Frequently Asked Questions

Where can I park to access the Green Diamond Trail?

The Green Diamond Trail is located within the Kennedy Creek Natural Area Preserve. Parking is available at the main trailhead. During November weekends, Green Diamond often opens its gate, allowing visitors to drive closer to the salmon viewing sections, which can be a significant convenience.

Are dogs allowed on the Green Diamond Trail?

Yes, dogs are generally allowed on the trail. However, it's important to keep them on a leash at all times to protect the sensitive wildlife and natural environment within the Kennedy Creek Natural Area Preserve.

What is the best time of year to hike this trail?

The trail is accessible year-round. However, the fall (especially November weekends) is particularly special due to the opportunity to observe spawning salmon up close. Fall and winter are also excellent for birdwatching, as many shorebirds visit the estuary's mudflats.

Do I need a permit or pay an entrance fee for the Kennedy Creek Natural Area Preserve?

No, there are typically no permits required or entrance fees to access the Green Diamond Trail or the Kennedy Creek Natural Area Preserve. It's a publicly accessible area, thanks to collaborative conservation efforts.

What is the terrain like on the Green Diamond Trail?

The trail offers varied terrain. Sections, particularly those leading to salmon viewing areas, are described as a 'nice walk' and are mostly ADA accessible. Other parts wander through old logging roads and can lead to a small, unmaintained, and overgrown footpath if you venture towards Kennedy Falls, offering a more rugged experience.

What kind of wildlife can I expect to see?

The Green Diamond Trail is renowned for its wildlife. In the fall, you can observe spawning salmon in Kennedy Creek. The estuary is also a prime spot for birdwatching, especially in the fall and winter when many shorebirds visit. Interpretive signs along the route provide insights into the local flora and fauna.

Is the Green Diamond Trail suitable for families with children?

Yes, many sections of the trail, especially the salmon viewing areas, are considered very family-friendly and are mostly ADA accessible, making them suitable for a wide range of visitors, including those with strollers or young children. Interpretive signs add an educational element to the experience.

Are there options for more experienced hikers on this route?

While much of the trail is a gentle walk, experienced hikers seeking a longer and potentially more challenging excursion can continue along the main logging road. This can lead to a small, unmaintained, and overgrown footpath that eventually reaches Kennedy Falls, offering a more rugged adventure.

Does the trail intersect other well-known paths?

Yes, the route also passes through sections of the S-3115, S-3120, S-3110, S-3122, and S-3140 trails.

Is the Green Diamond Trail a loop or an out-and-back route?

The Green Diamond Trail is primarily an out-and-back route. While there are various paths within the preserve, the main trail described is not a loop.

What should I wear for hiking the trail in the fall or winter?

Given the potential for rain and cooler temperatures in Washington, especially near the estuary, it's advisable to wear layers, waterproof outerwear, and sturdy, waterproof hiking boots. Binoculars are also recommended for birdwatching during these seasons.
