Hidden Lake Overlook Trail is located at Logan Pass. To reach the pass, drive scenic Going-to-the-Sun Road: 32 miles from the West entrance of the park (the most spectacular portion of the road, in my opinion) or 18 miles from St. Mary entrance on the East side. During July and August, the parking lot at Logan Pass becomes crowded, filling up by 8 a.m. Go early or late to avoid the crowds. Take the park shuttle if it is running. Always check current conditions in the park, before setting out.
