Thanks for the corrections Kelly, the island is it bit of gray zone for road reports so it's much appreciated. I've corrected the road geometry so let me know if there's anything else that needs fixing!
Looks good. Although only drivable to ~ 8.7 km. The rest is too narrow and bushy to drive.
Easy walking. Ebike or Moto would help. Could probably drive an ATV up it, but nothing bigger.
