We went to Holyrood Park on a bus.
We walked into the park and we met the ranger, he was called Gordon and then we walked up the hills in the rain!
We learnt that a part of Arthur’s Seat used to be a beach and there was a bit that was slanted which lava went down, but that was a long time ago.
The volcano last erupted hundreds of millions of years ago.
It used to be covered by a glacier which was much higher than Scotland’s biggest mountain.
When the volcano explodes, the lava can turn into rock, and we got to have a look at some lava rocks.
