Disneyland Plans a Creepy, Crawly Attraction : Amusement: The Indiana Jones Adventure to be opened next year will be filled with fake vermin and feature cliffhanger technology.

The Walt Disney Co. on Wednesday unveiled details of a new Disneyland ride that it promises will be its creepiest yet.

The Indiana Jones Adventure, being constructed between the main parking lot and Adventureland at a cost of more than $50 million, will feature a temple intentionally filled with fake bats, spiders, snakes and rats.

When it opens next year, Disney officials said, the attraction will feature technology designed to give visitors a different experience every time they ride.

“When you ride this ride, you will not be able to figure it out,” promised Tony Baxter, senior vice president of Walt Disney Imagineering, the company’s Glendale-based design arm.

The attraction was previewed Wednesday as part of a day of park festivities centered on the official opening of Roger Rabbit’s Car Toon Spin, scheduled to be the last major ride to open at the park before Indiana Jones Adventure.

In the meantime, Disneyland will have to manage without a major new attraction opening this summer.

It will need to hold its own against a new Batman-themed roller coaster at Six Flags Magic Mountain in Valencia, a Mystery Lodge special-effects show at Knott’s Berry Farm in Buena Park and a yet-to-be-named, deep-sea submarine simulation ride at Sea World in San Diego.

While not offering a new summer ride, Disneyland is expected to revamp its Main Street parade to promote the new animated “Lion King” movie due out in June.

After that, though, Disneyland will focus on the Indiana Jones Adventure, the park’s most ambitious effort since the Mickey’s Toontown children’s themed area opened last year.

The ride is based roughly on Steven Spielberg’s trilogy of matinee-style cliffhangers that starred Harrison Ford.

Visitors will find the ride behind the Jungle Cruise. After winding their way through a supposed archeological dig, they will board decrepit jeeps that take them through one of three doors. Each door offers a different experience, each with its own set of up-close-and-personal encounters with various types of vermin, engineers said.

“You will feel like they are in the vehicle with you,” said Imagineering Show Director Skip Lange.

After Indiana Jones, Disneyland will turn its attention to refurbishing the Tomorrowland portion of the park, which has not received a new attraction in the past few years, said Judson Green, president of Disney’s theme park division.
