Steep walk up to McCaigs Tower but well worth it when you reach the top. The views are spectacular.
If you aren't feeling as energetic or have any difficulty walking you can drive to the base of the tower. There is a small car park that's also free.
Entry to the tower is free and there are no time restrictions on how long you can stay. There is a small garden at the top within the tower and a couple of benches.
There are also a couple of benches on the viewing platform where you can sit and take in the views.
