Bringing 70, 150 or 300 people together is a different job from a cosy team offsite. You need enough rooms under one roof, a main meeting room that actually fits everyone, breakout rooms that energise strategy sessions, and a kitchen that can feed a crowd well, up to three times a day.
The good news? Portugal does large groups brilliantly. Mild weather for most of the year, short, direct flights from most of Europe and venues ranging from sleek city hotels to pine-forest resorts and restored convents.
Below are our picks for corporate retreat venues in Portugal for large groups of 70 people and more.

13 restaurants, bars and beach clubs
Sublime Comporta sits on a 68-hectare estate of pine and cork oak trees and sand dunes, about an hour south of Lisbon. Rooms, suites and private villas are spread across the grounds, so even a big group never feels crowded. This is a top-tier choice for company retreat in Portugal where the budget is generous and the brief is “make it memorable”.
Space to spread out:
Two wings operate as one resort, with villas of two to four bedrooms that work well for team leads or mixed groups.
Proper meeting set-up:
The main events centre has 460 m² that splits into four 90 m² rooms or opens up into one large space, with natural light and full AV. There’s also an outdoor amphitheatre for keynotes under the pines.
Food is a highlight:
With 13 places to eat and drink, from the beach club to private chef dinners in the villas, you can vary every evening without leaving the estate.
Downtime done well:
Spa, tennis and padel courts, a gym and Comporta’s wild beaches on the doorstep.

Serious meeting space:
2,229 m² across 14 rooms, all with natural light. The Morus room alone seats 1,000 theatre-style or 570 for a banquet.
Tech you don’t have to bring:
High-density Wi-Fi with dedicated event bandwidth, a 4K LED wall and 86″ interactive screens in several rooms.
Easy arrivals:
Around 15 minutes from the airport, so late flights and early departures are painless for a large group.
Lisbon on the doorstep:
Rooftop infinity pool and spa on site, and the whole city for dinners and activities after work sessions.
History you can feel:
A 15th-century convent, once a guesthouse for monks, now a five-star hotel with a Cisterna Wine Bar.

92 rooms keep a large team together, with over 1,000 m² of meeting space across 7 rooms for full group sessions and breakouts.
Wellness built in:
Spa with indoor 17-metre pool, hammam and jacuzzi, plus an outdoor pool.
Alentejo on the menu:

Penha Longa Resort sits inside the Sintra-Cascais Natural Park, surrounded by forested hills, a historic monastery and its own championship golf course. It’s a full-service resort with plenty of meeting space, which makes it a dependable choice for groups of 100 to 300 who want greenery and fresh air without a long transfer.
Room for everything:
24 meeting rooms, including a 1,000 m² exhibition space
Close to Lisbon, but feels far away:
Just 35 minutes from the airport, with Sintra greenery and the Cascais coastline both a short drive away.
Built-in activities:
Golf, tennis, indoor and outdoor pools, a spa and walking trails across the estate.
Easy evenings:
Multiple restaurants on site make it simple to feed a large group without coach transfers every night.
The right choice comes down to your group’s size, budget and the feeling you want people to leave with. Every one of these corporate retreat venues in Portugal for large groups can host 70 people or more, but they deliver very different experiences: city efficiency, coastal luxury, Alentejo history or resort comfort.
