Forget the summer gridlock. The real story of America’s national parks is told in September and October, during the “secret season.” This is when the crowds disappear, the weather is perfect and the landscapes transform. The post-Labor Day slump is a traveler’s dream. With schools back in session, parks like Zion, Yellowstone and the Grand Canyon are no longer at peak capacity. This means a more intimate and enjoyable experience. The intense summer heat subsides, making hiking and outdoor activities not just possible, but genuinely pleasant. Think crisp, cool air and golden sunshine. Wildlife, in general, is more active in the cooler temperatures, providing unparalleled viewing opportunities. Here are a handful of great national park vacation ideas.

1. Saddle and Paddle Yellowstone: Flying Pig Adventures’ three-night Yellowstone tour gives guests the opportunity to experience the park like never before.
