Riverside Farm camping in Rudgwick off the Downs Link. Bit of a weird one it has to be said.
It's a farm that lets out a couple of fields for camping. Two flushing toilets equipped with antibac wipes and hand sanitiser, the shower is closed due to Covid. They were very nice and friendly and delivered our firewood & fire pit to our pitch, however the 'firewood' was mostly bits of skirting board and door frame with nails in, bit of a funny thing to pay for. You can camp close to the river and it was not busy. But it seems to be a full-time permanent home for many in caravans with big awnings, which gives it a different vibe to a more usual site. The kids on site seemed to enjoy the horses, ponies, sheep and chickens.
Knepp Wildland camping in Dial Post. Very expensive but absolutely fantastic, beautiful place with lots of walking and wildlife on the wider site which is huge. Showers and toilets, (also a couple of outdoor baths) and hand sanitiser everywhere. Huge amount of space between the mowed-in pitches; they could pack people in but they haven't. Provided firewood that still looked like logs as above, and complimentary old newspaper to burn. A very useful shop onsite that sold local beer (only 1 household at a time allowed inside). They eagerly pointed us towards their cycle parking which was a small row of wheelbender racks. I politely explained why we would not be using them. I think they are pretty booked up for the near future but we'll definitely return.
