HONOLULU — 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.
