At the Peak
Tram station, you can get a one-way or round-trip
ticket (I think the return journey of a round trip ticket
is only good for the same day). There usually is a line
for the Peak Tram, but it moves fairly fast. Once you
are on the tram, ride it all the way to the end.
If you don't want the excitment of riding a cable tram,
there are buses that go up to the peak, but they take
longer and are not as interesting a ride.
