The old town is right by the bus stop listed. It is right by the McDonalds and Burger King. On the other side of the acqueducts, there is the old town. You walk right under them. Tourist information and roilets are also right there.
The whole area is pretty walkable. If you have problems with walking on hills, it might be a bit of a challenge.
I haven't taken the bus as I prefer the train. Others who have had really liked it. I might suggest a motion sickness pill if you're prone to motion sickness as you cross the mountains.
Thank you for your information
Let me start from the beginning. The bus to Segovia will end in the bus station of Segovia. There are two stops along the way: one at the northern end of town, and the second and final one is in the bus terminal. The SECOND stop is what you want; this is the stop inside of the bus terminal. This leaves you right next to the major sites, whereas the first stop is farther away
The bus station is situated right in the heart of the old town, so you will not need to look for any form of public transportation. In fact, you can see the aqueduct from the bus station, dead serious. All you do is follow one road for two minutes, and you're literally standing in front of the aqueduct. It's nearly impossible to get lost or have troubles finding it.
And with response to the other reply, I would respectfully disagree and not take the train (unless you really do not like public busses)
I say this for a few reasons: First, the bus only takes about a half hour longer than the train, but the train does not drop you off near the old town, so any time saved taking the train will be spent getting to the heart of the city from the train station (whereas the bus drops you off directly there).
And second, the train costs a lot more than the bus.
Again, if you really would prefer a train then i won't argue. But if you dont mind busses, i find it a far better option
It is a public bus service. If you leave from Madrid Moncloa station, you will be on a bus from the company named La Sepulvedana (as in the title). From Moncloa they are basically the only station that goes to Segovia, so chances are you're on that bus. But it's not like a private company with its own bus terminal and whatnot. I hope that makes sense.
They are coach busses. Seats are far comfier than school busses.
Thank you, Joo chan K. I have to wait before tickets are available on the dates we plan to travel in September, but the website you provided is very helpful. Thanks, again!
