The trail begins at the Miradouro da Vista do Rei (Kings’ Belvedere), a postcard location, the name of which was derived from the fact that King D. Carlos and Queen D. Amélia visited it on July 6th of 1901.
After appreciating the view, you will find to the left of the Belvedere an information panel concerning the trail. Consult the map of the trail and continue walking on the dirt road ahead of you. At the beginning of the trail, you will see, to your right, a steep shortcut. Do not take that route. Stay on the pathway that extends around the edge of the western crater of Caldeira das Sete Cidades.
Surrounded by hedges of Hydrangea macrophylla, a shrub that flowers in June and is found in all islands of the Azores, this trail offers fine views of the crater of Sete Cidades, with its blue and green lagoons on one side and, on the opposite side, beautiful panoramic views of the western coast of the island.
Approximately 3.5 km into the trail, a descending detour will appear on your left. Ignore it and stay on the same dirt road until you reach the intersection the regional road that connects the village of Mosteiros to Sete Cidades.
At that same intersection, a few metres to the left, you can also appreciate the magnificent view of the village of Mosteiros and its islets from the Belvedere of Lomba do Vasco.
Continue by taking a right, choosing the regional road, descending towards the village of Sete Cidades. Walk a further 600 metres and you will find a dirt road on your left. Advance for a few minutes along that pathway, until you find the intersection of this trail with trail PR4 SMI Mata do Canário - Sete Cidades. Take a right on the shortcut known as Arrebentões, heading towards the village, passing by a small water tank, used to quench the thirst of the cattle that abounds here. A part of this trail is steep. We recommend caution against slipping hazard whilst descending.
The trail leads to the margin of Lagoa Azul (Blue Lagoon). Follow the pathway that surrounds the margin of the lagoon until you find the Store of the Park of Lagoa das Sete Cidades. We recommend that you visit an area dedicated to the geological/biological interpretation and promotion of the Natural Park of São Miguel.
