An illuminated riverside trail, a self-guided historic tour through downtown, and flowers along the streets: Castle Rock offers different ways to experience the town and its surroundings. To help with your planning, consider the differences between the trails, events, and regional natural attractions.
River Trail and Bike Park
The 1.7-mile Riverfront Trail is an illuminated, paved, multi-use trail. It runs north from Lion’s Pride Park to the Castle Rock Sports Complex. Sections of the trail lie on both sides of the Cowlitz River. Check local conditions before your visit.
The Bike Skills Park has a different focus: its several skills and practice features are designed for everyone from beginners to experienced cyclists. Use is restricted to bicycles and trail bikes. When choosing between the two, the Riverfront Trail offers a longer route, while the Bike Skills Park focuses on practicing riding skills.
Historic Downtown, Flowers, and Events
Historic downtown Castle Rock offers a wide selection of shops, antique stores, restaurants, and accommodations. Individual businesses’ offerings may change. The Castle Rock Walk is a self-guided historic and floral tour through downtown. If you plan to take it, confirm route details locally.
The town’s floral program also contributes to its character: Since 2011, under the direction of volunteers, it has decorated the streets with abundant hanging baskets, planters outside businesses, and garden beds. The program is award-winning; seasonal displays may vary.
Events also take place at different times of year. The Castle Rock Fair is held annually in July, and the Festival of Lights is held annually in December. Specific dates may vary. For 2026, the Castle Rock Sunday Market is scheduled, weather permitting, from May through October on Sundays from 11 a.m. to 3 p.m. at Haircut Express in Castle Rock. Offerings include food, produce, handmade goods, plants, and antiques.
Regional Natural Attractions
At Seaquest State Park, a pedestrian tunnel connects the park with the Mount St. Helens Interpretive Center and Silver Lake. The park has more than 12 miles of hiking trails; trail conditions may change seasonally. Silver Lake is a shallow wetland lake that is home to numerous bird and wildlife species. The trails and the lake showcase different aspects of this natural area.
At the Mount St. Helens Visitor Center, you can explore Silver Lake on a 0.6-mile trail with boardwalks over the wetland. At different times of year, you can observe aquatic plants and migratory birds there. This shorter route offers a different time commitment than the extensive trails in Seaquest State Park.
Route and Water Access
Castle Rock is a gateway to the northern entrance of Mount St. Helens via State Route 504. Conditions along the route may vary, so factor this into your plans. On the Cowlitz River, Al Helenberg Memorial Boat Launch provides access for motorized and non-motorized boats, as well as kayaks. Parking is available. Along with the trails, this offers options for spending time by the water.
