We are headed to Monaco for a conference in early September. We have about 3 free days to travel and explore the area. I am looking for suggestions for day trips we can take from Monaco to nearby locations. We are up for heading toward Nice, maybe heading toward Italy and wouldn't mind some hiking/outdoor ideas too. My husband has never been to Europe so I want to give him a variety of experiences in a short amount of time. Any suggestions would be great! The guide books are overwhelming me!
