

    • 30/50-amp electric, with a majority of premium sites offering full hookups

    • Extra space for patios, docks, and lake-life setups

    RESERVE YOUR SITE ▸

  • Interior Sites

    Central, connected, and close to everything. Interior Sites keep you at the heart of Kozy Kampground. You’ll be steps away from the pool, playground, events, and gathering spaces — ideal for families and campers who enjoy being part of the action while still close to the water.

    • 30/50-amp electric, with a majority of premium sites offering full hookups

    • Walkable access to amenities, activities, and community events

    • Excellent value with a central campground location

  • Canal Sites

    • Canal-side access connecting your site directly to the lake

    • 30/50-amp electric, with a majority of premium sites offering full hookups

    • Closer proximity to amenities and events than open lakefront sites
