Cascais has always been a favourite haunt of the Spanish royal family. They lived here for a time and this competition, held here annually in March/April, is named after King Juan Carlos.
The event consists of a number of International Dragon Class regattas and is a sporting event of major national and international importance.
Why not pick up a free bike from BICAS - Bicycles of Cascais. They have three booths , one by the train station, One along the coast near Casa da Guia and one in front of the Citadel. The municipality of Cascais offers to rent bicycles for free, as part of an initiative to get people to use bicycles rather than cars.
Cycle to beautiful Guincho Beach. Beginning on Avenida Rei Humberto II de Italia, just outside town past the Marina, is a cycle lane and footpath stretching for five Km to Guincho Beaches. This route runs along the sea and is ideal for morning and evening strolls and to ride a bike. It only takes about fifteen minutes to reach the Boca de Inferno.
To pick up a bike , you'll need a passport or ID card.
Hans and I saw several during our two week stay. Folks zipping around town on their Bicas with the basket & yellow cardboard "Cascais Bicas" in front and there were always some riding along the cycle lane to Guincho.
Along the promenade between Cascais and Estoril, you will find CIRCUITO ACTIVO. The community wanted to promote healthy lifestyles and get people active. An area was set up with sit-up beds, monkey bars, and many other excercise venues. Hansi did some sit-ups and got to the count of ten, before he tuckered out. Maybe our community should have something like that along our jogging trails.
Cascais has a beautiful coastline and people enjoy sailing and boating in that area, sometimes there are competitions there. So what are you waiting for, go there and enjoy the sea and the sun!
Take a look at my photo, you can see how many beautiful boats on the sea.
If you are a sailing or motorboat lover Cascais will not let you down. Enjoy the magnificent coast and amazing hidden spots and views. During weekends you may find some “traffic” mainly on sunny days, when all locals seem to go out with their boats.
The 10km rocky coast between Cascais and Guincho will provide fishing lovers with lots of places for enjoying their sport. Beware that in some places are signs alerting where fishing is allowed. In any case be very careful with the sea, as sometimes there are unpredictable waves and men haven fallen into the rocky dangerous coast. Use sunscreen and hat, as sun is very strong here even during cloudy days.
There is a very nice and well-maintained bike path that runs from Cascais to Gincho (the sand dunes).
On the weekends you will find rollerbladers and walkers using the bike path so be careful.
It is a nice day out along the path and the path offers some awesome views of the cliffs and the beach.
Equipment: Bikes are available all over town for a very very small fee. (FREE)
You may rent a bike in Cascais to ride a bit in this road across the sea. The views are great. You may also do it by foot.
Starting near the Cascais marina there's a track for runners, walkers or bikers that goes for some kms til Guincho. The track is almost flat and always by seaside.
There are lots of places to fishing in the Cascais coast.
I found fishermen in the Boca do Inferno area but it seemed very dangerous because the sea is strong there.
Guincho is consirered the best European beach to windsurf. Sometimes the wind is so strong that it hurts your skin!
