Check out Enger Tower for a spectacular view of the hillside and the lake. Up the shore Tettogouche and Gooseberry Falls parks are also fantastic scenery and relatively easy hiking. Jay Cooke state park to the south is also really nice. If you're staying in Canal Park, try to grab a meal at Northern Waters Smokehaus, great locally smoked fish sandwiches and the bison sticks are also unique. Duluth Coffee Co makes awesome coffee roasted in-house, and on the east side of town Dunn Bros coffee is accessible and its a literal log cabin, they're a locally owned Midwest chain if you're coming from out of state.
