I can not stress enough the incredible feeling of being here. They have done such an amazing job in the creation of this place. There are articles of clothing from artists who performed, set lists, and even notes that attendees were leaving so their friends could find them. There are interactive things to do while walking through and incredibly well-done videos. The entrance fee is $20, but it's so well worth it! The staff are kind and helpful, and prices for items in the gift shop are a tad high; however, that being said, they are still lower than in the actual town of Woodstock. There are 2 areas to peruse on your journey the upstairs is the main museum with most of the items, and the downstairs has a few really cool things as well including a piece of the actual stage and stacks. So freaking amazing! I'd love to go back, but at a minimum... this is checked off of my bucket list.
There is also a food court type of area on the main level with very reasonably priced food, drinks, coffee, etc. There also vegan options available and they make the food there. So that's a bonus. Highly recommend the road trip. You won't regret it!
