Walked the South Bay trail north from Taylor Dock all the way up to Maritime Heritage Park Tuesday morning. Total distance round trip to the park and back is a shade over 5 miles and less than 100' vertical. No trail issues, but do pay attention when crossing the railroad tracks at Boulevard Park due to the fairly heavy train traffic on the main line there - the relatively new pedestrian signals are a nice addition there.
The views of Bellingham Bay are even better this time of the year with no leaves on the trees. The more urban north end is also an interesting landscape with port activities, Bellingham waterfront redevelopment work, boats, etc. Don't miss some interesting artwork on buildings and if you go soon there are some neat, spontaneous holiday decorations along the trail as well if you look closely. An easy to get to walk with nice forest and water views and lots to see.
