This page covers two main areas along the coastline of the Bay of Fundy north of Saint John. Further down the page is The Rocks Provincial Park. First though is Fundy National Park. Most of Fundy National Park is actually inland with several multi-day hiking trails that never come near the shoreline. We however focused along the coast. This covered bridge is in the southeast of the park in the Ship Haven area.
This is the namesake ship haven - a protected bay that ships could harbor in and load supplies as well as logs from the nearby mill. Of course this is Fundy so at low tide (like here) there isn't much water in the bay. At high tide this would be navigable.
Further up the coast and still at low tide, this is Herring Beach. Way off in the distance there are the stairs that come down from the parking area. The high tide isn't quite up to them but it is pretty close. At low tide, Herring Beach is a vast plain of gravel and sand.
Looking the other direction, the water in Herring Cove has receded quite a ways. Those people on the top right are down near the water line. The small town in the distance is Alma which works as the supply town for the park. Incidentally, vast plains of sand and gravel are apparently a lot of fun if you're 1 year old.
Looking out across the Bay from Herring Cove, this is the Apple River area of Nova Scotia out near Cape Chignecto. This is a remarkably long drive (Google maps says over 3 hours) from here despite how close it seems, particularly at low tide.
This is probably the classic 'postcard view' of New Brunswick featured on the cover of all the respectable New Brunswick free travel guides available at a highway rest area near you. This is The Rocks Provincial Park. For whatever reason it is commonly called Hopewell Rocks (after the nearby 'town'). Some dramatic weathering and tidal action has created a lot of interesting rock formations here. This is another place you really want to visit at low tide so you can wander around on the sea floor. At higher tides you do have the option of kayaking.
These odd formations which are eroded at the bottom and have mini-forests growing on top are called Flowerpots. The visitor center at The Rocks is around 1km (0.6 mile) from the main viewing area. There is a tram that makes the trip or you can just walk along the nice shaded path.
At low tide you can pretty much wander wherever you like. As the tide starts to return they begin closing off access to parts of the beach and eventually herd everyone back up to the cliff. Incidentally the sea floor (as you may expect) can be pretty mucky. Best to wear good hiking shoes.
The Rocks is easily the single most crowded location we visited on our entire trip in the Maritimes. It's probably the only place we saw tour buses. Most of the crowd seems to mill around directly beneath the stairs to the sea floor however. Once you go a couple coves away it seems mostly deserted.
This is actually one of our favorite views from the trip. Close to the visitor center is this lookout of Daniel Flats. This is a vast mudflat at low tide with seawater channels snaking through it. You can actually hike to a beach down on the right (from this vantage) although obviously swimming is not allowed.
