The reservation season for the 2025 summer season for the Hoh campground is June 13, 2025 - September 8, 2025.

Important information about booking windows: To better serve visitors, Hoh Campground will be releasing campsites in a series of three staggered block releases by loop. These block releases will be 6 months in advance, two weeks in advance, and 4 days in advance. 

• A loop campsites will be available for reservation 6 months in advance.

• C loop campsites will be available for reservations two weeks in advance.

• B loop campsites will be available for reservations 4 days in advance.  

Outside the reservation season, Hoh Campground is open for camping on a first-come, first-served basis. Some campsites may be closed during winter.  

The Hoh Rain Forest, pronounced "Hoe", earns its name from the ever-flowing Hoh River that carves its way from Mount Olympus towards the Pacific Coast. However, where the name originates, is up for debate. The word "Hoh" undoubtedly comes from Native American languages; possibly the Quileute word "Ohalet" which means "fast moving water" or "snow water." Since the river itself forms from glacial runoff, that origin seems straightforward. Other explanations state that the Quinault word "Qu," meaning "boundary," could be the root of the name as a river as massive as the Hoh certainly forms a formidable boundary across the landscape. A third consideration claims that the word "Hoh" translates to "man with quarreling wives." What the actual history behind the name is, appears to be lost to time. 

Regardless of the name, there's no question as to the allure that draws visitors back to the rainforest year after year. Throughout the winter season, rain falls frequently in the Hoh Rain Forest, contributing to the yearly average of 140 inches (3.55 meters) of precipitation each year. The result is a lush, green canopy of both coniferous and deciduous species. Mosses and ferns that blanket the surfaces add another dimension to the enchantment of the rainforest.
