You know, for the longest time, I too, thought the Airspace over NPS areas was NFZ due to 2000 foot restriction. I was informed of the misguided info by SAR104, who was kind enough to point out the 2000 foot altitude is only a recommendation, NOT a specific. I take him at his word, he is quite knowledgable. And, I may also point out that on Sectional Maps, there are no airspace restrictions over the NPS sites. Many NPS sites sit adjacent to private lands, so always give a courtesy visit before trespassing. Here in Colorado, the only NPS park I can think of, off hand, that may be within VLOS for flying is the Great Sand Dunes NP.
Thanks for pointing that out previously SAR104.
Have you ever had opportunity to do White Sands NP from the road. Only drove past! My daughter was stationed at WSMR for almost 3 years. God, what a desolate place! And the NP was closed when we went to visit.
