| Visitation season: | The primary visitation season is summer, however there are reasons to visit in any season. Winter rains (65 inches or more a year) keep visitation low. In the spring, wildflowers are an especially beautiful attraction. The colorful leaf displays make fall a nice time to visit as well. |
| Campgrounds: |
|
| Day Use areas: | Day use areas are open from dawn until dusk all year. There is a $2 day use parking fee to use Williams Grove or Federation Grove. No overnight camping is allowed in day use areas. |
| Trails: | All trails are open year-round. Some backcountry trails may be difficult to access in the winter. Seasonal bridges over the Eel River are removed in winter. Although the trails on the opposite side of the river are open, the hike in is much longer. Winter access is available at the Big Tree Area or Grasshopper Fire Road from the Mattole Road. |
| Seasonal Bridges: | Seasonal bridges over the Eel River and Bull Creek are usually removed by mid-September. The bridges generally are installed by Memorial Day. These temporary bridges cannot be left in year-round due to seasonal water level changes in the Eel River and its tributaries. |
