We hiked 8k within this coastal preserve, just before you reach Five Islands, Nova Scotia. You have two loop to choose from: Headlands & Economy.
Both are about equal distance and both offer great views of the Bay of Fundy. Note that the trails are maintained by two distinct groups and you might find that the trail conditions is not consistent.
What you do get is a nice footpath along the cliffs, I would leave the pets at home for this one. There are a few spots where you can get to the ocean floor. Since this is the Bay of Fundy, time your visit at low tide and you won’t be sorry.
