The incident drew a significant response from the Los Angeles Fire Department on Saturday, June 6, 2026, near 1900 Wattles Drive in Hollywood Hills West, an area closely associated with Runyon Canyon and some of Los Angeles’ most heavily used urban hiking routes.
According to LAFD incident alerts, firefighters were dispatched at about 6:42 p.m. for a reported hiker in grave medical condition. The department said approximately 26 LAFD personnel were assigned to the incident.
In a later update, LAFD said Air Operations lowered rescuers to the patient and that medical treatment was administered. The hiker was ultimately determined deceased at the scene. Park rangers and the Los Angeles Police Department were requested to help secure the area.

A reminder for LA hikers
Runyon Canyon and the surrounding Hollywood Hills trails are familiar to many Los Angeles hikers, but urban trails can still become emergency scenes quickly. Crowds, exposed sections, uneven terrain, limited shade, and delayed access for rescue crews can all complicate a response.
For hikers heading into Runyon Canyon, Griffith Park, the Santa Monica Mountains, or other LA-area trails, basic precautions remain worth taking seriously:
- Carry more water than you expect to need, especially late in the day.
- Tell someone where you are going and when you expect to return.
- Check weather, trail closures, and fire conditions before leaving.
- Keep enough phone battery for navigation and emergency calls.
- Turn back early if you feel dizzy, overheated, short of breath, or unusually fatigued.
- Call 911 immediately if a hiker appears to be in serious medical distress.
This story is also a reminder that even short, popular hikes inside the city deserve the same respect as more remote mountain routes. Familiarity does not remove risk.
