Hot take: backpacking isn't as good as people say
The complete guide to budget travel in Portugal in 2025, acknowledging the Lisbon and Porto tourism inflation.
Lisbon accommodation reality: the hostel dorm explosion of 2014-2018 has flattened into a mature market where dorms cost €18-28/night in central locations. The party hostel wave peaked; the good boutique hostels remain at similar prices. The sub-€15 dorm largely doesn't exist in central Lisbon anymore.
The accommodation strategy that works: Intendente, Mouraria, and Almada (across the river) neighborhoods have cheaper accommodation than Baixa-Chiado and Alfama. Book 2-3 nights and then look for weekly rentals directly through the hostel or via a room-share app.
Food in Lisbon: the prato do dia at a traditional tasca (not on the main tourist streets) costs €8-10 for a full meal with bread, wine/water, and coffee. This is the correct way to eat in Lisbon. The tourist restaurants in the Alfama with fado music attached charge €15-25 for the same quality. The Mercado da Ribeira food hall is overpriced but convenient.
Outside Lisbon and Porto: the interior Portugal (Alentejo, Beira Interior, Trás-os-Montes) has accommodation and food costs 30-40% below the coastal cities. The small towns have excellent regional food, better access to authentic daily life, and zero tourist premium.
Sintra day trip: €4.30 train return, free to walk between the palaces, individual palace entry €14-17. The National Palace (in town, cheapest at €10) is worth one palace; the Pena Palace is the most photographed. Pick one, skip the others on a budget.
