This route was planned by komoot.
The terrain is quite hilly, featuring an extensive system of paths and wooden staircases. The main stairway alone has 302 steps, and longer routes can incorporate over 850 steps in total. The trails are generally in good condition, winding through a forested greenbelt.
The specific loop described on komoot is about 2 km (1.25 miles) and takes approximately 33 minutes to complete. However, the park offers more extended and strenuous options, including routes up to 2.5 miles with significant stair climbs, which would take considerably longer.
The difficulty ranges from easy to moderate, depending on the chosen route and pace. While the shorter loop is manageable, the numerous staircases can be challenging. Adjacent to the hillside trails, Mercerdale Hillside Park also has a flatter, paved quarter-mile loop and a children's play area, making it versatile for families.
The park is renowned for its extensive staircases, which provide an excellent cardiovascular challenge. Many locals use it for a 'Mercerdale workout,' combining a quarter-mile loop with tackling the 302-step main stairway. Longer routes can involve ascending over 850 steps.
The park is conveniently located in the heart of downtown Mercer Island. Parking is generally available in the vicinity of Mercerdale Hillside Park, often near the adjacent Mercerdale Park facilities.
As the park is situated in downtown Mercer Island, it is accessible via local public transportation routes that serve the downtown area. Check local bus schedules for the most current information on stops near the park.
Generally, dogs are allowed on trails in Mercer Island parks, but they must be kept on a leash. Please ensure you clean up after your pet to maintain the park's natural beauty.

You'll experience a verdant, forested setting with a beautiful tree canopy. The park features winding trails and a stream, with areas of big-leaf maple trees and large conifers. From nearby sections like the I-90 trail, you might even catch glimpses of the Seattle downtown skyline and Mount Rainier.
The park is beautiful year-round. Spring and fall offer pleasant temperatures and vibrant foliage. Summer is great for enjoying the shade of the tree canopy, while winter can provide a unique, quiet experience, though some trails might be damp. Always check local conditions before heading out.
The forested environment supports various local wildlife. If you're lucky, you might spot an eagle's nest within the conifer sections of the park. Keep an eye out for birds and small mammals common to the Pacific Northwest.
