From "The Maui News" - July 31, 2008:
Beginning in July 2008 much of the Reserve will be closed for two years to allow resources to recover and officials to find ways to preserve and study the geology and other pristine areas.
During the closures, the road through the reserve, Makena-Keoneoio Road, will remain open, with access to La Perouse Bay, which also will be open to the public. However, people may not venture onto the lava rock alongside the road to La Perouse. Closed will be the unofficial trails to Kalua o Lapa (cinder cone area); Kalaeloa, known as the "Aquarium"; and Mokuha, also known as the "Fishbowl."
CLOSED for restoration. Scheduled to reopen in 2011.
Although the beaches are fairly small, it’s a popular snorkeling site. The scuba diving and snorkeling here are among the best in all of Maui. Although the beach is narrow, the waters are crystal clear, and there are lots of tide pools to explore.
La Perouse Bay is just beyond Ahihi-Kinau Reserve. In 1786 Jean-François La Perouse became the first Westerner to land on Maui, and this bay was where he disembarked.
