Beautiful views abound and the hike is pleasant and fairly easy. This trail is good for children and dogs and highly recommended for all skill levels, even though there are a few minor climbs. In June and July the trail may still have some snow and ice at some points, as well as snow near the mouth of Long Lake. The hike begins by ascending on gentle grades along the west side of Rock Creek. The grade steepens a bit as the trail climbs a small hill above Mack Lake. The lake is sweetly tucked below the trail in a gully but is a little difficult to see from the trail. Soon the views will open up and the sights of the high granite peaks are absolutely wonderful: Mt. Morgan, Pyramid Peak, Bear Creek Spire, Mt. Abbot, Mt. Dade, and Mt. Starr. The trail will then wander through a gentle rolling landscape of meadows and scattered pine forest as the views keep getting more and more stunning. Before finally reaching the picturesque Long Lake, there are lovely views of the glistening waters of Heart lake and Box Lake. Keep in mind that while the 2 mile trek to Long Lake is not a difficult one, this is still a high altitude hike - over 10,000 ft. - and it can often be felt in the head and lungs. This is a serene, rewarding little adventure.
