Dream Lake is the third lake in a series of 4 lakes for a day hike.  You start at Bear Lake, which is handicap accessible, and go from Bear up to Nymph, on to  Dream and end at Emerald Lake.  The lakes are pretty at all stopping points and you can lunch on any of the rock outcroppings that you can find nearby to the lakes.  These hikes are not particularly strenuous except for the altitude gain that many people are not acclimated for in Rocky Mountain National Park.  It's beautiful scenery and it's not required to hike to all four lakes.
