First we visited the legendary Burwalls Cave. This cave is quite a scramble to get to, but it's worth it. When we went, the ramsons (also called wild garlic) were covering the woodland floor, giving the mild garlicky smell that always means 'summer is coming' to me.
The cave itself is just under where Burwalls House now sits at one end of the Clifton Suspension Bridge. Before the mansion and the bridge were built, there was an Iron Age hill fort there.
Although some of the cave looks natural, I'm sure that other parts were dug out, built up and remodelled to make the place more like a grotto when such things were fashionable. The Bristol area has a couple of other notable grottoes, including ones at Goldney House and Warmley.
Unfortunately, the cave was a mess when we arrived, with old sleeping bags and rubbish all over the place. There were no signs of any current occupants either.
It looked a lot better afterwards, and in one dark corner we were rewarded by coming across a roosting bat. We also let the rangers, who look after the cave, know what was there. Hopefully it will be in a more welcoming state now.
