This (still) easy to find site, lies directly besides a field track around 100m from the road right after the first gate. It is signed from the R353, but I didn't see any hint at the field track itself, that lies around 1km south of the R353.
It seems, that the tomb once had three capstones, with the middle one now collapsed. The tomb is heavily overgrown, which is a shame. Cleared form all these bushes and trees, these tomb would be very impressive.
