Redwood National and State Parks protect a patchwork of ancient coast redwood groves, wild Pacific coastline, and open prairies along Northern California's far north coast. The park system spans nearly 132,000 acres across one national park and three state parks, sheltering some of the tallest trees on Earth, herds of Roosevelt elk grazing in fog-draped meadows, and fern-walled canyons that feel prehistoric. From the towering old-growth giants of Stout Grove and Tall Trees Grove to the dramatic tidepools along Enderts Beach, this is a place where the forest, the coast, and the wildlife coexist in a way you won't find anywhere else in the country.
The best time to visit Redwood National Park falls into two windows: mid-March through mid-May and late September through mid-November, except for a couple of stretches in October when conditions can dip. Spring brings lush wildflowers, rhododendron blooms, active elk calves in the meadows, and the tail end of gray whale migration along the coast, all with manageable crowds and comfortable hiking temperatures. Fall delivers some of the clearest skies of the year, dramatic elk rut displays at Elk Prairie and Gold Bluffs Beach, and the first salmon returning to coastal creeks. If you can only pick one window, spring edges ahead thanks to longer daylight hours and the sheer beauty of the forest floor in bloom. Summer works as a secondary option for those who want the driest trails and full access to Fern Canyon, but it comes with significantly more visitors and inland heat that can push well past 90°F.
Spring in Redwood National Park, the United States
The forest floor comes alive in spring. Creeks run full from winter rains, sword ferns unfurl across the understory, and the park's famous pink rhododendrons begin blooming in late May, creating vivid contrast beneath 300-foot canopies. Afternoon highs average 78.2°F (25.7°C), warm enough for comfortable all-day hikes but not punishing. This is also calving season for the park's Roosevelt elk: look for newborns at Elk Prairie and along the Newton B. Drury Scenic Parkway from late April through May. Gray whales are still migrating northward in March and April, and you can spot spouts from the Klamath River Overlook or High Bluff Overlook without needing binoculars.
Showers remain infrequent, with roughly one to four wet days per month, though mornings can start cool at 54.2°F (12.3°C) before the sun warms the groves. Pack layers you can peel off by midday, and keep a light rain shell handy for the occasional drizzle. Spring is the second busiest season, but crowds stay well below summer levels, and you'll find that trails like Damnation Creek and Boy Scout Tree still feel remarkably quiet on weekdays. The Avenue of the Giants Marathon typically takes place on the first Sunday of May, so plan around that date if you're heading south to Humboldt Redwoods State Park.
Tall Trees Grove is particularly rewarding in spring, when the surrounding creek is still flowing strong and the trail is less competitive for the required free permit. Long daylight hours, with the sun not setting until nearly 8pm by late May, give you plenty of time to combine a morning grove hike with an afternoon of tidepooling at Enderts Beach.
Summer in Redwood National Park, the United States
Summer is when the park sees its heaviest visitor traffic, and for good reason: trails are dry, unpaved roads like the route to Fern Canyon are fully accessible, and ranger-led programs run at their fullest schedule, including guided kayak tours on the Smith River. Fern Canyon itself, with its 50-to-80-foot walls draped in five species of fern, requires advance reservations from mid-May through mid-September. Coastal fog is a defining feature of this season, rolling in most mornings and creating the dramatic shafts of light that photographers prize in the groves. By afternoon, the fog often burns off inland, but highs average 92.8°F (33.7°C), so the coast offers natural relief.
Early to mid-August brings the hottest stretch, with highs reaching 95.3°F (35.2°C) and overnight lows of 72.5°F (22.5°C), making inland trails less comfortable during midday. Precipitation drops to its lowest levels, with roughly two to four wet days across the whole season. Plan to hike early in the morning or late in the afternoon when temperatures are gentler and the light filtering through the canopy is at its most magical. Stout Grove in Jedediah Smith Redwoods is famous for its late-afternoon golden light around 4pm in summer, and the experience is worth timing your day around. Accommodation costs run higher than usual this time of year, and campground reservations at Elk Prairie and Gold Bluffs Beach fill up weeks in advance.
Lows still dip to 70.1°F (21.1°C) on average, so evenings by the coast are pleasant for campfire cooking or stargazing. Mosquitoes can be persistent in the groves from June through August, so bring insect repellent, especially for shaded creek-side trails. Long June days stretch past 8pm, giving you over 14 hours of daylight to split between forest hikes and coastal exploration.
Fall in Redwood National Park, the United States
After Labor Day, the crowds thin dramatically and the summer fog lifts to reveal some of the clearest, crispest days of the year. September and October often bring the park's most consistently sunny weather, and this is the season for one of its great wildlife spectacles: the Roosevelt elk rut. Bull elk with massive antlers spar and bugle across Elk Prairie and Gold Bluffs Beach from September through November, an event you can watch safely from designated viewing areas, though you should stay at least 100 feet away. By late October, bigleaf maples and vine maples add splashes of gold and orange against the evergreen redwood canopy.
Highs average a comfortable 79.1°F (26.2°C), while mornings cool to 52.7°F (11.5°C), perfect layering weather for a dawn start on the trail. Rain remains infrequent, with one to three wet days per month, though November sees precipitation begin to pick up. Salmon start returning to the Klamath River and coastal creeks in October, attracting bald eagles and river otters to the waterways. Tourism volume drops noticeably this season, and accommodation prices follow. You can often secure last-minute campsites and explore trails like the James Irvine Trail or Lost Man Creek without seeing another person.
Whale migration picks up again in November, with gray whales heading south past the Klamath River Overlook and High Bluff Overlook. As daylight shortens to about 10.5 hours by November, plan your hikes for morning and save coastal overlook stops for the softer afternoon light. Bring a waterproof layer for the occasional shower, and consider waterproof boots if you're heading into creek crossings after the first fall rains.
Winter in Redwood National Park, the United States
Winter transforms the redwoods into their moodiest, most atmospheric version. Swollen creeks carve through the old-growth groves, fog clings to the trunks, and you'll likely have entire trails to yourself. This is the quietest season by far, with visitor numbers at their lowest in January. Some unpaved roads, including the route to Fern Canyon, may close during periods of heavy rain, and the Jedediah Smith campground store shuts down for winter. Visitor center hours are limited, and restaurant options in nearby Crescent City and Orick are reduced.
Highs average 60.6°F (15.9°C) and lows drop to 38.3°F (3.5°C), with occasional light snow possible at higher elevations in late January. Expect one to three rainy days per month, and prepare for muddy, slippery trails. December is one of the wettest months, and the short days, only about 10 hours of daylight, mean less hiking time. That said, winter has its rewards: gray whale migration peaks between December and March, visible from coastal bluffs, and storm watching at High Bluff Overlook as Pacific swells crash into sea stacks can be breathtaking. Roosevelt elk remain visible in lowland meadows, and the forest's greens look impossibly saturated after a good rain.
If you visit in winter, pack serious rain gear, waterproof boots, and warm layers for mornings that hover around freezing. The Newton B. Drury Scenic Parkway hosts monthly Hike and Bike days from October through May, giving you car-free access to the road on the first Saturday of each month.

Travel Tips & Safety for Redwood National Park, the United States
Redwood National Park is remote. The nearest commercial airports are in Arcata (ACV) and Crescent City (CEC), both small regional fields. Most visitors drive in on Highway 101, which runs the length of the park system. Cell service is unreliable throughout the parks, so download offline maps and confirm trail conditions at a visitor center before heading out. The park itself charges no entrance fee, though some state park areas, including the road to Fern Canyon and Gold Bluffs Beach, require a day-use fee or seasonal reservation.
Pack layers regardless of season: the coast can be 20 to 30 degrees cooler than areas just a few miles inland, and fog can roll in without warning. Bring waterproof footwear for creek crossings and wet trails, and carry bear canisters or use proper food storage if camping, as black bears are present throughout the park system. Keep a safe distance from Roosevelt elk at all times, especially during fall rut when bulls are aggressive.
