Are there any scenic viewpoints I shouldn't miss on either route?

Absolutely, there are several breathtaking scenic viewpoints that you shouldn't miss along both routes. If you’re traveling along the coastal highway, be sure to stop at the iconic Cape Lookout State Park. The sweeping views of the Pacific Ocean framed by lush forests are nothing short of spectacular. The drive to the viewpoint itself offers glimpses of rugged cliffs and sandy beaches, but the moment you step onto the viewpoint, you'll be treated to a panorama that beautifully captures the essence of the Oregon coast. It's an ideal spot for whale watching during migration seasons, so keep your eyes peeled for the majestic creatures.

On the inland route, consider visiting the Columbia River Gorge. The viewpoints here are equally stunning, with highlights like the Vista House at Crown Point, which provides a commanding view of the river and the surrounding mountains. The area is dotted with waterfalls, and a short hike to Multnomah Falls is absolutely worth the effort. The sight of the water cascading down the cliffs is a photographer's dream. Each viewpoint along this route offers a unique perspective of the landscape, making it a delightful journey for nature lovers and adventure seekers alike. Whether you choose the coastal or inland route, the scenic viewpoints will undoubtedly leave you with unforgettable memories.
