I've stayed at Clumber many times, usually as a one night stopover. It is a few years since I stayed longer, but I stayed three nights recently to enable me to race Outlaw X (70 miles triathlon) at Thoresby Park on 22 September. Arriving early afternoon on a Friday is a very busy time to arrive. But the wardens were welcoming, friendly and efficient. The site itself is lovely in every way. It's a large area and is a credit to the wardens. The atmosphere on site - like most - does vary between when the site is full and when the site is quiet. I prefer the site to be quiet but this comment shouldn't prevent anyone from staying when it's busy. It's still lovely. I run (among other activities) and the site is perfect for running offroad throughout Clumber Park.For a shorter run I recommend the Clumber parkrun held every Saturday morning throughout the year. It is only maybe one mile to jog to the start from the campsite. (Nice warm-up and cool down after the parkrun.) The parkrun is friendly and welcoming (like all are) on a lovely route within Clumber Park. I'll leave others to recommend places to visit. Except to say my event was held at Thoresby Park, which is less than 10 mins drive from the site. Thoresby Hall is an hotel but much of the extensive parkland grounds is open to the public, with refreshments available, and there is plenty of free parking. Including plenty of space for motorhomes.
