There is a boat from CR directly to Fort Wilderness, where Trails' End is located. Make sure you get off at Fort Wilderness, not Wilderness Lodge; the boat from CR docks at both.
First boat leaves about 6:45am daily.
Scooters or Guests in wheelchairs cannot be accommodated on these boats. They can walk or ride the Resort Monorail (starting at 7am) to MK. Boats from MK to Fort Wilderness do accommodate scooters or wheelchairs, starting around MK opening time. Earlier than that, a bus from MK to Wilderness Lodge would be required (starting about 6:30am), and then a 2nd bus from WL to Fort Wilderness Settlement.
