Walk on the ocean floor thanks to the Bay of Fundy's high tides (second highest in the world.) Truly a fabulous sight. Bring your camera. Check the website for the low-tide time, and get there within three hours on either side of low tide to see the islands best. (Kayaking is available if the tide's high.) A nice 10-minute walk through the woods takes you to a large stairwell to the ocean floor, where you can easily walk among a half-dozen enormous (more than 30 m high) columns of fir tree-topped sandstone islands. A golf-cart shuttle can whisk you back to the park information facility, which features a good explanation of how the islands came to be, a snack bar and gift shop. The ride from Moncton is about 45 minutes. Entrance to Fundy National Park is another 30 minutes but definitely worthwhile in good weather.
The Hopewell Rocks, also called the Flowerpot Rocks or simply the Rocks, are rock formations known as sea stacks caused by tidal erosion in the Hopewell Rocks Ocean Tidal Exploration Site at the Hopewell Rocks Provincial Park in New Brunswick, Canada. They stand 12–21 metres (40–70 ft) tall.

Crossing the Petitcodiac River into Riverview, you can hike the Dobson Trail, a continuous footpath stretching 58 km from Riverview, NB to the northern boundary of Fundy National Park near Alma, NB. There is some accessibility in the initial section of the trail (wheelchair accessible and guide wire). If you are not willing to follow all the path (about 3 days hike), do the loop trail along Mill Creek (1 km, about 1 hour). Particularly beautiful in the fall.
Watch the "wall of water" in the river, where an amphitheater-style seating provides bore viewing. The tidal bore happens when the Bay of Fundy rising tide brings water counter to the normal flow of Petitcodiac river. The once-famous thundering flow has been reduced to a 6-inch (150 mm) ripple by nearby causeway, but still an unusual sight when it is visible. An electronic display board at the park, or the folks at the city's information booth on Main St, can tell you when to see this phenomenon, which occurs twice a day. Occasionally you will see surfers chasing the bore!
