Leave early to avoid peak traffic; travel east on Autoroute 20/132 toward Rimouski and Le Bic — scenic provincial highway with several gas and grocery stops en route.
Stop for a quick picnic (groceries at an IGA/Metro) or a casual café in Trois‑Rivières — convenient and dog‑friendly outdoor options; saves time and keeps your dog comfortable.
Explore the bay, ridges and tidal flats on short, dog‑friendly trails (park open dawn to dusk; visitor centre typically 9:00am–5:00pm in shoulder season). The coastal views are a gentle introduction to the trip.
If you want local seafood, drive 15–25 minutes into Rimouski for fresh catches at a bistro (verify hours); otherwise a relaxed camp‑cooked meal is practical and dog‑friendly.
Grab coffee and pastries in Rimouski (many bakeries open ~7:00am) or make breakfast at the camper; save time and let your dog stretch before the next drive.
Walk viewpoints near the town to view Percé Rock and Bonaventure Island (the shore viewpoints are dog‑friendly; boat/island visits have separate rules).
Enjoy fresh seafood in Percé at a waterfront restaurant (many restaurants remain open through September but double‑check hours and outdoor seating for your dog).
Take the guided boat to Bonaventure Island to see the big gannet colony and seabirds (boats typically run daily in summer/early fall, roughly 9:00am–5:00pm but schedules change in shoulder season). Dogs are usually not allowed on guided island boats — plan dog care in the camper or onshore.
Choose an easy coastal trail or the Mont‑Ste‑Anne viewpoint for expansive views; check trail access times and leash rules (most short trails are dog‑friendly on leash).
Explore capes, coastal trails (e.g., Les Graves, Cap‑Bon‑Ami) and dramatic cliffs; Plaisirs at the Interpretive Centre are typically open 9:00am–5:00pm. Many trails permit dogs on leash; verify specific trail rules.
Fuel up with a hearty breakfast in Campbellton before a long scenic drive down New Brunswick’s north shore toward Shediac and the Confederation Bridge area.
This is a longer day of driving with coastal detours; stop at viewpoints, small Acadian villages and parks en route (stretch breaks for your dog every 2–3 hours).
Shediac is famous for lobster: enjoy a lobster roll or seafood plate at a seaside shack (many have outdoor areas — check dog policy and open hours as some close after summer).
Walk at Cape Jourimain (NB side) and visit beach viewpoints near the bridge; birding and coastal views are pleasant — parks open daytime, visitor info may be seasonal.
Plan to cross the bridge late afternoon for easier arrival in PEI; the bridge is open 24/7 — toll is charged when entering PEI (verify current toll rate at time of travel).
Stroll the historic downtown and Confederation Landing — flat, dog‑friendly sidewalks make this a relaxed morning activity (museums have varied hours; check ahead).
Head to Cavendish for red cliffs, dunes and scenic coastal trails; the national park has dog‑friendly beaches outside posted protected zones, but check rules for specific areas.
Visit sandy beaches and dune boardwalks; some beach sections have leash rules — check posted signage. Great for a long beach walk with your dog in shoulder season.
Enjoy a picnic on the beach or dine at a nearby lobster/seafood takeout; many stands remain open in early September, but hours shorten after Labour Day.
North Cape offers dramatic bluffs, a boardwalk and a wind energy learning centre (seasonal hours; check ahead). The area is good for late‑afternoon light and coastal walks.
Rent bikes (many rental shops allow trailer/ dog‑friendly options) to ride the Confederation Trail or visit a local vineyard for sampling (check pet policies).
Head off early to maximize daylight for the long drive back to Montreal; remember the eastbound bridge toll is charged when entering PEI/Westbound — verify current policy and payment method.
Expect 7–9 hours of driving depending on stops; plan 2–3 breaks for your dog and meals. Consider breaking the drive with a scenic lunch stop in New Brunswick or Quebec.
