The lower 2/3 mile of Speed King is open. There are three easy ways to get onto the trail.
1) Permanent access trail off of South Ridge Tr: The access is just past the first road crossing for South Ridge Tr. It is signed. This access goes to the mid-point of the trail.
2) Temporary access trail off of South Ridge Tr: This access is a little ways after the second switchback overlooking the lake on South Ridge Tr (the one with a good view). This trail is signed. The trail is about 1/4 mile long and fairly flat. There are flags along the way to keep you on the right path. This goes to the top of the currently open trail.
3) Access from Lower Hooligan. This road access is from the first road crossing on Lower Hooligan (just below the windy-curvy jumpy section). Take a left on this road. The trail is about 1/4 mile up the road. It is a bit of a climb, but not too much really.
