I was curious about the roads many on the island call "the loop". I'm no longer curious and I hope to hit it again to do all sorts of things to that road.
Temperatures fluctuated between 17 and 37 degrees due to elevation changes and exposure to the ocean. The ride into Port Renfew is amazing in itself.
A word of warning the road is extremely rough, and there's many 1-way sections. This is a service road for logging so expect trucks.
Enjoy the "ride".
