Gibraltar Cable Car

We just did that in September. No need for a tour. In fact, I would avoid the taxi tours like the plague.

Walking down was great. Our route was Top Station > Skywalk > St Michael's Cave > Queens Balcony > Apes Den > Old Queen's Road > Union Jack Steps > Town. We didn't do the Windsor Suspension Bridge but it close to that route, so you could add that. Views were great. Explanatory signs were at all the sights. Apes were at the Apes Den, but there were many more at Top Station.

Advice: make sure you get your ticket for the cable car in advance. We had a reservation and still waited about an hour to get up. Without a reservation you would have TWO lines that long. Get the One Way Fare (https://naturereserve.gi/tickets/).

Word of warning: The walk is moderately steep. My wife ended up with a sore knee. Take it slow, enjoy the views.

I used to live near Gib and always took visitors up the Rock.
Getting the cable car up and walking down is fun, but hard on the knees.
We would sometimes come down halfway on the cable car, as the best place to see the macaques is their feeding ground at the halfway point.
I found that with a good driver, the taxi tours were great as you learn so much. At St Michael's Cave, they drop you off and meet you at the other end after you have walked through.
The macaques have learned how to unzip back packs!

Don’t know if this still happens but some years ago my wife and I were walking towards the bottom station past hawkers trying to sell taxi or minibus trips to the top. We said we were getting the cable car and they said it wasn’t working today so would we leave to take their tou. Of course, the cable car was working.
