Black Rock at Kaanapali is your best bet - very safe, lots of people and some fairly decent coral blooms that are deep enough to prevent damage from fins and feet. Lots of fish and the odd ray - if the current and surf are calm, follow the rock out to the edge for the best snorkeling.
You'll probably see more at Black Rock than Molokini which is best for scuba and snuba.
