Saint John is a good base for day trips, because the best of the Fundy coast lies within two hours of the city by road. This guide groups the options by direction and notes how long each takes, what depends on the tide and which can be combined.
East to St. Martins and the Fundy Trail
The nearest coastal day out is the village of Fundy-St. Martins, about an hour east of Saint John. Its sea caves, carved by the Bay of Fundy tides, can be visited around low tide on foot or on a guided hiking or kayaking tour. The village also has Quaco Head Lighthouse, the Quaco Museum, Black Beach and the Split Rock Trail. Beyond it the Fundy Trail Parkway, a 30 kilometre coastal road and trail park, runs from mid-May to late October with lookouts, beaches and forest. Plan the caves for low tide, lunch in the village and the parkway in the afternoon. The parkway charges a vehicle fee, and services along it are limited.
Northeast to Hopewell Rocks and Cape Enrage
Hopewell Rocks is a little under two hours from Saint John and is the big tide experience: you walk the ocean floor between sea stacks around low tide. It is open from mid-May to late October and the ticket is valid for two days. Cape Enrage, a short drive away, has an 1838 lighthouse on 46-metre cliffs, a zipline, rappelling, a restaurant in the keeper's house and a shop of local crafts. The two make a natural day together, and Fundy National Park and Alma are a little further on if you want to stay the night. Check the tide table first, because the day's timing is set by low water.
Northeast again to Fundy National Park
If you are driving to Hopewell Rocks, Fundy National Park is the usual extension. It has waterfalls, beaches and ocean-floor walks at low tide, and the village of Alma at its gate. This is a long day from Saint John, so many visitors stay a night.
West to St. Andrews by-the-Sea
St. Andrews is roughly an hour and a half from Saint John. It is a seaside town with whale watching in summer, Kingsbrae Garden, the Blockhouse and Ministers Island, which you reach by driving across the ocean floor at low tide. A day trip is possible, but the cruise, the garden and the island all depend on season and tide, so an overnight at the Algonquin Resort or the Treadwell Inn works better.
Southwest to Grand Manan
Grand Manan is the most adventurous day out. Drive to Blacks Harbour, about an hour from Saint John, and take the Coastal Transport ferry, which runs daily and has lounges, viewing decks and a cafeteria. The island has sea cliffs, coastal trails, lighthouses and fishing wharves, and whales and seabirds in summer. A same-day return is possible with an early sailing and a reserved return, but fog can delay the ferry, so an overnight stay at the Marathon Inn is more relaxed.
Far west to Campobello Island
Roosevelt Campobello International Park is a long way from Saint John and is better visited from St. Andrews. It has a 34-room cottage museum, 11 hiking trails and free admission, and you need a passport because the bridge route passes through Maine.
Tours
If you prefer not to drive, guided shore tours and coach tours run from Saint John to the sea caves, Hopewell Rocks and Fundy National Park, usually with set pick-ups, so check the stops and duration when you book. Hopewell Rocks admission can also be bought in advance.
Planning tips
Check the tide table for every trip, fill the tank before the coast roads, carry water and a windproof layer and tell someone your plans because mobile service can be patchy. Most coastal day trips are for the warm months, from mid-May to mid-October, so in winter stick to the city, Rockwood Park and the Reversing Falls.Most coastal day trips are for the warm months, from mid-May to mid-October, so in winter stick to the city, Rockwood Park and the Reversing Falls.
Choosing between them
If you only have one day, pick by interest. For the tide and the ocean floor, choose Hopewell Rocks with Cape Enrage. For the shortest drive and a mix of caves, beaches and cliffs, choose St. Martins and the Fundy Trail Parkway. For a seaside town and gardens, choose St. Andrews. For a real adventure with a ferry and whales, choose Grand Manan and stay the night. Whichever you choose, set out early, because the tide waits for no one.
