Redwood in April.

Crowd snapshot.

April runs about 40,600 recreation visits in the five-year mean, roughly 43% of the June peak. The visitor mix now includes more out-of-region travelers, spring-break families, and the first wave of road-trippers working up or down the coast. Easter weekend produces a clear spike, and weekends generally run busier than weekdays, but the park still absorbs April crowds easily. The Drury Parkway, Lady Bird Johnson Grove, and the beaches feel active but never packed. April is the sweet spot where the weather has improved but the summer masses have not yet arrived, one of the better crowd-to-conditions tradeoffs of the year.

Weather snapshot.

The Klamath station averages an April high near 58.7°F and a low near 42.7°F, the first stretch that feels reliably spring-like. Rainfall drops to about 6.6 inches, and clear, bright days become common between the last winter systems. Rivers are still full with runoff, and shaded trails hold some mud, but the drying trend is real. Morning coastal fog appears more often as the season warms. Snow remains absent at the coast. The uplands along Bald Hills Road can be sunny and clear when the coast is gray, a useful trick on a foggy April morning. Overall this is comfortable hiking weather with a low but non-zero rain risk.

Access snapshot.

Roads are open year-round and April's drier weather makes the unpaved drives more reliable, though check the NPS Redwood conditions page after any late storm. Howland Hill and Bald Hills roads are unpaved and no-RV; Davison Road to Gold Bluffs Beach caps RVs at 24 feet with no trailers. The summer Fern Canyon day-use permit does not begin until May 15, so April access there is permit-free. Mill Creek Campground is typically still closed until mid-May; the other state-park campgrounds reserve through ReserveCalifornia. Free Tall Trees trailhead permits are on the NPS Redwood permits page. Redwood National Park is free to enter.

Seasonal events.

April is peak spring in the redwoods. Trillium, redwood sorrel, and rhododendron buds fill the forest floor and understory, while the last northbound gray whales pass the Klamath River Overlook (NPS). Migratory songbirds are back in force along the rivers, and Roosevelt elk are approaching the late-May-through-June calving season, so cows begin to separate from the herds. This is one of the more colorful months in an evergreen park, and the combination of blooming understory, active birds, and passing whales gives April an outsized wildlife payoff. Coastal wildflowers begin along the bluffs, and the tidepools stay productive on the spring low tides.

Audience verdict.

April is one of the first broadly recommended months at Redwood. It serves spring-break families who want low crowds, photographers chasing spring bloom and morning fog, whale-watchers catching the tail of the northbound migration, and road-trippers who want good weather without summer traffic. The unpaved old-growth roads are usually drivable, opening up Howland Hill and the Tall Trees approach. RV travelers can use the year-round campgrounds, though Mill Creek may still be closed until mid-May. For a visitor weighing weather, wildlife, and crowds together, April delivers close to the best all-around value of the year, second only to the September window.

Common questions.

Is April a good time to visit Redwood?

April runs moderately busy at Redwood, about 43% of the June peak, with mild shoulder-season weather (average highs near 59°F). Crowds sit in the middle of the year, neither peak nor empty.

How crowded is Redwood in April?

April averages about 40,599 recreation visits, roughly 43% of Redwood's busiest month (June). That lands it in the middle of Redwood's year for crowds.

How much of Redwood is open in April?

In a typical April, about 92% of Redwood's road network (weighted by how important each route is) is open to wheeled vehicles. Road-opening dates shift year to year, so check the official NPS page for current conditions before you go.

Methodology

Monthly recreation visits come from the official NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats; the statistic shown is Recreation Visits (Redwood National Park), the 5-year mean across 1979-2025. These counts cover Redwood National Park (the NPS-administered lands); the three cooperatively managed California state parks are counted separately, and the 2024-2025 totals reflect an improved NPS counting method rather than real growth, so the reliable timing signal is the month-to-month share of the peak. Climate normals come from NOAA NCEI's 1991-2020 U.S. Climate Normals at Klamath, CA (station USC00044577, 28 ft elevation, coastal lowland). The access score weights how much of the road network is typically drivable that month; Redwood's roads are open year-round, so the winter dip reflects storm closures on the unpaved drives. Year-variable specifics (the Gold Bluffs Beach / Fern Canyon permit window, Mill Creek Campground season, elk rut and calving, gray whale windows) drift year to year and are hedged above; confirm current details on the official NPS Redwood page before booking.
