How far in advance should reservations be made? And is the park usually full?

There were still spots available when i went. It is undergoing some great renovations book now for summertime fun!

The yurts are amlost always booked up about 6 months in advance. Dont expect to find anything open on a holiday weekend. We usually reserve our site for August in March.

For the summer months, as soon as you know you want to stay. If you want a yurt, good luck! Those are rarely available. In the off season sites are usually always available.

I would make reservations a month in avance if its near summer. Its a big park so vacancies arent hard to come by

Before summer, pretty crowded during the summer
