We recently stayed at Pine Trees, and our stay was extremely peaceful, we were there for five nights (mid August) and were the only unit on the site the whole of our stay. We had the choice of pitch but really struggled to level our motorhome and had to move twice, eventually settling for 'good enough' (glad we did not need to have our fridge on the gas). The cost of the stay included electricity which we considered reasonable, and the Toilet and shower block was very clean and tidy, although we never did manage to get hot water out of the shower, but didn't mind as we were on electric hook-up so we were able to use the one in our van. the A16 is a fairly busy road and you have to be sharp-eyed to catch the sign for Pine Trees, especially if you are coming up the hill, as it looks as though you are pulling onto someone's driveway from the road. The owner is very welcoming and did say that if we struggled to get off site if it rained he had the equipment to pull us up the hill. It was cash only so we had to make a little trip out to get enough to pay for our stay. We cycled a lot and kept our van on site for most of the stay, this had a lot to do with the levelling issue. However, it was close to, the Aviation centre which was the main reason for our visit. Tattershall castle and Gumby House were also within cycling distance and so was Spilsby the nearest town. Disappointingly for us, there was no pub within walking distance so eating out wasn't easy, and something that we like to do. We were able to cycle to one about three miles away but obviously, this impacted in us enjoying a beer with our meal. The view from our van however was spectacular, we could look over to Boston and could see the Stump in the distance. There were rabbits running around in the field opposite in the evening which was cute to watch. The site is overlooked by a few houses but not intrusively so. My only advice to anyone wanting to stay here is you really need some good, high, levelling gear as it really is quite steep, the pictures i have seen do not make it look as steep as it is. but if you can put up with that then you will enjoy your stay, we did.
