We stayed for 3 nights in May this year, on route to a wedding in Scotland. The site is very nice and split into 2 areas, the upper part appearing to be an extension and contains the serviced pitches. There are also some static caravans in this upper area. From here you can walk into the forestry area.
Things to do - we did the obligatory boat trip on Ullswater.
Here is an extract from the CC website: "A lake cruise on Ullswater is a must, with the option of a scenic walk between Howtown and Glenridding (7m). For the energetic, the Rookin House Farm Centre next door offers go-karting, quad bikes, archery and horseriding (to name but a few activities), but it is advisable to book in advance to avoid disappointment"
