Is it worth going here?

Depends upon your interests and expectations. We've been there several times. Generally, this Indian community provides an exhibition of their culture plus a craft shop which is important to sales of local crafts. It is in a nice waterfront location.

I just saw your other question that refers to your limited time frame. In view of that I'd be inclined to leave Lennox Island for another visit to PEI.

Thanks!
Any opinion on North Cape vs. Eastern Shore?

We were at North Cape yesterday and had lunch in the restaurant overlooking the cape...and are heading for the Eastern end of the island tomorrow. We prefer the eastern end and will spend much of the summer there. It's less touristy, nice fishing harbours (chat with the fishermen to get an insight of the fishing season) and explore and nice beaches. For an overview check www.drivecrosscountry.net/RouteM1
