I think it was less than 20 pounds. There is also a convenient bus service. We were going from the Holiday Inn (near the frontier) to the Med.

I strongly suggest purchasing your tickets (and print them out) online. The line to purchase tickets was quite long and since we had bought them in advance, the staff ushered us around the crowd.

Hi, St. Michael's cave is closest to the cable car, so usually people see it first. We didn't go to the WW2 caves because they were closed.

We were going to buy the return cable car ticket, until we saw the queue. It was 3pm and the line was still going to take an hour before ride. I don't know if you can bypass the queue, if you have pre bought your ticket. At the top, the nature reserve is over a wide area with the cable car in the center, and I think you can walk around with out a specific ticket. The way we did it was to share a taxi for the same cost of the return cable car and we had a proper tour and entry into the caves and the castle as well as excellent advice and photos of the apes. We went early May if you want to read my review. I know this is long and doesn't exactly answer your question but I hope it helps and you have a good time.

While we were there they were starting about 9am and finishing about 8 pm. When a cruise ship was in they started earlier.

Cost is about £10 and you can pay with either uk Stirling or euros. Check the exchange rate before travelling as you may get more Stirling than euros and you can pay with either throughout Gibraltar

Sorry only just seen this. May be a tad too late for you now! Saw families using strollers but it is steep.

Hi, we just saw monkeys there because we did not perform the full visit.
