Remember, Longwater and Hackett are closed at the Teller/Park County lines. Hackett is hard to tell where the closure is (top of big hill where the trail splits) Longwater has a post and cable. Metberry is the only trail open all the way to the river. Doing all three is possible, but depending on how close you are to leaving, you'll do the last one in the dark.
Have fun and be safe!
