It is a gloomy park with unreliable weather and trail conditions. There is often fog, light rain and high humidity. In July and August, it can be very hot (even dangerously hot), especially high up on bare mountain tops but still, it can be extremely muddy and buggy at the same time. Suddenly, it can cool down and become uncomfortable in the evenings and very cool at night.
There is a good chance to see wildlife, enjoy breathtaking lookout views and experience challenges of uphill hiking on a rocky terrain.
There is a section of the International Appalachian Trail winding through the park West to East. But beware of the western part... It is very isolated, muddy and buggy in summer and doesn't offer any great views just the challenge of hiking in the mud.... I would not recommend going anywhere west of Cascapedia: don't waste your time and energy.
Staying on a campsite and enjoying day hikes while exploring different sections of the park is probably the best option and the safest.
