From Bellingham, drive east, away from downtown on often busy Lakeway Drive (I-5 exit # 253). Follow the curvy main road which eventually becomes Cable Street. As it descends the last hill (Lake Whatcom in sight ahead) turn right onto Austin Street; this is the first right turn after the well marked pedestrian crossing. After a stop-sign, the street becomes Lake Louise Road. In about 1.5 miles look for the large trailhead parking lot on the left; be cautious of traffic when turning in. A WTA bus stop is also located directly across the road from the parking lot. Some Sudden Valley residents use the small second entrance to the Reserve located near the top of High Cliff Lane.
