The lure of forbidden hiking trails continues to cause problems for fire rescue crews. Yesterday a hiker was airlifted from Lulumahu Falls in Nuuanu. Today, a hiker got stuck at the top of the Stairway to Heaven trail. Fire officials responded to the call around 2 A-M. They say the lone hiker entered from the Moanalua side of the trail and got stuck at the summit when the weather turned bad. The search was suspended until first light this morning. The hiker was not injured.
