Just north of Mão is a stunning 3-hr section of the GR223 that goes through s'Albufera Natural Park from the lighthouse to the quaint white-washed town of Es Grau by the sea. This section capped off our trekking on the GR223. There are a number of natural coves and beaches, so don't forget your birthday suit!
Trail note: Accommodations are scarce or non-existent in this area but pickup at many trailheads in northern Menorca is available by taxi (and/or bus during summer.) So this part does not work as well for inn-to-inn trekking.
