How to plan a 10-day Portugal road trip

Focus on a 4-stop loop starting and ending in Lisbon to minimize travel fatigue. Spend 3 days in Lisbon, 2 in the Douro Valley, 3 in Porto, and 2 in the Algarve before returning to Lisbon.

Secure your rental car. Rent a compact car in Lisbon upon arrival. Ensure it has an 'Via Verde' toll transponder included, as Portuguese highways rely heavily on electronic tolling.
Map your route. Head north from Lisbon to Porto via Coimbra, spend time in the Douro Valley, then drive south along the Alentejo coast to reach the Algarve before looping back to Lisbon.
Book accommodation by hub. Book two main bases: one for the northern leg (Porto) and one for the southern leg (Algarve). Move locations only when necessary to maximize sight-seeing time.
