Lynden / Whatcom
Confirmed, but horseback riding is April-October only; no riding Friday-Sunday from April through September. The horse-trailer lot closes November-March.
Ferndale / Whatcom
The current WDFW Lake Terrell page lists trails but does not explicitly authorize horseback riding. Past planning material mentions riders, so call the wildlife-area manager before hauling, especially during pheasant season.
Point Roberts / Whatcom

Anacortes / Skagit
Current city material confirms a multi-use trail system but does not clearly identify today's horse-permitted routes. Keep this as a lead until Anacortes Parks confirms the route and trailer staging.
Sedro-Woolley to Concrete / Skagit
A current official or land-manager source still lists this as a horse-access destination. Recheck day-of-trip alerts before hauling.
Hamilton / Skagit
Confirmed horse-focused trail system. DNR lists a Harry Osborne State Forest seasonal closure for Dec. 1, 2026-Feb. 28, 2027; camping at the trailhead remains prohibited.
Alger / Skagit
No current land-manager source was found that confirms legal horse routes or trailer staging. This remains a community lead, not a ready-to-haul destination.
Mount Vernon / Skagit
Confirmed, but Walker Valley is primarily an ORV area. Intermittent Peter Burns Road work may close sections, so this remains a high-conflict choice.
Mt. Baker Highway / Whatcom
Confirmed stock trail, open to stock July 1-Oct. 31. Check current Forest Service fire and road alerts before departure.
Mt. Baker Highway / Whatcom
Confirmed stock trail, open to stock July 1-Oct. 31. Check Hannegan Road and trailhead alerts before departure.
Mt. Baker Highway / Whatcom
Confirmed stock trail, open to stock July 1-Oct. 31. The maintained route ends before the scramble section.
Baker Lake / Skagit
Confirmed stock access and stock parking, generally July 1-Oct. 31. The trailhead is heavily used and current road/bridge alerts still need a trip-day check.
Mt. Baker NRA / Skagit
Confirmed stock trail, open to stock July 1-Oct. 31. Remote wilderness conditions warrant a ranger-district check before hauling.
Middle Fork Nooksack / Skagit
Confirmed stock trail July 1-Oct. 31, but south access is currently inaccessible from Pioneer Camp due to a washout. North access requires an unbridged Middle Fork Nooksack crossing.
Baker Lake / Skagit
The current Forest Service directory again lists Baker Lake Trail and its south trailhead for horse riding. The older bridge-decking stock closure could not be found on the current page, so call the Mt. Baker Ranger District before hauling.
Central Whidbey / Island
Confirmed on Island County's current map. Horses remain prohibited on adjoining Fort Ebey State Park trails; stay inside the county trail system.

Confirmed equestrian park. Red Barn Trail remains closed to all users while repairs are planned, and the 2025 map should be used.

Easton / Kittitas
Lake Easton State Park is open, but its current official page does not list horse access or a horse camp. The nearby Palouse to Cascades Trail allows horses; use a verified equestrian camping base instead.

A NOTE BEFORE YOU HAUL
Forest roads, bridges, fires, logging, ferry service, tides, and winter damage can change horse access quickly. Treat this as your planning base, then open the official source and verify conditions before every trip.
Map pins are planning locations. Use the directions link and the land manager’s trailhead guidance for your final trailer route.
