Merrimack River shore access

Not trying to spot burn, but I was reading some older reports from last year and read the pike fishing is good in the fall here.

Wondering if there was enough shore access spots along the river to justify making the drive up one day and trying my luck this fall.

I don't mind hopping spots with the car or bush wracking a little. But if it's all residential or if all the shore is inaccessible by land I won't bother.

Thanks.
