The page on Mauna Loa's Observatory Trail says that most car rental companies prohibit driving on Saddle Road. I know this is now out of date and it has been paved.... but does anyone know the state of the road to the Mauna Loa Observatory? Can I drive a rental car up it? Trying to get a straight answer out of the rental car companies is hard!
If I can't can anyone suggest an alternative way to the top? The other trails are really long - perhaps a tour?
