also in the front range, there's a buttload of falls in RMNP. bridal veil, timberline, and lost falls are all really cool and less crowded if you want something with a hike. if you wanted to do multiple calypso cascade and ouzel falls are on the same hike and could be combined with something higher up if you're feeling saucy. the big thing with rocky to remember, if you hike more than 3 miles you'll see little to no traffic with the exceptions of flattop mountain and longs peak, heck on the less popular trailheads, anything longer than 2 will get you that nice secluded feeling. also, big one...the bear lake trailhead is nuts on summer weekends, if you can't get there before 7am then you should scrap your plans for something else.
