What to See at the Apostle Islands

A what-to-see guide to Wisconsin's 21 islands on Lake Superior.

By Chris Hayworth, Nestward

Apostle Islands isn't a drive-up park. It's 21 islands and a 12-mile mainland shoreline along Lake Superior at the northern tip of Wisconsin's Bayfield Peninsula, and most of the good stuff is reached by boat, kayak, or a hike to the water's edge. Set your expectations right and it's one of the most rewarding lakeshores in the system; show up expecting overlooks off the highway and you'll wonder where the park is.

The mainland sea caves

The signature sight is the red sandstone sea caves, where Lake Superior has carved arches, chambers, and honeycombed cliffs into the shoreline. In summer you reach them by kayak or on a narrated boat tour out of Bayfield; the cliff-top Lakeshore Trail above them gives you the long views without getting in a boat. In a hard winter (and only when the park officially declares the ice safe) people walk out across the frozen lake to see the caves draped in icicles. That ice window is never guaranteed and has gone years without opening, so don't build a trip around it.

Lighthouses and the islands

The park holds the largest collection of lighthouses in the National Park System, and they're a big part of why people come. Raspberry Island Lighthouse is the showpiece, a restored keeper's complex you can tour (often with costumed guides), and it reflects the sunset beautifully off the water. To get onto the islands you have a few options:

• Apostle Islands Cruises from Bayfield runs narrated tours and lighthouse trips, the easiest way to see several islands without your own boat.
• Sea kayaking is the classic way to reach the caves and quieter islands, but Lake Superior is cold and moody; go with a guide unless you're genuinely experienced.
• Your own boat opens up the whole archipelago, with docks and anchorages scattered across the islands.

Beaches and island hikes

Stockton Island is the most popular island destination, and Julian Bay there is a long sand beach worth the trip, including the "singing sands" that squeak underfoot. Stockton has hiking trails, a campground, and ranger programs in season, making it a good first island if you only do one. Across the islands you'll find sandy beaches, rocky shorelines, old-growth forest, and quiet coves that feel a long way from anywhere. Swimming is possible in mid-to-late summer, but Lake Superior stays cold. Water temperatures sit in the 40s in May and June and only warm modestly after.

Bayfield and the visitor center

Bayfield is the gateway town and the practical hub: the park headquarters and main visitor center sit right in town at 415 Washington Avenue, and it's where the boat tours, outfitters, and most lodging are based. Start here to check conditions, grab the Junior Ranger booklet for kids, and confirm what's actually running that day. The park itself is open 24/7 year-round, but visitor centers are summer-only with variable hours, and the islands are a seasonal proposition.

Know before you go

• You need a plan to reach the islands. Decide in advance whether you're cruising, kayaking, or bringing a boat. There's no shuttle that just shows up.
• Respect the lake. Lake Superior is famous for fog, sudden squalls, and rough seas. Check the marine forecast and assume conditions can flip fast.
• This is Ojibwe homeland. The islands lie within the ancestral homeland of the Ojibwe people, worth knowing as you visit.
• Best stretch is roughly June through September, when tours run, water is (relatively) swimmable, and the visitor centers are staffed.
