Tons of trails in that area. Just south of Carson City outside of Gardnerville. There is Johnson lane and the pine nutz area. There might be a month or two when that area is a bit snowed out. Spring and fall are best in the summer head up into the mountains. From what I hear sand mountain is lame for bikes. Tons of quads and buggies. But there is winnamucca dunes and two different spots down by tohnapha.
