Three days is short for a peninsula this long, but it is enough to see the part that most people come for, if you accept that you will drive a lot and choose what to leave out. The plan below puts the headline sights in the middle, with a night in Percé and a night in Gaspé town, and it assumes you arrive by car from Québec City or Rimouski on the north coast. If you are arriving from New Brunswick along the Baie des Chaleurs, run the same plan in reverse.
Before you start
Most of what you want to see is open from late May or June to mid October, so a three-day trip belongs to that window, and the boat to Bonaventure Island needs good weather. Book your two nights first, because there are few rooms. Fill the car before long stretches, carry water and a windproof layer, and check each site's hours the week before you travel, because seasons are set each year.
Day one: the north coast to Gaspé
If you enter along the St. Lawrence, stop at the Jardins de Métis in the morning, which is the western gateway to the peninsula and a two-to-four-hour visit. Stop at the Matane salmon observation centre if it is open, because it takes thirty minutes and costs nothing. Then follow route 132 around the coast toward Gaspé, with a break at Exploramer in Sainte-Anne-des-Monts if you have children. It is a long driving day of several hours, so do not try to add more. Sleep in Gaspé town at Hôtel Baker, which has a pool and a restaurant, or at the budget Rodeway Inn.
Day two: Forillon and Gaspé town
Spend the morning at Forillon National Park, entering from the South Area near town. Walk the coastal trails, look for seals from the shore and, if the season allows, take the whale cruise from Grande-Grave. Drive through the park to Cap-Bon-Ami for the sea cliffs and to the Cap-des-Rosiers lighthouse for the tallest lighthouse in Canada. Come back to town in the afternoon for the Musée de la Gaspésie or the Birthplace of Canada village, or the Gespeg Mi'gmaq site if you want the oldest story. Have dinner in town.
Day three: Percé
Drive south from Gaspé to Percé, a long morning that passes through fishing villages. Go to the wharf for the straight-on view of Percé Rock, which is free, and take the boat to Bonaventure Island if you want the gannet colony, allowing three to four hours on the island. If you prefer to stay on land, the Percé UNESCO Global Geopark gives the high view from its glass platform, 200 metres above the sea. Sleep in Percé at Riotel Percé, which looks at the rock, or in Gaspé town if you plan to drive back.
If you have a different shape of trip
If you want the mountains instead of Percé, swap day three for Gaspésie National Park, driving up route 299 from Sainte-Anne-des-Monts and walking a trail that suits your legs. If you want the south coast, swap in Miguasha and Paspébiac. You cannot do all of it, and the honest advice is to choose one headline sight per day and enjoy the drives between them.
What to leave out
In three days, leave out Gaspésie National Park's big hikes, the south coast and anything that needs a long detour. Skip long museum visits unless the weather turns. The Percé boat and Forillon are the sights that justify the distance, and everything else is a bonus.
Driving times to plan around
The distances are the real constraint. Gaspé town to Percé is roughly an hour and a half to two hours each way, Gaspé town to the Cap-des-Rosiers end of Forillon is under an hour, and the run from the Jardins de Métis to Gaspé takes most of a day once you add stops. Build in a break every ninety minutes, keep fuel above half and avoid arriving after dark on the coast road, where wildlife and fog are real hazards. Treat the times as estimates and add a margin in summer traffic.
Booking order
Reserve the two beds first, then the Bonaventure Island park fee online, then dinner if you are visiting in July or August. Buy the boat ticket in Percé on the day, once you have seen the weather. Keep one half day free for the unexpected, whether that is a fog delay or a viewpoint you want to revisit.
Weather and fallback
Fog and wind can cancel boats, so keep the geopark or the museum as a fallback for Percé, and allow a spare hour in each day. A rainy day suits the Musée de la Gaspésie, Exploramer and Paspébiac. Pack for four seasons even in July.
