Grass Eyot

A small wooded island on the Thames just outside Maidenhead, Grass Eyot is the kind of place you stumble upon rather than plan for. The island sits in the river bend between Old Windsor and Maidenhead, accessible by footpath from the riverbank - though you'll need to work out the exact approach on the ground, as it's not a formal visitor attraction with clear signage.

What you get is a proper bit of riverside woodland, quiet and undisturbed, with the Thames moving past on both sides. It's genuinely nice for a wander if you're exploring the towpath, though the island itself isn't enormous - you're looking at twenty minutes to half an hour to have a decent look round rather than a half-day outing.

This works best for walkers doing longer stretches of the Thames Path, or for anyone based at Hurleyford Farm or Hurley Riverside Park who fancies a riverside detour. Kids might enjoy the hunt to find it more than the place itself. The appeal is gentle and low-key - if you're after dramatic views or proper trails, you'll be disappointed.

Timing-wise, go when the towpath is dry and the light is decent, which usually means late spring through early autumn. Winter's bit grim underfoot. There's no facilities on the island itself, so come prepared. It costs nothing, and that's about right for what it is - a pleasant surprise rather than a destination in itself.
