Spend the morning on an accessible, sandy beach with calm water and beach amenities; ideal for sun, easy swimming and shade umbrellas; beaches are public and open all day.
Enjoy a relaxed seafood lunch at a harbourside restaurant in Sesimbra (choose a place specialising in grilled fish or arroz de marisco); restaurants typically serve lunch from 12:00–15:00. Book a table for a sea view and easy seating.
Short, gentle walk to the Fortaleza/Castle viewpoint and along the promenade for sea views — light walking and benches make this elderly‑friendly; small castle area is usually open late morning–early evening (check seasonal times).
Choose a highly rated seaside restaurant (book ahead) for grilled fish or seafood rice and a calm atmosphere — many places open for dinner from 19:00–23:00 in summer.
Visit Setúbal's famous market to see outstanding fish, local produce and colourful stalls; market hours are typically early morning to early afternoon (often ~07:00–14:00) — best to go before midday.
Take a short boat trip from Setúbal harbour to see resident bottlenose dolphins and the estuary — trips usually run between ~10:00–18:00 in summer and last 1.5–3 hours; choose an operator with shaded seating and calm‑water options.
Enjoy a leisurely lunch at a Setúbal waterfront restaurant (try fresh grilled fish or local sea bass); many venues are comfortable and wheelchair‑friendly — book a table with harbour views.
Short 20–30 minute drive to Azeitão for local specialities: sample Azeitão cheese (queijo) and visit a family winery or cellars such as José Maria da Fonseca for a guided tasting — many tastings run 11:00–18:00 but reserve in advance.
Choose a relaxed, well‑rated restaurant back in Setúbal or a traditional tavern in Azeitão for regional dishes; book for a quieter table suitable for your mother.
Drive ~20–30 minutes to Setúbal harbour and take the short ferry (or car ferry) to Tróia; ferries run frequently in summer but check the timetable and vehicle slots in advance.
Explore the long, sandy Tróia beaches and see the exposed Roman fish‑salting factory remains; very low‑impact walking and benches available — open all day.
Eat at a resort or harbour restaurant in Tróia (fresh, light dishes) or return to Setúbal to shorten driving; lunchtime is busy so reserve where possible.
Short drive through flat rice fields to the chic but low‑key village of Comporta; a peaceful place to wander the narrow streets and shop local boutiques.
Late afternoon at Praia da Comporta with wide sandy shore and shallow water; excellent for a relaxing swim and to avoid the midday heat — beach is public and open all day.
Dine at the well‑known SAL (or another reputable Comporta restaurant) for a stylish yet unfussy meal focusing on local produce; reserve in advance as places are busy in August.
Drive inland (approx 1h30) to Évora to avoid the heat and crowds; roads are straightforward and parking near the historic centre is available but can be busy in summer.
Start with a gentle walk around the Roman Temple and the charming, compact UNESCO‑listed old town — the area is mostly flat and easy to navigate with benches for rests.
Visit the cathedral (usually open ~9:00–18:00) to see Gothic architecture and views from the terraces; the interior is accessible but the terrace climb can be steep — skip the climb if preferable.
Reserved lunch at Restaurante Fialho (classic Alentejo specialities) for a genuine regional meal in Évora; Fialho is a local favourite so reserve a table and ask for a quieter seating area for your mother.
A short, moving visit to the Chapel of Bones near the cathedral; usually open around 9:00–19:00 and only a brief visit is needed (the chapel is small and can be cool inside).
Enjoy a slow coffee or iced tea in Largo do Conde de Vila Flor or a shady café before the drive back to the coast; return journey in comfortable time to avoid late evening traffic.
After a full day, opt for a nearby, calm dinner — choose an easy menu (salads, grilled fish) and a restaurant with comfortable seating to suit your mother.

Visit a nearby quinta or wine cellars for a gentle tasting and short tour (many openings 10:00–18:00) — tastings are seated and can be tailored for small groups and limited walking.
Return to Setúbal or stay in Palmela for a leisurely lunch; choose a restaurant with shade and easy access — seafood or Alentejo dishes are good local options.
Take a late‑afternoon stroll in Albarquel park (Setúbal) or a short visit to an Arrábida beach with easy access (Galapinhos can be busy, choose a nearby calmer cove) for another gentle sea experience.
Finish the day with a recommended Setúbal restaurant known for seafood and a calm ambience; book a table early and request easy access seating for your mum.
Short drive across the Ponte 25 de Abril (or around via A2) to Almada and Costa da Caparica for one last beach morning or scenic view of Lisbon across the river.
Caparica offers long sands with facilities and cafés; alternatively visit Cacilhas waterfront for a gentle riverside stroll and great views of Lisbon (ferry and cafés open from early morning).
For a memorable last meal choose Ponto Final (if you take the quick ferry to the south bank) with lovely views or a comfortable beachfront restaurant in Caparica — both offer fresh dishes and relaxing sights; check opening times and reserve.
