Is a rail pass worth it for exploring Portugal’s main cities and the Algarve?

Portugal’s train network is efficient but relatively inexpensive; a Eurail Portugal pass often costs more than buying point‑to‑point tickets, especially if you book combo or advance fares on CP. For trips like Lisbon‑Porto, Lisbon‑Faro, or Porto‑Vigo, buying individual tickets is usually cheaper unless you plan many day trips.
