This campground is smaller and more secluded than the others on the south side of the lake.

DRIVING NOTE: There are two routes to North Arm Campground—one is rugged and one is suitable for RVs and trailers. Recommended Route: From Sandy, Oregon, travel east on Highway 26 for approximately 40 miles to Skyline Road / FS Road 42. Turn right on Skyline Road, and continue south for about 9 miles. Turn right on FS Road 57, and travel west for approximately 3 ½ miles, crossing the dam at Timothy Lake. Take the 2nd right onto FS Road 5810. North Arm is approximately 5 ½ miles from here. Keep right at all intersections—the road becomes FS Road 5890. The campground is on the right.


Proximity to Timothy Lake allows campers to enjoy a variety of water-related recreation, including boating and sailing, as well as swimming, windsurfing and fishing. Anglers can expect a catch of kokanee salmon and a variety of trout, as well as crayfish. This area has wonderful canoeing and kayaking opportunities. A variety of trails are located in the area. The Timothy Lake Trail is popular for hiking, mountain biking and horseback riding. The 12 miles of relatively level terrain loops trekkers around the lake, providing scenic views of the area. It connects to the Pacific Crest National Scenic Trail, a lengthy hike that extends across three states, from the borders of Canada and Mexico. Portions of that trail also lead southwest to Clackamas Lake Campground and a historic site. The Little Crater Lake is only a short hike away. Little Crater Lake is a geologic oddity, possibly formed by artesian water forcing its way through soft, volcanic rock. The beautiful, turquoise water is a wonder to see. The surrounding meadow is a great place for observing birds and other wildlife. The region is ripe for huckleberry picking as well.


The campground offers 14 campsites for tent and RV camping. There are four hike-to campsites available as well. Each site is equipped with a table and a fire ring. Accessible vault toilets and drinking water are provided. A campground host is also available onsite. 

The nearest gas station/convenience store is about 14 miles away, west on Hwy. 26. The nearest grocery store is in Government Camp, about 19 miles away, west on Hwy. 26.
