America’s national parks are living classrooms of the planet: geysers and bison in Yellowstone, sheer granite cliffs in Yosemite, red-rock amphitheaters in Utah, and alpine lakes in Glacier.
If you’re searching for the best national parks to visit in the U.S., the answer often depends on when you plan to travel. Seasons dramatically shape the experience — from roaring waterfalls in spring to golden aspens in fall.
Below, we highlight a curated list of national parks Collette visits on tour, organized by the seasons when they truly shine.
Collette’s U.S. national park tours operate primarily from spring through fall (with departures running through October). These are the parks that offer the best experiences during that window.
Spring is one of the most rewarding times to visit national parks in the western U.S. Snowmelt feeds waterfalls, wildlife becomes more active, and desert landscapes bloom.
Spring brings dramatic contrasts — steaming geysers against lingering snow, active wildlife, and fewer crowds than peak summer.
Snow-capped peaks reflect in thawing lakes, and valley wildlife is especially active.
Spring offers ideal hiking temperatures before summer heat sets in.
Featured Tours:
Summer opens high-elevation roads and hiking trails that remain inaccessible earlier in the year.
Going-to-the-Sun Road reveals alpine scenery and turquoise lakes.
Rocky Mountain National Park
Wildflowers blanket subalpine meadows, and Trail Ridge Road delivers panoramic views.
Summer provides full access to high-country hiking and iconic viewpoints like Glacier Point.
Summer offers the broadest road access and services, ideal for first-time visitors.
Featured Tours:
Pro Tip: Summer is peak season. Collette handles reservations, park access logistics, and accommodation — allowing you to focus on the experience.
Fall may be the most underrated season to visit national parks. Cooler temperatures and lighter crowds create ideal conditions.
Crisp coastal air and vibrant foliage make early fall spectacular in Maine.
Aspens turn brilliant gold, and elk rut season adds exciting wildlife viewing.
Wildlife activity increases again in the fall, and cooler temperatures make exploring more comfortable.
With summer heat fading, hiking conditions improve significantly.
Featured Tours:
Best for wildlife: Late spring and early fall
Best for hiking high elevations: Summer
Best for fewer crowds: Late spring and September
Best for fall colour: September–early October
