We stopped in one day while it was raining and was pleasantly surprised to really enjoy the visit. They ask for a donation when you walk in but don't insist on it. The person at the desk was very helpful with information about Mt. Washington, whether it was about the weather or what you need to hike it. There are plenty of exhibits explaining all about the changing weather along of course, with the prerequisite gift shop. The items they carried were unusual, science oriented and would make great gifts if you are tired of kids playing with ipads, etc. Great place to explore and enjoy.
