This used to be the best place for snorkeling and shallow diving, but it was damaged during El Niño a couple of years ago (the regeneration process is bringing this site back rapidly). That said it is a top spot for night dives, the rubble between the hardcoral-bommies is a perfect place to spot several rare crabs, flatworms, bigger nudibranchs like the Spanish Dancer and many others.
A shallow dive with 10m/35ft as maximum depth gives you plenty of time to play in the "garden"
