LOS ANGELES -- The Matterhorn at Disneyland reopened Tuesday after a woman who rode the bobsled ride was hospitalized.

The woman said Monday night that she felt sick after the ride. The 62-year-old woman remained hospitalized Tuesday night in critical condition.

"She did go over to guest First Aid and asked if she could lie down," said Maria Sabol of the Anaheim Fire Department. "She did for a while. When nurses determined that her condition was not improving, they did call our medic (who) is at the park."

The woman's doctor said she had high blood pressure and had not taken her medication.

State inspectors were investigating Tuesday morning. Authorities said they were unable to find anything wrong with the ride.

The ride's bobsleds travel about 18 mph through turns on a mountain-like structure.
