Have a good light for those dark sections of the trail when riding at night. Pedestrians often do not have any reflective gear, so be careful

This 19.1-acre park is a wide, grassy open space with plenty of pathways for a great run. There is a big hill on the grounds that is popular for flying kites, a playground, a sundial, and a gorgeous view of Seattle. The park gets its name due to the ruins of a former coal gasification plant, preserved behind a fenced area.

Meandering climbing street that connects Lake Washington to the Arboretum - Definitely a beautiful stretch of the Lake Washington loop.

This is the best path between Lake Washington and the Cross-Kirkland Corridor.

This park was remodeled in 2022 and is by far the best place to stop for a lunch break along the Burke Gilman Trail. Nice job, Kenmore City Council! Summertime kayak rentals and concession stand.
