Coa Valley lies in northeastern Portugal near the Douro River, in a landscape shaped by steep hills, schist cliffs, vineyards, olive groves, and almond trees. The area is best known for its open-air prehistoric rock engravings, spread across the banks of the Coa River and protected as a UNESCO World Heritage Site.

Pictured Rocks National Lakeshore stretches along more than 40 miles of Lake Superior shoreline in Michigan’s Upper Peninsula, between Munising and Grand Marais. It is known for sandstone cliffs, forested hills, beaches, waterfalls, and clear freshwater coves.

Petersburg, Alaska sits on Mitkof Island in Southeast Alaska, where ocean channels and forested mountains shape everyday life. The town looks out over the Wrangell Narrows, a narrow water route so winding that boats often follow a carefully timed path to pass through. Wooden docks line the waterfront, and fishing boats are a constant sight, reflecting how closely the town is tied to the sea and seasonal harvests.
