As the name suggests, the Railroad Trail was constructed on the bed of an old railroad. It is made of crushed limestone and is a great traffic free alternative to Barkley Boulevard.

Nestled along the Whatcom Creek Greenway, Derby Pond is a true angler's paradise. Spanning over 23 acres, it is home to abundant largemouth bass and other fish species, making it a popular destination for fishing enthusiasts. It serves as a vital trout-raising location, contributing to stocking numerous lakes, streams, and ponds in Washington state. Whether a quick stop or a leisurely break, this tranquil haven offers the perfect spot to have lunch during a long day of riding.

From the bridge here, you pass over Lake Whatcom and can enjoy the views of the open water on one side, and the Whatcom creek that feeds Derby Pond on the other!

Hikers can head north along Whatcom Creek to reach the fish hatchery. Trout are raised here to feed Washington state lakes, streams and ponds (including nearby Derby Pond). Watch for ducks at the peaceful pond before continuing north to check out the old railroad trestle.
