The best time to go to Rivière Éternité is during the summer months, from June to September, when the weather is pleasant and all outdoor activities are available.
During this period, the average daily temperatures range from 18°C to 25°C, making it ideal for exploring the region's natural beauty. The longer daylight hours also mean more time for hiking, kayaking, and boat tours on the Saguenay Fjord. This is especially good for couples who want to enjoy scenic walks and boat trips together, with plenty of opportunities for photography.
Families will also find summer to be the most convenient time to visit. The warmer weather allows for comfortable exploration of the trails in Parc national du Fjord-du-Saguenay, and children can enjoy activities like paddleboarding or wildlife watching without the chill of other seasons. Many of the local attractions, such as the Via Ferrata or the ferry to Tadoussac for whale watching, operate fully during these months.
While autumn offers beautiful foliage, some services begin to scale back in late September.
