Hola Teresa, no es difícil, no tiene escalones, se baja en espiral lentamente. Lo único que podría tener dificultad, es que, entre más se baja, el piso es más húmedo, y podría ser resbaloso. Pero eso, con unos buenos zapatos (que no sean planos) y algún soporte, está genial. No pierda la oportunidad de ir y descubrir este lugar tan hermoso! Saludos

You don't have to climb back up as the tunnels bring you back out at one of the lower follies (depending on which route you take). You do have to go up the hill to get to the top entrance which is fairly steep up the many paths in the park. Climb down through the well is a stone spiral staircase - but no more difficult than a normal stairs although slightly uneven.

Getting around Sintra can be a little tricky for a tourist. There is a train you could take but, once you get to the station, it might get a little hard to get around. The walks to the Quinta and Sintra itself are for the brave ones only as the walks can get a bit intense. Driving, it's recommended for the locals who know their way around the winding, steep, narrow roads. We booked our visit with a tour company in Lisbon instead (since moving around seemed a bit challenging, didn't want to spend the day getting lost :) . The day tour was great and we got to visit Sintra without feeling rushed, we are glad we did.

Io ho preso una vettura con autista che mi ha portato da Lisbona a Sintra. Il modo più economico è col trenino che parte da Rossio. Impiega circa 50 minuti.

Hi - I did not arrive by train so I can't give specific directions. I think the walk would be 20 to 30 minutes perhaps. I would use the Google map app - either live or through the downloaded offline maps to help with this.

Think that there are toilets near exit. Go when it’s not to hot. A lot of people, bu the park is big.

It surely depends on the season. We were there in the morning & it wasn’t crowded, at noon there were quite a lot of people. The positive thing is that the whole place is so big that it does not actually matter whether there are crowds or not.
