Azores Walking Tours Worth Your Boots
The Azores’ official trail network is graded and marked well enough that you could plan a week here around trail codes alone: PR04 in the morning, PRC09 after lunch, and never once ask a stranger for directions.
The trail system, briefly
The Regional Directorate of Tourism’s Trilhos dos Açores program marks every certified route as either PR (Pequena Rota, short, yellow-and-red markers) or GR (Grande Rota, long, red-and-white markers). Every one of them has a downloadable GPS track and an information board at the trailhead.
Best for the classic postcard: PR04 SMI, Sete Cidades
Twelve kilometers, about 3.5 hours, following the caldera rim between hydrangea hedges to a series of viewpoints over Lagoa Azul and Lagoa Verde. Verdict: if you only walk one trail in the Azores, this is the one, and it’s popular for good reason rather than in spite of one.
Best for a hidden payoff: PRC09 SMI, Salto do Prego and Sanguinho
A 4.5-kilometer loop out of Faial da Terra climbs through dense subtropical forest to the secluded Salto do Prego waterfall, then loops back through Sanguinho, a stone hamlet that was fully abandoned before being restored. Verdict: the best trail here for travelers who want a waterfall without the crowds of the bigger caldera hikes.
Best for a genuine leg-burner: PRC06 SMI, Rocha da Relva
A steep 5.5-kilometer, 2.5-hour descent down a 300-meter cliff on a switchback cobblestone path ends at an isolated, vehicle-free seaside village where cargo still arrives by donkey rather than by road. Verdict: the toughest trail on this list, and the one that feels most like discovering somewhere the rest of the island has forgotten.
Best for no hiking boots at all: Ponta Delgada’s historic core
A flat walk through the triple-arched 18th-century Portas da Cidade gate, past the black-and-white facade of Igreja Matriz de São Sebastião and the baroque Nossa Senhora da Esperança convent, ending at the Mercado da Graça market. Verdict: the right choice on a travel day or a rest day between two harder hikes, not a substitute for the caldera trails.
What to check before any of these
Before driving up to Sete Cidades or Lagoa do Fogo for a trailhead start, check the SpotAzores webcams at spotazores.com; both sit high enough that a clear coastal morning can still mean fog at the rim. None of these trailheads are reachable by public bus, so build in a rental car for the drive. For the hot springs and viewpoints these same trails connect to, see the Azores attraction tours guide .
Check the webcam the night before, not the morning of. An early departure gives you no time to switch to a different trail if the crater rim turns out to be socked in.
