Dauphin

The Dauphin near Thame is one of those English landmarks you could easily miss if you weren't looking for it - which is precisely what makes it worth seeking out. This striking stone structure commands attention from the surrounding Oxfordshire countryside, and once you're there, the views across the rolling landscape are genuinely impressive.

It's the kind of place that works well for walkers tackling longer routes through the area, though be warned: there's not masses to do once you've arrived and had a look around. Ten minutes to examine it properly, maybe another twenty if you want to linger and appreciate the vistas. History enthusiasts will find it worth the detour, particularly those interested in local landmarks and the stories that shaped the region.

The nearest base would be Thame itself, though if you're staying at one of the local holiday parks - Lashlake Barn and Common Leys Farm both rate five stars - Dauphin makes for a solid half-day excursion. It's genuinely worth combining with other walks in the area rather than making it a destination on its own. The surrounding countryside is what sells this one as much as the landmark itself.

I'd recommend visiting when the weather's clear. You'll want decent light to make the most of the views, and muddy ground can be a right pain after rain. Late morning or early afternoon gives you the best shadows for photography if you're that way inclined.
