I'd recommend the Copper Harbor Trails especially in the spring and fall when it's nice and cool and the leaves are down so the views are good. There are pretty many water crossings to drink and wallow in when it's hot. Trail dogs aren't big fans of all the bridges there, since our paws can get stuck in the cracks, but I usually run around them anyway. My pack says the bridges are a hoot.
These trails rock. They're my favorite!
