Try to find as much mud as possible. This weekend is going to be absolutely beautiful in terms of weather. Not much precip. in sight, cool daytime highs, *shudder*, I wish I was in Canaan Valley and not the Kanawha Valley right now. The high here, in Charleston tomorrow is 71-72 degrees, I'd like to imagine that it will be in the low 60s or upper 50s in the Valley tomorrow.
But do check-out the trails Davis has recommended... Plantation is a favorite, as is the Canyon Rim trail. If you're in the Blackwater Falls SP area (which you will be for Plantation), drive from the Lodge up past the ski area and down to the first trail on the right. Hike, or even bike out on this to the rocky point at the end of the trail. This is one of the pictures you'll see on a WV Tourism brochure, it's spectacular.
There's plenty of FREE good downhill to be had at Timberline Ski Resort as well... if you're feeling spunky drive over there, stop-in the shop, sign the release, grab a trail map and note those trails marked 'Hard', for they really are. I hope your brakes are in good shape. Stop-in at Blackwater Bikes as well for a run-down on everything bike-wise in the Valley as well.
