Both East ridge and West ridge trails are wide, graveled and pretty level for the first 0.5 mile, I imagine they are passable in a wheelchair, when starting from Skyline. Steam trail is pretty steep from Skyline and I don't recommend Wheelchairs on French, Starflower, Philip's Loop, Tres Sendas or Eucalyptus, etc trails
Stream trail is good when starting from the Redwood Road entrance (3rd parking lot)
