Get a raft use either a chest or Korok leaf to push the raft. One raft is at Lurelin Village another one near Chaas Qeta Shrine. Usually, I just get a few stamina recovery items like Enduring Fried Wild Greens or stamina elixir. Go to Muwo Jeem Shrine. You jump and paraglide to the Eventide Island. Use an stamina recovery or two item unless you have two yellow stamina wheels and max stamina.
