Renting a boat for two hours including snorkelling gear for two people should cost no more than 200,000 to 250,000 rupiah, or less than this if you're a shrewd negotiator.
The main spots are near the oil terminal towards Padang Bai and near the three small islands that can be seen off the coast of Candi Dasa where living coral still exists.
We did a snorkelling trip out to the islands straight offshore and while we saw plenty of fish, the coral had taken quite a beating and an hour was sufficient for where we stopped. Our boatman advised that there is a second spot on the far (more exposed) side of the islands that is better, but the waters were too rough that day for comfortable snorkelling on the exposed side of the islands.
