4. Admire the view from the northwestern-most point in the contiguous United States.

The landscape of Cape Flattery can only be described as enchanting. It showcases some of the most beautiful of western Washington's landscape: deep coves, hardwood forests, and breathtaking coastal views. Plus, the lookout point can be reached via a relatively easy 3/4-mile boardwalk trail. From this unique vantage point you'll be able to spot Tatoosh Island in the distance.

5. Marvel at fossilized wood at Ginko Petrified Forest.

Few people realize that central Washington is actually home to one of the largest petrified forests in the world. Situated along the Columbia River, this fascinating landmark is certainly worth a visit. It was 1932 when evidence of petrified ginkgo and sequoia trees was discovered here. These fossils, which resemble rocks, date back over 15 million years! Along with interpretive signs, you'll also discover plenty of information in the visitor's center. This landmark is situated inside the Wanapum Recreation Area, at 4511 Huntzinger Rd, Vantage, WA 98950.

6. Admire the pristine waters of Blue Lake in North Cascades Park.

No trip to Washington is complete without some sort of mountain adventure. North Cascades National Park offers glaciers, alpine lakes, and endless forests to explore. While any hike in this famed national park promises to be enchanting, few can beat Blue Lake Trail. This moderately difficult 5.3 mile trek leads hikers to an exquisite lake whose water really is emerald-colored.

7. Embark on a rainforest adventure.

Tucked away in Olympic National Park awaits a landscape unlike any other in the U.S. The Hoh Rainforest receives between 12 - 14 feet of rainfall annually. This heavy amount of moisture results in lush, dense forests where mosses and ferns grow rampant. The Hoh features many trails that will showcase the rainforest. The Hall of Mosses, for example, is a relatively easy 1-mile loop that's situated near the visitor's center.

8. Enjoy an epic waterfall hike.

The breathtaking Falls Creek Falls can be found in Gifford Pinchot National Forest. It's accessible via a 5-mile loop trail ranked as moderate in difficulty. This beloved trail will take you over a suspension bridge, past picturesque creeks, and through lovely old-growth forests. Finally, you'll reach the main attraction: a stunningly beautiful waterfall that will stop you in your tracks. The trail offers plenty of shorter spur trails so you can enjoy the falls from different vantage points.
