Tidal Pools

[Jimbo]

When I was in high school, I took a course in Marine Biology at the 4 C's. For our study of tidal pools we went to Chapin Beach in Dennis, on the outgoing tide. If you hit it right, in addition to the pools there are awesome flats out to the Bay which have wadeable draining channels where you can find more aquatic sealife, Sometimes what washed in and was left on the flats can be as exciting as what's in the water. And the thing about Chapin is that generally it's not crowded at all.
The National History Museum in Brewster is just a bit further up 6A. You might also contact the Cape Cod National Seashore and see if any of their rangers do programs like you're looking for. Both have websites you can check out.
