For 14–17 October 2026 (Wednesday–Saturday), I'd structure the trip around historic Lisbon + Belém + one full day in Sintra. Since you're vegetarian, I'd deliberately put several strong vegetarian/vegan restaurants into the route rather than relying on finding vegetarian options at traditional Portuguese places.

I'm assuming 14 October is your first full/mostly full day and 17 October is usable until late afternoon. No car needed.

## Day 1 — Wed, 14 Oct: Baixa, Chiado & Alfama

Morning — Baixa & Chiado. Start around 09:30 at Praça do Comércio and walk north: Praça do Comércio, Rua Augusta, Arco da Rua Augusta, Rossio, Praça da Figueira, Convento do Carmo, Chiado, Elevador de Santa Justa — see it from outside; I wouldn't spend time queuing unless you specifically want to ride it. Have coffee/pastry somewhere around Chiado.

Lunch: Organi Chiado — excellent fit for your trip and entirely vegan.

Afternoon — Alfama. Walk through: Sé de Lisboa, Miradouro de Santa Luzia, Portas do Sol, Alfama's narrow streets, Castelo de São Jorge. The castle is open 09:00–21:00 in October, so you don't have to rush. Adult admission is currently €15. [Visit Lisboa] I'd aim to reach the castle around 16:00, then stay for the late-afternoon views.

Sunset: Miradouro da Senhora do Monte. Dinner: Plant Base in Chiado — vegan, central and a good first-night dinner. Walking: ~10–12 km.

## Day 2 — Thu, 15 Oct: Belém + LX Factory

This is your west-Lisbon day, so don't combine it with Alfama. 09:00 — Head to Belém by tram/bus from central Lisbon. Visit: 1. Jerónimos Monastery (~1–1.5 hours). 2. Pastéis de Belém — the famous custard tart is vegetarian, although obviously not vegan. 3. Padrão dos Descobrimentos, walk along the waterfront. 4. Belém Tower — open 09:30–17:30, last entry 17:00. [Visit Lisboa]

13:30–14:30 — Vegetarian lunch: Sabor Superior if you want something casual, or return toward central Lisbon. 15:00 — MAAT / waterfront. 17:00 — LX Factory, ~2 hours.

Evening: return to Chiado/Baixa. Dinner: Jardim das Cerejas — inexpensive vegan Portuguese-style food, Chiado. Alternative: Legumi Sushi Vegan.

## Day 3 — Fri, 16 Oct: Sintra day trip

Sintra is much more worthwhile than trying to squeeze Cascais into a four-day Lisbon trip. The train from Rossio → Sintra takes ~40 minutes, with frequent services. [Visit Sintra]

08:15 — Rossio Station, train to Sintra, arrive ~09:00. 09:30–12:00 — Pena Palace via bus 434. The official October schedule has the park 09:00–19:00 and palace 09:30–18:30, with timed admission. Adult Essential Visit tickets are currently €20. [Parques de Sintra] Book your Pena Palace time in advance; 2–2.5 hours.

12:30 — Lunch in Sintra: look for a vegetarian/vegan option around the historic centre. 14:00–16:00 — Quinta da Regaleira (Initiation Well, tunnels, gardens). In October, Regaleira's current schedule is 10:00–19:30, last entry 17:30. 16:00–17:00 — Sintra old town: coffee, travesseiro, queijada. 17:00–18:00 — Train back.

Evening: dinner close to your accommodation; Vegan Junkies for a relaxed, inexpensive dinner. Important: I would not attempt Pena + Regaleira + Moorish Castle + Monserrate all in one day.

## Day 4 — Sat, 17 Oct: Graça, Mouraria & final Lisbon

09:00 — Graça: Miradouro da Senhora do Monte, Miradouro da Graça, Igreja da Graça. 10:30 — Mouraria, then Martim Moniz → Rossio → Praça da Figueira. 12:00 — Lunch: Manjerica — vegetarian, convenient around Praça da Figueira. 13:30 — one of: National Tile Museum / Oceanário de Lisboa / a leisurely final afternoon in Chiado. 16:30 — sunset at Miradouro de Santa Catarina. Final dinner: Legumi Sushi Vegan, or Plant Base for Portuguese-style vegan.

## Vegetarian restaurant shortlist

| Restaurant | Style | Level | Best for |
|---|---|---|---|
| Plant Base | Vegan | €€ | Best overall dinner |
| Organi Chiado | Vegan | €€ | Lunch / central |
| Jardim das Cerejas | Vegan | € | Cheap Portuguese-style |
| Legumi Sushi Vegan | Vegan sushi | €€ | Nice dinner |
| Vegan Junkies | Vegan comfort food | €€ | Casual dinner |
| Manjerica | Vegetarian | € | Breakfast/lunch |
| O Jardim da Jujé | Vegan bakery/café | € | Breakfast / coffee |

I'd not make every meal at vegan restaurants; Lisbon has plenty of vegetarian-friendly normal restaurants.

## Rough mid-range budget for two (excluding flights and accommodation)

Food €70–110/day; local transport ~€10–20/day; Sintra trains roughly €5–6 return for two; Pena €40 for two; Regaleira additional; Castelo €30 for two; other museums ~€20–50. Roughly €500–700 for two for the four days.

Tips: don't buy a Lisboa Card automatically; book Pena first; wear proper shoes; go to Sintra early; stay in Baixa/Chiado or Príncipe Real.
