You'll love to hate this trail, but it does put you at a couple nice lakes and the opportunity to make a loop if you go over the top. What you'll hate is how brutally rough and steep this trail is. It looks short and easy on the map, but it destroys hikers, and also contains signs saying not suitable for stock strings. They did throw some switchbacks in the bottom stretches to make you think there was some engineering but then it goes ballistic up, then a mellow stretch over the summit, then straight down again. This roller coaster is worth doing if you want to stay at a sweet ridgetop lake with views, but get a slap in the face while you are shivering from exhaustion and you see a no-campfires sign at Arrow Lake, elevation 7,870'.
Heart Lake is accessible on a short side trail on the way up. It is kind of a nice mosquito haven with some flat camping.
