Timothy Lake Loop, Portland, Oregon - mostly flat, stroll around the Lake with breathtaking views of Mt. Hood and beautiful forests. Be sure to get a look at Little Crater Lake, a small artesian pool near the trailhead.
On next visit to Oregon Coast: Oswald West, between Manzanita and Cannon Beach. You are required to walk mile through an ancient forest, along a river path, before you reach the beach. If you are a fan of mossy tree stumps, this is the place to go.
