Lord Hill Regional Park Professional Review and Guide
"Located south of the Old Monroe–Snohomish Road and north of the Snohomish River, Lord Hill Regional Park is a relatively unknown circuit of intermediate trails. The 1,300-acre park is crisscrossed with more than 10 miles of hiking, biking, and equestrian trails. Most of them are old logging roads wide enough for as many as four bikes to ride comfortably side by side. Unfortunately, not all of them are open to mountain biking, and some of the bike trails are closed during winter to protect the trail surface.
The majority of trails in Lord Hill Park are veiled by a thick canopy forest that keeps them moist and tacky, providing slot car–like traction. However, after a short burst of rain, the trails can become wet and muddy even mid- to late summer. Please pay attention to seasonal closures (November to April) of various trails. The 3 or 4 miles of singletrack reserved, although not exclusively, for fat-tire folks are challenging due to rocks, roots, and routinely slippery conditions. The lack of serious climbing makes the ride ideal for lower intermediate cyclists who want to improve their skills. Trail surface: Maintained gravel trails; hard-pack dirt with roughly a mile of technical riding over roots, rocks, and slippery obstacles."
