Beech Hill Campground in Twin Mountain NH is a great Campground if you are looking for a quiet and relaxed camping experience.
There are not a lot of frills here but they do have an indoor pool and a small playground.
Their camp store is stocked with the camping basics and not overly priced.
The sites are well-spaced apart and have lots of trees. The roads are tight with only enough room for one vehicle at a time so it's best if everyone moved using one-way traffic rules, however, not everyone does.
The prices are very reasonable and close to many great hiking trails. We had a relaxing time and enjoyed the mountain scenery, even if it was raining during part of the weekend.
We will be back there again.
