Itinerary
Day 1
A relaxed family day: easy breakfast near the marina, check-in at Bolhas Tours, a 3-hour guided boat tour (dolphin watching + Arrábida coastal swim/snorkel), followed by a casual lunch in Sesimbra.
Breakfast by the Marina — easy family start
Light, relaxed breakfast near the marina so kids can stretch and parents can prepare sun protection and snacks. Choose a table with shade and easy stroller access.
Tips from local experts:
- Pick a table near the harbor walkway — easy to park a stroller and keep an eye on kids.
- Buy bottled water and sun hats here if you forgot them; June sun can be strong mid-morning.
- Order simple items (sandwiches, pastries) so you can finish with time to walk to Bolhas Tours for check-in.
Check in at Bolhas Tours Marine Centre
Arrive at the Bolhas Tours Marine Centre for reception, payments if needed, restroom & shower access, and a short briefing before boarding. Staff will handle lifejackets and any child-size flotation devices.
Tips from local experts:
- The marine centre has toilets and showers — ideal for families to change into swimwear; ask staff for the family restroom if needed.
- Bring a lightweight stroller or carrier — the centre and nearby quay are flat but there can be small cobbled sections.
- Confirm child lifejacket sizes on arrival and let staff know about any allergies or special needs.
Boarding at Porto de Abrigo de Sesimbra — safety briefing
Short walk from the marine centre to the sheltered harbour (Porto de Abrigo). Crew will run a safety briefing and help families board the RIB or family boat.
Tips from local experts:
- Boarding is done from the harbour; wear non-slip shoes and hold children’s hands — staff will assist with stepping onto the boat.
- Ask for seats inboard (lower, sheltered areas) if you have toddlers or family members prone to seasickness.
- Keep a small bag with snacks, sunscreen, and motion-sickness remedies easily accessible during boarding.
Dolphin & Whale Watching (guided by a marine biologist)
Cruise offshore along the Arrábida coast. The onboard biologist and crew search for cetaceans and explain behavior and conservation in family-friendly language — expect photo opportunities and interactive learning for older children.
Tips from local experts:
- Children 1+ are welcome; bring a small travel blanket for toddlers to sit on and a sun hat for everyone.
- Use the boat’s shaded area for younger kids during long observation periods and rotate children to the bow for better viewing moments.
- Point out seabirds and explain simple cetacean behaviors — the biologist often highlights easy-to-understand signs that excite kids.
Visit & Snorkel in a sheltered Arrábida bay
Anchor in a calm bay along Parque Natural da Arrábida for a swim and snorkeling session. Snorkel gear and bottled water are provided; crew will supervise entry and exits for safety.
Tips from local experts:
- Bring lightweight reef-safe sunscreen and a rash vest for kids — water can be cool in early summer mornings but warm enough for a comfortable swim.
- Ask the crew for swim steps and a hand when entering/exiting the water with small children; lifejackets are available for non-swimmers.
- Keep snorkel sessions short and supervised — alternate kids between snorkeling and resting under the boat’s shade.
Return to Sesimbra & check-out at the Marine Centre
Disembark at Porto de Abrigo and return to Bolhas Tours Marine Centre for showers, changing, and final check-out. A good moment to download photos and thank the crew.
Tips from local experts:
- Allow a quick shower/change for children before heading to lunch; towels are available at the centre if you need them.
- If anyone feels queasy after the trip, sit in the shaded marina area for 10–15 minutes and give water and light snacks.
- Ask staff about souvenirs or any photos they may offer — often they can send digital copies suitable for family albums.
Casual family lunch in Sesimbra — fresh, kid-friendly seafood options
Enjoy a relaxed lunch near the marina with simple fish, grilled options, and side dishes — choose a restaurant with high chairs and a kids’ menu or flexible portions.
Tips from local experts:
- Ask for half portions or a plain grilled fish/ chicken for picky eaters — many local restaurants are happy to adapt for children.
- Request a table near the entrance for easy stroller access and quick exits if kids need a short break.
- Try local dessert options (fruit or custard) for a light finish; avoid heavy fried items after a sunny morning on the water.
