Lizarrusti-Lareo route includes the route between the “Parketxe Lizarrusti” and Lareo swamp. The “Parketxe Lizarrusti”  is located in the port of Lizarrusti, border between Gipuzkoa and Navarra. The parketxe is witness to the border, and said building was once, the headquarters of the Mikeletes. The tour is very comfortable. Of course, being a mountain route, it has small slopes but it has not any difficulty. The tour begins in a leafy beech, and continues along the track that becomes a path until you reach the waterfalls of the Maizi River. The land that was previously beech, becomes a land with a huge diversity of flora: oak, ash, linden, hawthorn, etc. You can see a beautiful landscape towards Berreno. We will continue the ascent towards the swamp, leaving behind the tunnel carved in the rock of Akerreta and the Maizi river, passing first through the quarry from which the construction material was extracted and through the retaining wall of the swamp later. Thus we will arrive at the Lareo swamp. We can surround it with a hike of approximately 1 kilometer. It is a place among the mountains that will surely make you fall in love forever.
