Looking to take a weekend trip to the Apostle Islands in July, my adult daughter and I. We'd arrive Friday night, leave Sunday afternoon. Just looking to take in the beauty, no kayaking or canoeing for us. Totally roughing it - just want an adventure. No hotel, no restaurant, just want to see the beauty. What is a must-see? Thinking of taking the car ferry to Madeline island. Then what? Would love to hear your recommendations!
