We stayed here for 4 nights in June 2023. The CL has both grass and hard-standing pitches (which are huge) and is in a beautiful, quiet rural location. There is also an adjacent private small site by the same owners who don't mind whether you choose to set up on the CL or the private part (subject to space, of course). Toilet and shower facilities were good and clean For Cyclists, the site has immediate access to Sustrans Route 1 with easy almost totally flat ride to Lincoln (5 miles), Woodhall Spa (12.5 miles) and beyond to Boston. The owners made us very welcome on arrival; they can suggest places to visit during your stay. The local bus service to Lincoln stops within 50 metres of the site entrance and Historic Lincoln (Cathedral and Castle) are worth a visit. Louth (some 30 mins drive away) is also worth a visit (ask about market days). We also visited Gainsborough Old Hall (again, some 30 mins drive) is English Heritage and which was very interesting but Gainsborough doesn't offer very much else. It was our first trip to this part of the country but would not have any reservations about recommending Diamond House CL as a suitable place for a relaxing stay.
