Minas Basin: Where the World's Highest Tides Live
Walking the ocean floor at Burntcoat Head, five islands from a cliff-top, dinosaur fossils in Parrsboro, and the Truro tidal bore - the complete guide to Nova Scotia's tidal heart.
The Minas Basin is the tidal powerhouse of the Bay of Fundy - the shallow eastern arm where the world's highest tides, measured at Burntcoat Head, rise and fall up to 16.3 metres (53.5 feet) twice a day. Every six hours and 13 minutes, roughly 160 billion tonnes of water pours in and out of the bay, and in the Minas Basin you can watch it happen up close: walk the exposed ocean floor at low tide, then return hours later to see the same spot underwater. Around the basin's red sandstone shores sit Five Islands Provincial Park, the fossil-and-gem town of Parrsboro, the tidal bore at Truro, and some of the best coastal geology in Canada. This guide covers the basin's highlights, how to time the tides, and how to build a day trip or weekend loop around them. For tide times and the full coastal picture, see the complete Bay of Fundy guide.

Tide Science in Plain Language
Why the Minas Basin? The short answer is a funnel and a resonance.
The funnel effect
The Bay of Fundy narrows from roughly 80 km at its mouth to about 5 km at the Minas Basin's head. The same volume of water is squeezed into a smaller space, so it rises higher.
The resonance
Water sloshing in the bay takes about 12.5 hours to complete a cycle - almost exactly matching the ocean tide's 12-hour rhythm. Each incoming wave adds energy to the next, amplifying the rise.
The numbers
Average spring tide at Burntcoat Head: 14.5 m (47.5 ft). Extreme recorded range: 16.3 m (53.5 ft) - the Guinness World Record for the highest tides on Earth.
Spring vs neap tides
Spring tides (highest) follow full and new moons; neap tides (lowest) follow quarter moons. For the most dramatic change, visit within two days of a full or new moon.
What the tide leaves behind
At low tide the basin floor is a living laboratory - tidal pools, mud flats, periwinkles, hermit crabs, and the protected Atlantic Mud Piddock, a clam found only in the Minas Basin.
Two tides a day, 50 minutes later
High and low tide shift about 50 minutes later each day. Check tide tables before you go - the window to explore the ocean floor is roughly 2 hours either side of low tide.
Burntcoat Head: Walk the Ocean Floor
The single best tidal experience in the province, at the exact spot where the Guinness World Record was measured.
Burntcoat Head Park sits on the Minas Basin shore near the village of Burntcoat, about 1 hour 15 minutes from Halifax. From the parking lot it's a 3-4 minute walk to the replica lighthouse, then stairs with railings down to the exposed seabed at low tide. You can wander out across rippled sand and mud past red sandstone cliffs, sea caves, and tidal pools, with the water line visibly retreating and returning. The park's interpretive displays explain the geology, and guided ocean floor tours run in summer for the full naturalist treatment.
Gear up
Sturdy, washable, waterproof footwear is essential - the seabed is muddy, uneven, and slippery. No flip-flops or crocs. A foot wash is available mid-May to mid-October.
Respect the critters
Tiptoe through the periwinkles - the exposed creatures are vulnerable. Don't walk in the Piddock Protection Area (left of the stairs), and never collect fossils without a Heritage Research Permit.
Real fossil finds
Important fossils have been discovered here, including Teraterpeton, a beaked archosaur that lived alongside early dinosaurs. Find one? Photograph it and tell the Fundy Geological Museum.
Climb the lighthouse
The historically-accurate replica lighthouse has stairs to the top - the best elevated view over the basin. Gift shop, washrooms, picnic tables, gazebo, and free Wi-Fi are on site.
Season & hours
Mid-May to mid-October, 9 AM - 5 PM daily for the gift shop and washrooms. Park grounds are accessible after hours at your own risk - the ocean floor should only be explored in daylight.
Safety first
Check the tide schedule before visiting, never explore the floor near high tide, and keep an eye on the water's return. No overnight camping is permitted.
Five Islands Provincial Park
Five islands, 90-metre cliffs, and the best cliff-top tide viewing on the basin.
Five Islands Provincial Park takes its name from the five offshore islands - Moose, Diamond, Long, Egg, and Pinnacle - that rise from the Minas Basin. The 1,000-hectare park on Route 2 near the village of Five Islands combines a saltwater beach, 92 campsites, and hiking trails, most famously the Coastal Trail to a 90-metre cliff-top lookoff with jaw-dropping views across the basin to Cape Split. From the lookoff you can literally watch the tide race in and out below you - a perspective you can't get from the ocean floor.
| Trail | Distance | What you see |
|---|---|---|
| Coastal Trail | Short (lookoff) | The signature view - 90 m cliffs, five islands, Cape Split across the basin |
| Red Head Trail | 2.2 km loop | Acadian forest to a headland with panoramic bay views |
| Economy Mountain Trail | 3.8 km one way | Strenuous climb to a 360° view over Five Islands, Cobequid Bay and beyond |
Camping runs June 5 to October 12, 2026 with unserviced, serviced, walk-in, and group sites - book at novascotia.goingtocamp.com, and reserve ahead for July-August weekends. The beach is best at mid-to-low tide when the sand flats expose; swimming is unsupervised and the tide is extreme, so stay alert. Park phone: (902) 254-2980.
Parrsboro: Fossils, Gems & the Museum
The basin's cultural anchor - a historic shipbuilding town that is also one of the most important fossil sites in Canada.
Parrsboro, on the north shore of the basin, has been collecting the world's attention since the 1980s, when amateur fossil hunters began finding dinosaur and reptile remains in the low-tide cliffs. The Fundy Geological Museum (162 Two Islands Road) tells the 300-million-year story with genuine fossils - including one of the world's smallest dinosaurs - minerals, an interactive tide-pool touch tank, and it doubles as the town's Visitor Information Centre with tide times and maps. Summer hours (May 12 - Sep 27, 2026): Tuesday-Sunday 9:30 AM - 4:30 PM; adult admission $8.50, kids 6 and under free.
Fossil hunting
Guided beach tours from the museum visit fossil beds exposed only at low tide. Collecting without a permit is illegal - but the tours show you what to look for, and the museum identifies finds.
Gem & Mineral Show
Every August since 1966, Parrsboro hosts Atlantic Canada's premier gem, mineral, fossil and jewelry show - 30+ exhibitors, gold panning demos, and workshops. 2026 dates: August 21-23.
Ottawa House Museum
A multi-building historic site on the Parrsboro waterfront - one of the province's oldest museums - with shipbuilding, Mi'kmaq, and Victorian collections. Open summer season.
Shipbuilding heritage
Parrsboro once launched more ships than any port in Canada. The harbourfront and walking trails tell the story, and the town's cafés and galleries make a pleasant lunch stop.
Harbour views
Parrsboro's waterfront looks straight across the basin - a favourite spot for sunset photos and for watching the tidal bore ripple up the Parrsboro River.
Geopark hub
Parrsboro sits at the heart of the Cliffs of Fundy UNESCO Global Geopark - the museum is the best introduction to the whole 165-km coastline.
The Truro Tidal Bore
A rolling wave of incoming tide that reverses a river in minutes - and the basin's most accessible free show.
Twice a day, the rising Minas Basin tide pushes a visible wave front - the tidal bore - up the Salmon River at Truro, reversing the river's flow. The best free viewing spot is Tidal Bore Park on the Truro waterfront, where benches face the river and a signboard posts the daily bore time. Arrive 15 minutes early: the bore itself lasts only a few minutes, and the fun is watching the river stop, reverse, and rise before your eyes. For the adrenaline version, tidal bore rafting on the Shubenacadie River runs zodiac rides through the standing waves - the only place in North America you can do it.
Driving Routes & Itineraries
The Minas Basin is compact enough for a full day trip from Halifax and rich enough for a weekend loop.
Day trip from Halifax
Morning: drive to Burntcoat Head (1.5 h) for low-tide ocean floor walk. Lunch at the park or in Truro. Afternoon: catch the tidal bore at Truro's Tidal Bore Park, then the 2.2 km Red Head Trail at Five Islands en route home. ~300 km round trip.
Weekend loop
Day 1: Halifax → Truro bore → Five Islands (camp or stay in Truro). Day 2: drive the scenic Route 2 shore to Parrsboro - Fundy Geological Museum, Ottawa House, beachcombing - then Burntcoat Head for the afternoon low tide before returning.
Combine with the Annapolis Valley
Cross the basin from Parrsboro to Wolfville via the ferry-free drive through the Cobequid Pass, or continue to the Annapolis Valley wineries for a geology-and-grapes weekend.
Best tide-viewing windows
Target a spring tide (full/new moon ± 2 days) with low water between 10 AM and 4 PM. Full and new moon dates are listed in every tide table - plan the trip around them for the most dramatic basin.
Where to stay
Camp at Five Islands, stay in Truro for the bore, or base in Parrsboro. See Where to Stay in Nova Scotia for region-by-region lodging options.

Minas Basin - FAQ
- Where is the Minas Basin?
- The Minas Basin is the easternmost arm of the Bay of Fundy in Nova Scotia, wrapping around the north shore of the province between the Annapolis Valley's North Mountain and the Cobequid Hills. Key towns and parks on its shores include Truro, Parrsboro, Five Islands, Burntcoat Head, and Wolfville.
- Why does the Minas Basin have the highest tides in the world?
- The Bay of Fundy's funnel shape and the 12.5-hour tidal rhythm create a natural resonance that amplifies the tide. At the Minas Basin - the bay's shallow, narrowing eastern end - the average spring tide reaches 14.5 metres (47.5 feet), and the extreme range recorded at Burntcoat Head is 16.3 metres (53.5 feet), the highest in the world, confirmed by Guinness World Records.
- Can you walk on the ocean floor at Burntcoat Head?
- Yes - at low tide the ocean floor is exposed at Burntcoat Head Park, and you can walk out onto the seabed past red sandstone cliffs, sea caves, and tidal pools. Always check the tide schedule first, wear sturdy washable footwear, and stay out of the Piddock Protection Area. Guided ocean floor tours run in summer.
- What is the Truro tidal bore?
- The tidal bore is a rolling wave of incoming tide that surges up the Salmon River at Truro twice a day. The best place to see it is at the Tidal Bore Park on the Truro waterfront - check local tide tables for the bore time, arrive 15 minutes early, and watch the river reverse direction.
- How far is the Minas Basin from Halifax?
- Truro is about 100 km (1 hour) from Halifax via Highway 102. Burntcoat Head is roughly 1 hour 15 minutes, Five Islands about 1 hour 45 minutes, and Parrsboro about 2 to 2.5 hours. It's an easy day trip or a weekend loop combining the basin towns.
- When is the best time to see the highest tides?
- Spring tides (the highest of the month) occur just after full and new moons, roughly twice a month. For the most dramatic change, visit within a day or two of a spring tide and stay for both low and high water - the basin fills and empties about 14 metres vertically in just over six hours.
