We all know that Blenheim Palace is beautiful; both the Palace and its grounds. Amongst it all you can walk as much or as little as you want. In the Palace, unlike the grounds, there are numerous places for a refreshment break. The immediate manicured gardens are very attractive. However, the 2,100 acres of Capability Brown landscaping is what we find the most stunning. Much of visiting Blenheim comes at a cost; only to be expected of one of the country’s leading tourist attractions…there’s a lot of hoovering to be done in the Palace! There are though, a number of public footpaths that cross the estate that can be accessed via a number of private gates. Check them out, here’s one link; https://www.freeblenheim.com/.
If local enough to frequent a few times a year then their annual pass is good value. https://www.blenheimpalace.com/
