This is a great place to take a long walk, run, or go biking. You can get some great photos along the water and it's a nice long paved trail that any age group can do easily. People are pretty nice and friends like to get together for a walk to downtown.
The views are great and it's long but easy. Did I mention that it's free? What's better than that? You can rent a bike at one of the many shops downtown and take your camera with you for some great shots. Take some food out with you for a picnic.
Keep your eyes open for wildlife. Not usually an issue if there are a lot of people, but the seagulls can get a bit pushy. The moose too!!
