HONOLULU (AP) -- Hawaii officials have long been warning people to stay away from Sacred Falls, a dramatic waterfall where a landslide killed eight hikers more than 15 years ago.
But hikers keep returning, encouraged by gushing reviews on websites and YouTube.
Now the state is pushing back with its own online campaign.
It's releasing a video showing a law enforcement officer citing people for criminal trespassing. It features interviews with officers talking about risking their own lives to rescue people who get in trouble in the valley.
Sacred Falls is about an hour's drive from Honolulu on Oahu's lush eastern side. A park there used to be open to the public, but the state Department of Land and Natural Resources closed it in 1999.
That's the year tons of boulders, some the size of small cars, came crashing down on dozens of hikers visiting on Mother's Day.
Witnesses at first mistook the roar they heard for a flash flood. Instead, a chunk of the upper cliffs had slid down to the base of the falls where people were sitting and swimming.
More than 50 people were injured in addition to the eight killed.
The department has since posted signs warning about flash floods and rock falls at the park entrance and along the old trail. Signs note it's illegal to enter and that the fine for trespassing is $2,500. Even so, law enforcement officers issued more than 120 citations for trespassing last year.
Officers say people tell them they read about the hike online and that the warning signs are only posted to protect the state from liability.
