About North Arm (Timothy Lake) Campground
Tucked away on the northeastern shore of Timothy Lake, North Arm Campground offers a peaceful retreat in the heart of Mt. Hood National Forest. This intimate camping destination features 18 thoughtfully spaced sites, where 14 traditional campsites welcome both tent campers and RV adventurers, while 4 exclusive hike-in sites reward those seeking an even deeper connection with nature. Here, towering conifers create natural privacy screens between sites, and the gentle lapping of lake waters provides a soothing soundtrack to your wilderness escape. Miles of nearby trails beckon hikers to explore the surrounding forest, making this hidden gem a perfect basecamp for outdoor enthusiasts seeking tranquility away from the crowds.
The campground provides a mix of camping options, including standard tent and RV sites, as well as hike-to sites.
Historical SignificanceThe story of North Arm Campground is forever linked to the creation of Timothy Lake in 1956, when the Oak Grove Hydroelectric Project transformed this valley into one of Oregon's most beloved mountain recreation areas. This engineering marvel not only provided renewable energy but also created a stunning 1,400-acre playground for generations of outdoor enthusiasts. Just a short drive away, history buffs can explore the Clackamas Lake Ranger Station, a rustic outpost dating back to the early 1900s that stands as a testament to the Forest Service's century-long stewardship of these lands. These historic sites offer fascinating glimpses into how humans have worked to both harness and preserve the natural beauty of Mt. Hood's forests.
Weather and SeasonsEach season paints North Arm Campground with its own distinct palette. Summer brings warm, sun-drenched days perfect for lake activities and evening campfires under star-filled skies. As autumn arrives, crisp mornings give way to comfortable afternoons ideal for hiking and wildlife watching. Winter transforms the landscape into a snow-dusted wonderland, though freezing temperatures and heavy snowfall may limit access during these months. Spring emerges with occasional rain showers that awaken the forest floor, bringing wildflowers and the promise of another spectacular camping season. Visitors should come prepared for mountain weather's quick changes, especially during shoulder seasons when temperatures can swing dramatically between day and night.
ElevationPerched at 3,400 feet above sea level, North Arm Campground occupies that sweet spot where mountain air stays refreshingly cool even during summer's peak, offering welcome relief from valley heat. This elevation creates an ideal climate for comfortable camping from late spring through early fall, with daytime temperatures typically ranging from the 60s to low 80s during summer months. The altitude also means winter arrives early and lingers late, often blanketing the campground in snow from November through April. This elevated position not only provides natural air conditioning but also contributes to the area's diverse ecosystem, supporting everything from towering Douglas firs to delicate wildflowers that thrive in the mountain environment.
Natural Features and SceneryNorth Arm Campground immerses visitors in a living postcard of Pacific Northwest beauty. Ancient conifers stretch skyward, their massive trunks creating cathedral-like groves that filter sunlight into dancing patterns on the forest floor. Timothy Lake sparkles through the trees, its pristine waters reflecting the surrounding peaks and offering endless opportunities for contemplation or recreation. Nearby wetlands serve as natural amphitheaters for wildlife viewing, where patient observers might spot deer coming to drink at dawn or hear the haunting call of loons across the water. When summer arrives, the understory bursts with huckleberry bushes heavy with fruit, inviting campers to enjoy nature's bounty. On clear days, breaks in the forest canopy reveal stunning views of Mt. Hood's snow-capped summit, a majestic reminder of the volcanic forces that shaped this remarkable landscape.
Geological RegionNorth Arm Campground sits within a geological wonderland shaped by volcanic activity and glacial forces over millions of years. Located on Timothy Lake's northeastern shore, the campground occupies land carved by ancient glaciers descending from Mt. Hood, Oregon's highest peak and most recently active volcano. The surrounding Mt. Hood National Forest encompasses diverse geological features, from volcanic deposits to glacial moraines, creating the varied topography that makes this area so visually striking. The 1,400-acre Timothy Lake itself fills a natural basin enhanced by human engineering, surrounded by dense conifer forests that have reclaimed the landscape following historic volcanic events. Wetland areas near the campground represent nature's ongoing work, where streams and springs continue to shape the land, creating crucial habitat for diverse wildlife while adding to the area's scenic beauty.
