Redwood in May.

Crowd snapshot.

May runs about 65,000 recreation visits in the five-year mean, roughly 68% of the June peak and the month the crowd curve turns steep. The visitor mix broadens to full summer variety: families, international road-trippers, campers, and photographers. Memorial Day weekend at month's end is the first genuinely busy stretch of the year, with campgrounds full and the Fern Canyon corridor near capacity. The first three weeks stay more manageable, with weekday traffic still easy in the groves. May is the hinge between the quiet shoulder and the summer plateau; time it early in the month and you get near-summer access with spring-level crowds.

Weather snapshot.

The Klamath station averages a May high near 61.2°F and a low near 46.5°F, mild and increasingly dry, with rainfall down to about 3.6 inches. The defining new feature is fog: cool, damp coastal mornings that often burn off to clear afternoons, the pattern that will hold through summer. Rivers begin dropping from their runoff peak. Snow is absent at the coast. The uplands along Bald Hills Road climb above the fog and can be markedly sunnier and warmer than the coast on a foggy morning. May weather is comfortable for hiking, with long daylight and a low rain risk, though a cool, gray coastal morning is common and worth dressing for.

Access snapshot.

May brings the summer access systems online. The Gold Bluffs Beach / Fern Canyon day-use permit is required beginning May 15 and can be reserved up to 24 hours ahead; a Prairie Creek state-park day-use fee also applies to drive Davison Road, which caps RVs at 24 feet with no trailers. Mill Creek Campground typically opens by mid-May; all four developed campgrounds reserve through ReserveCalifornia with no first-come sites. The unpaved Howland Hill and Bald Hills roads are usually dry and open. Confirm current status on the NPS Redwood conditions page. Redwood National Park charges no entrance fee.

Seasonal events.

May is Roosevelt elk calving season, which runs late May through June. Cows separate to give birth and are protective, so NPS urges extra distance beyond the usual 25 yards, especially at Elk Meadow, Prairie Creek, and Gold Bluffs Beach. Rhododendron and azalea bloom brightens the understory along the Drury Parkway and Howland Hill, a signature late-spring show in the old growth. Migratory birds are nesting, and the last northbound gray whales trail off the coast. Wildflowers peak along the coastal bluffs. The combination of elk calves, blooming rhododendrons, and long daylight makes May one of the most rewarding wildlife-and-scenery months, just as the crowds begin to build.

Audience verdict.

May serves a broad audience: families before the school-out rush, photographers chasing rhododendron bloom and fog, and campers who want full operations without full-summer crowds. The elk calving season adds a wildlife draw but demands caution around protective cows. Time the first three weeks for the best balance; Memorial Day weekend is the year's first sellout, so book campgrounds through ReserveCalifornia well ahead. RV travelers get more options as Mill Creek opens, but the best old-growth drives stay unpaved and length-limited, so plan to day-trip them in a car. For a visitor who wants spring wildlife with near-summer access, May, early in the month, is an excellent choice.

Common questions.

Is May a good time to visit Redwood?

May runs busy at Redwood, about 68% of the June peak, with mild shoulder-season weather (average highs near 61°F). It is one of the busier months, though not always the single peak.

How crowded is Redwood in May?

May averages about 64,976 recreation visits, roughly 68% 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 May?

In a typical May, about 98% 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.
