Paddle the Red Cathedrals: Half-Day Kayak to the Mainland Sea Caves
Two hours on Superior, a billion years in the making
Lake Superior exhales at Meyers Beach. The wind brushes the stairway as you shoulder a tandem kayak and descend toward the launch, and the lake—broad-shouldered and cool-headed—seems to nod you in. Out beyond the cobble, the Mainland Sea Caves scallop the shoreline, a lace of sandstone chambers and arches carved by storms and time. This half-day paddle wastes no motions: a 30-minute beach tutorial, a one-mile approach, and then two hours weaving through chambers where Superior pushes, whispers, and, sometimes, roars.
Trail Wisdom
Aim for morning departures
Winds and waves typically build through the day on Superior; earlier tours often mean calmer water and better cave access.
Read the swell before you enter
Pause at each cave mouth to watch a full set of waves so you can time your glide on the quieter beat.
Dress for cold water, not air
Even on hot days, Superior is chilly—thin, quick-dry layers under a wetsuit keep you warm without bulk.
Secure your valuables
Use the provided dry bag and a phone leash; if it drops here, Superior keeps it.

Conservation Note
You’re paddling within Apostle Islands National Lakeshore—keep distance from nesting birds, avoid touching fragile cave walls, and pack out everything you bring.
The red sandstone caves belong to the Devils Island Formation of the Bayfield Group, shaped over roughly a billion years and continually reworked by Lake Superior’s freeze–thaw cycles and storm waves.
Seasonal Guide
spring
Best for: Fewer crowds, Crisp clarity after ice-out
Challenges: Cold water, Changeable weather
Spring brings clear water and quiet days, but wetsuits are usually required and tours are weather-dependent.
summer
Best for: Warmer air temps, Consistent tour openings
Challenges: Afternoon winds, Parking fills early
Prime season for paddling the caves—book ahead, go early, and plan for sun plus a sudden breeze.
fall
Best for: Stable conditions, Brilliant shoreline color
Challenges: Cooling water, Shorter daylight
September often offers glassy mornings and vivid maples; bring an extra layer and watch the forecast.
winter
Best for: Shoreline hikes, Rare ice-cave events
Challenges: Tours typically paused, Severe conditions
Guided paddling generally shuts down; occasionally the park opens ice-cave walks when conditions are safe, but it’s rare and unpredictable.
Photographer's Notes
What to Bring
Windproof shellEssential
Superior’s breeze can chill quickly; a light shell blocks wind between paddling intervals.
Neoprene water shoes or bootiesEssential
Protects your feet on the cobble beach and keeps traction while launching and landing.
Sunglasses with retainer
Glare can be intense near the caves; a strap prevents accidental donations to the lake.
Light neoprene gloves
Keeps hands warm when air is cool and spray is frequent without sacrificing paddle feel.
Common Questions
How far is the paddle to the Mainland Sea Caves?
The approach from Meyers Beach is roughly one mile to the first caves, followed by about two hours exploring the cliffline.

Lake Superior calls the shots. Tours may be shortened or canceled if wind or waves are unsafe. You’ll be rescheduled or refunded if the trip can’t go.
What to Pack
Reusable water bottle to stay hydrated; windproof shell to cut Superior’s breeze; neoprene water shoes for traction on the cobble; sunglasses with retainer to manage glare and avoid losing them to the lake.
