The gently rolling pathways around Whatcom Park and the creek provide some casual road running opportunities. Though mostly flat, there is one steep grade and set of stairs. They are primarily gravel, and fairly wide at most times. This isn't the place to get miles in, or a fast run, but a good spot for a recovery run or casual jog. There are multiple entry ways into Whatcom Park for runners, and the proximity to downtown makes it ideal for quick runs when you are short on time. It is popular for its access to Galbraith Mountain, as the Birch Street Trailhead for Galbraith is across Lakeway from the Upper Whatcom Falls parking lot: many people use Whatcom Falls trails as a way to bridge the gap to Galbraith. Dogs must be leashed, though there is a portion of marked unleashed area along the Waterline Trail. The park also has picnic tables, basketball/tennis courts, and restrooms. The parking is free.
Whatcom is also a fun place for families to come cruise on their bike. The trails are wide, and the bridges make scenic spots for lunch. There is only one set of stairs, but besides that, Whatcom is a great casual ride for an hour or so.
To get there, head east on Lakeway Drive from downtown Bellingham, on the east side of I-5. Take a left on Electric Avenue into the park.
