About Illinois Beach State Park & North Point Marina

The destination brings together both park units, the Zion Bike Trail, South Unit campground, mapped water-trail carry-in and North Point Marina, with a representative land point chosen for local weather context.

Planning an Outing

Use the forecast to evaluate cold water, waves, rip currents, erosion, marina operations, fog, freezing spray and lake-effect snow, then confirm the operating rule for the precise part of this a dune-and-marina complex you intend to use.

Weather Tips

  • Within a dune-and-marina complex, honor posted wet-trail closures and keep bicycles off hiking-only routes.
  • Before camping at a dune-and-marina complex, confirm loops, water service and gate hours with the managing agency.
  • Use only the mapped Lake Michigan Water Trail carry-in. Open-lake paddling requires advanced skill, immersion protection and a favorable marine forecast.
