Trail Overview

Illabot Mainline is a 23-mile out-and-back gravel road located 10 minutes north of Darrington and dead-ends at several hiking trails. This trail is open to all vehicles for the first 6 miles before becoming heavily rutted and brushy; some 2WD and full-size vehicles may have a hard time past this point. Illabot features many stopping points, including views of eastern Skagit Valley and a waterfall. The Illabot Mainline passes in and out of Mount Baker National Forest and Sierra Pacific Land and Timber Company property, however, public use is allowed with some restrictions per spi-ind.com. The Illabot Mainline is an excellent trail for those looking to get their feet wet in some light offroading while getting some great views! As of 4/15/24, the Illabot Mainline is blocked at 9 miles in by significant windfall.

Trail was in good shape though there was at least one dump site, a few abandoned wrecks and some target practice trash in several areas. Most of the road was smooth though keep on the lookout for potholes in the flats. There was a brush clearing operation going on today that cleared all but the last mile or so to the split to the Slide Lake trailhead and at least one side road. The split up to thw summit was a but too overgrown for my taste today and the rest of the road to the Slide Lake trailhead was a bit brushy but nothing too bad so we rode it out. I was able to fit my full size through with just minor pinstripes. There was one minor tilted spot and a blowdown that was cut through at an odd angle and can be a bit tricky for bigger rigs. The trail beyond the Slide Lake trailhead had some clearing and I could probably get my full sized past the barrier obstical fairly easily but we were tired and didn't want to deal with it. smaller vehicles should have no problem.
