Fodor's Expert Review Ocean Explorer Centre
On the Firth of Lorn, this imaginative venture lets you get a look under the sea. Hands-on exhibits include microscopes where you can observe tiny algae and a live undersea camera where you can see what's happening below the waves. Part of a scientific research center, it's educational but also accessible and fun. There is a bright little café and a shop with books on marine science and other topics. It's 2 miles from Oban—follow the signs for nearby Dunstaffnage Castle.
