Half Dome in Yosemite National Park is one of the most iconic hikes in the United States. Rising 8,800 feet above sea level, this granite monolith draws hikers, adventurers, and nature lovers from across the globe. However, hiking Half Dome isn’t just about stamina and preparation—it requires a permit. In this guide, we’ll walk you through everything you need to know to secure a Half Dome permit, prepare for the hike, and make the most of your Yosemite adventure.
Why You Need a Permit to Hike Half Dome
Yosemite National Park introduced the Half Dome permit system to protect the delicate ecosystem, manage overcrowding, and ensure hiker safety. Without a permit, hikers are not allowed to climb the cables to the summit. Here’s what you need to know about permits:
-
Permit Types: There are two main ways to get a Half Dome permit: the preseason lottery and the daily lottery.
-
Safety: The permit system helps rangers manage the number of hikers on the cables, which can get extremely crowded.
-
Conservation: Limiting the number of hikers protects the natural environment from erosion and human impact.

1. Preseason Lottery
The preseason lottery is the most popular way to secure a permit for a specific date in the upcoming season.
