Advice on Places to Elope in Duluth

My fiance and I are from Southern Minnesota and are planning on eloping on May 30 in the Duluth area. Our immediate family is coming as well. We were thinking we would either want to be married on a beach or on an overlook on Superior Hiking Trail. I really like the idea of an overlook but I don’t want all of us to have to hike two hours to reach it. Do any of you have any ideas of which beaches would be best and where some of the best overlooks in Duluth are (preferably with a view of the water) within a reasonable walking distance? We also are looking for a plan B if it rains. Somewhere outside but with a gazebo or a nice looking building etc. Both of us want to get married outside and don’t want the rain to ruin our plans! Suggestions?
