Enjoying the top tourist spots in the UK doesn't have to break the bank. In fact, you can experience some of the best places to visit in the UK without spending anything. If you do your research (and take your own picnic) you can have a great day out, even on the tightest of budgets.
1. Arthur’s Seat, Edinburgh
Arthur's Seat, one of Edinburgh's seven hills, is an extinct volcano and site of a well-preserved fort. Getting to the top involves quite a hike, but it's achievable for most fit adults and kids, and the views from the top are more than worth the effort.
