This medium-difficulty trail offers a diverse hiking experience, combining lush forests, panoramic viewpoints, and serene creekside paths.

### Getting There To reach the trailhead, you can drive or use public transport. If driving, head towards the nearest known landmark, the town of Carson, Washington. From Carson, take the Wind River Highway north for about 15 miles until you reach the trailhead parking area. For those relying on public transport, the nearest major city is Portland, Oregon.

### Trail Overview The loop begins with the Observation Trail, which quickly immerses you in a dense forest of Douglas fir and western hemlock. The initial section is relatively gentle, allowing you to acclimate to the surroundings. After about 3 kilometers (1.9 miles), the trail starts to ascend more steeply, gaining approximately 300 meters (984 feet) in elevation. This section offers glimpses of the surrounding landscape through breaks in the trees.

### Key Landmarks and Points of Interest At around the 5-kilometer (3.1-mile) mark, you'll reach a notable viewpoint known as Observation Peak. Here, you can take a break and enjoy sweeping views of the Cascade Range, including Mount St. Helens and Mount Adams on clear days. This is a perfect spot for photography and a well-deserved rest.

Continuing on, the trail transitions into the Big Hollow Trail. This section is characterized by its rolling terrain and dense undergrowth. You'll descend gradually for the next 4 kilometers (2.5 miles), losing about 200 meters (656 feet) in elevation. Keep an eye out for local wildlife, including black-tailed deer and various bird species such as the northern spotted owl.

### Historical Significance The area around these trails has a rich history, particularly related to the indigenous tribes who have lived here for thousands of years. The trails themselves were used by Native Americans for hunting and gathering. In more recent history, the region was part of the timber industry boom in the early 20th century, and remnants of old logging operations can still be seen along the trail.

### Navigating the Trail As you approach the Dry Creek Trail, the terrain becomes more rugged. This section involves several creek crossings, so waterproof boots are advisable. The trail follows Dry Creek for about 3 kilometers (1.9 miles), with an elevation gain of approximately 200 meters (656 feet). The sound of flowing water and the lush, green surroundings make this a particularly tranquil part of the hike.
