Trail shared with hikers and birdwatchers. Be careful and respectful.
Take the narrow, but clean trail up towards the Serafina viewpoint. From there, it's a bit farther uphill before descending on a single trail with some rocks and roots to the ruins of the Serafina coffee plantation. From here, it is a rolling trail through the forest which gradually turns into a dirt road and leads you back to the main street along the lake. Short, but nice and easy, and you could do the Cafetal Buenavista straight after it.
