Beautiful Scenic route.. Along the highway 1, traffic a little slow on weekends but it opens up as you travel away from Mill Valley further north to Stewarts point. The ride from Stewarts to 101 through Skaggs is one of the best roads. The first 20 mins are rough, tight roads and surface is pretty rough but then it opens up and the road surface after the skaggs bridge is like an open track!
Pretty fun day trip, gone a few times and hardly seen any cops. Have to go early in the morning to beat the traffic.
