All hikers are required to have permits to ascend the subdome steps and the Half Dome cables seven days a week when the cables are up, the National Park Service said.
Park Rangers install the Half Dome cables each spring and take them down each fall, based on weather and trail conditions.
The cables are typically up from late May to early October.
All day use hiking permits are distributed by lottery via www.recreation.gov.
During the preseason lottery, 225 permits are available for each day that the cables are up.
