San Agustín is something of a random starting point but it’s as good as any, I suppose. More likely you’ll approach from the CA-2 and then head north. You approach the pleasant mountain town of Berlin after an enjoyable meander of 15 km, which will take three quarters of an hour. “Happiness” – that’s what Alegría means in English – is only another 7 km further on. From the town, the lagoon of the same name is just over 2 km of descent on an unpaved road that veers south out of town.
