Did you know that this charming beach town has some fierce mountain bike trails!? Seabrook takes mountain biking and cycling very seriously.

If you’re serious, be sure to secure your mountain bike to your rig on your way to the beach so you can experience Seabrook’s network of trails. Feel the salty air at the bluff above the Pacific Ocean or the vibration of your handlebars as you cross the rugged forest terrain.

Seabrook’s trails and singletrack accommodate all levels. Just ask Buck from Buck’s Bikes, owner of the local cycling shop. Buck is happy to set you up with just what you need, including bikes, maps, gear – and even bear bells. Everything that fits your competitive-self level, and your family’s, too.

Seabrook has miles of off-road tracks – for enjoyment or training, and always for exhilaration. Here’s a preview:

Narnia (red) is 1.6 miles long and has a 36-foot elevation change. This is a wide singletrack that is great for all skill levels.

Mike-O-Rama (blue) is a half-mile long and has 113-foot elevation change. This trail flows very well with a good climb in both directions. The Mike-O-Rama trail has a one-of-a-kind-view halfway through your experience.

Maid Brigade (Maid Brigade yellow) is a quarter-mile long trail with a 26-foot elevation change. This is an extremely technical singletrack with tight turns, protruding roots, and shrubbery that can obstruct your path.

Wormhole (teal) is a 700-foot long trail with 45-feet of elevation drop. This trail features six berms, three rollers, and two tabletops. This track is a lot of fun for everyone. Downhill traffic only.

Zipline Trail (violet) is a quarter-mile long track with 50-feet of elevation change. The Zipline Trail is a flow trail with fun turns, a couple hips and rollers, a cedar bridge, and rock crossings.

Mill Trail (green) is a short detour following part of the promenade trail behind homes in the Mill District.

Downhill (purple) is for experienced riders only and is an extremely technical section. Downhill doesn’t have huge speeds or mastic sucks, but it’s a challenge to stay on the bike for the short trip down from Mike-O-Rama.

Access Road (brown) is a combination of Compass Street, SR 109, and old logging roads. This is the path most riders take to get to Mike-O-Rama and Narnia.

Mountain bikers who want to cross bridges can take the Narnia and Zipline trails, while bikers find jumps along the Wormhole track.

Thanks to the local community of enthusiastic riders and Evergreen Mountain Bike Alliance, Seabrook has amazing mountain-bike infrastructure, a new trail development schedule, and bike-friendly atmosphere.
