When to go
Best season
September, October
Best time
Morning, Mid-day, Late afternoon
Fall color usually peaks on the lakeshore here in late-September to mid-October.
The angle of lighting to see the color on Lake Superior is best morning through mid-day. Also, this is a long hike, and you may not want to be at this spot in late-afternoon in the fall, as you might have to hike back in the dark.
Field tips
Shooting wide with an aperture of f/8 or greater will keep the cliff you're standing on, Lake Superior, and the Grand Portal Point arch in the distance, all in focus.
As you set up your composition, aim to put the foreground sandstone in the bottom third, and the horizon as the top third of your image.
Be sure to turn your polarizer so that you can best see the fall color and the water color.
If you want a cruise boat in your photo for perspective, just hang around for a bit. If the water on the lake isn't too choppy, cruises come by regularly.
