Big Bay State Park

The ferry slips away from Bayfield and you watch the mainland recede. Twenty minutes later, you step onto Madeline Island—the largest of the 22 Apostle Islands and the only one where you can camp in a state park, swim on a mile-long Lake Superior beach, and hike through old-growth forest where bald eagles nest in ancient trees. This is Big Bay State Park, and getting here is half the adventure.

Welcome to Big Bay State Park, 2,350 acres of Lake Superior wilderness on an island that feels worlds away from mainland Wisconsin. Four miles of rugged lakeshore, a 1.5-mile sandy barrier beach, mystical sphagnum bogs, and the pristine Big Bay Lagoon combine to create one of Wisconsin’s most unique outdoor destinations. Whether you’re beachcombing for agates, paddling calm lagoon waters, hiking sandstone bluff trails, or camping within earshot of Lake Superior’s waves, Big Bay delivers an island escape unlike anything else in the state.

What Makes Big Bay Legendary

Barrier Beach

The Barrier Beach is Big Bay’s crown jewel—a 1.5-mile stretch of sand along the Lake Superior shore. Unlike the rocky beaches typical of Superior, this rare sandy expanse is perfect for:

• 🏊 Swimming: Lake Superior waters (cold but refreshing!)
• 💎 Agate hunting: Search for Lake Superior agates
• 🏄 Paddling: Launch kayaks and paddleboards
• 🌅 Sunset watching: West-facing views over the lake

Big Bay Lagoon

The Big Bay Lagoon is a protected body of water on the park’s interior—calmer than Lake Superior and excellent for paddling. A wildlife observation deck on the east shore offers prime viewing for:

• 🦅 Bald eagles
• 🦆 Waterfowl
• 🦫 Beaver
• 🦌 White-tailed deer
