The Mountains to Sound Greenway Trail is primarily paved and separated from motor vehicle traffic, making it ideal for road cycling. You'll find a smooth ride across urban and suburban landscapes, including sections over floating bridges and through various parks.
Yes, the main nine-mile paved section from Seattle to Bellevue is generally considered accessible for all skill levels, including beginners. It offers a relatively easy to moderate difficulty with smooth surfaces and no significant technical challenges or steep elevation gains.
The trail offers diverse scenery, from urban vistas to natural settings. You can enjoy views of downtown Seattle from Dr. Jose Rizal Park, expansive views of Lake Washington from the I-90 floating bridge, and lush wetlands in Mercer Slough Nature Park. Other sights include Elliot Bay, Lumen Field, and T-Mobile Park.
Absolutely! Keep an eye out for the unique experience of cycling across the I-90 floating bridge. You'll also pass by the View of Lake Sammamish and Mount Baker, the East Channel Bridge, and the distinctive Ventilation for the I-90 tunnel. The trail also connects to various urban green spaces like Aubrey Davis Park.
The paved sections of the trail are accessible year-round. However, for the most pleasant cycling experience, spring through fall offers the best weather. During winter, while generally maintained, you should check local conditions for ice or snow, especially on less-trafficked segments.
Yes, the trail is generally dog-friendly. However, dogs must be kept on a leash at all times, and you are responsible for cleaning up after your pet. Always check specific park rules if you venture off the main trail into connected green spaces.
No, there are no specific permits or entrance fees required to cycle the Mountains to Sound Greenway Trail itself. It's part of the larger Mountains to Sound Greenway National Heritage Area, which focuses on conservation and recreation, but direct trail access is free.
Key access points include Dr. Jose Rizal Park in Seattle, various points on Mercer Island, and the Eastgate neighborhood in Bellevue. Parking is available at several parks along the route, such as Dr. Jose Rizal Park, Enatai Beach Park, and Aubrey Davis Park. For detailed parking information, you can check resources like visitbellevuewa.com or bellevuewa.gov.
Yes, the trail is a significant regional connection and intersects with several other paths. Notably, it includes sections of the I 90 Trail and connects to paths like the East Lake Sammamish Trail and the Lake to Lake Trail, forming part of a broader network.
While the trail itself is primarily a recreational corridor, its urban and suburban nature means you'll find amenities like cafes, restaurants, and restrooms in the towns and neighborhoods it passes through, particularly in Seattle, Mercer Island, and Bellevue. It's a good idea to plan your stops in advance.
Its unique integration with the I-90 corridor, including the distinctive floating bridge section over Lake Washington, sets it apart. It's also a key part of the larger vision for the Great American Rail-Trail, aiming to connect Puget Sound to Central Washington, offering a blend of urban connectivity and natural beauty.
