Stirling Castle was another one of my day trips from Edinburgh. It was an easy train ride from Waverly Station lasting around 50 minutes and then a 15-20 minute walk from the station to the castle. Do note that the walk is mostly uphill, it’s not particularly challenging but if you have mobility issues you can catch a bus up to the castle. I had pre-booked my ticket which are timed entrance (as a member of English Heritage my ticket was free); generally an adult ticket is £17.50 online, £19.50 if bought when you arrive.
