Serpentine trail is probably the most difficult climb on the Tamarancho loop, especially on a hot day. It starts out in the open, and descends through some meadows. There is a small rock drop marked with a double black sign, although it does not really deserve that rating, there is a blue sign next to a rocky ride around. It enters some trees, with very challenging and rocky climb marked with a red sign, or an easier climb marked with a blue sign. The climb seems to keep going and going, and you can really work up a sweat on a hot day.
