Areas of Yosemite National Park that were burned in a massive wildfire last year are being opened to the public again, but with a word of caution.

Park spokesman Scott Gediman said Wednesday that visitors to scorched parts of Yosemite need to watch out for dangerous trees, uneven ground, possible rock falls and debris on the trails. 

The burned areas of the park have been closed since the Rim Fire started August 17th.

The fire is the third-largest wildfire in California history and the largest recorded in the Sierra Nevada.
