The westernmost end of the western half of the Whatcom Creek Trail is Maritime Heritage Park, which has a small trail system all on its own. One of its highlights is the Whatcom Creek Fish Ladder — in the fall, when salmon are running, you'll likely find other folks around to watch the bounding fish. The park also features the Maritime Heritage Center, amphitheater, picnic tables, benches and interpretive displays.
If you head out of the park that way — past the fish ladder, up the stairs to the bridge — you'll start along the Whatcom Creek Trail. From here, the trail follows Whatcom Creek, crossing a few roads along the way. Be careful as you cross the street as these are marked but non-lighted mid-block crosswalks.
Note that the section of the Whatcom Creek Trail between Ellis St and I-5 is the sidewalk along the road — east on Kansas St, then east on Meador Ave to I-5.
