The route starts in the forest reserve and recreation park of Mistério de São João and crosses the broken lava fields — the "mistérios" — left by the eruptions of 1718 and 1720, ground so strange to islanders at the time that it gave the area its name.

Along the way you pass old tide wells at Baía do Arruda, Ponta do Admoiro, Verdoso and Maré do Rego, the restored Ponta Rasa windmill from 1949, and the Casa do Pico and "O Alvião" museum, where you can learn about the island's traditional farming families and São João cheese.

The coast itself offers several natural pools — Ponta do Admoiro and the bathing spots of Arinhas and Fonte are worth a swim if you have time — before the trail passes the Império do Espírito Santo and the churches of São João and São Bartolomeu, finishing in Silveira.

At 8.5 km and about 3 hours, with roughly 450 m of climbing spread across the lava fields, the effort is moderate for an "easy"-rated route — budget time for the museum and a swim rather than rushing it.

Official facts, our words

What to know

Start & finish
Mistério de São João Forest Reserve to Church of São Bartolomeu, Silveira
Safety
The lava-field sections underfoot are rough and uneven, and the trail runs through a protected habitat area for coastal wildlife, so keep to the marked path and take care at the natural pools if the sea is up.
When to go
The natural pools along the coast are most inviting in calmer summer seas; the lava-field stretches can be greasy after rain.
