Pump House Indoor Water Park at Jay Peak!
Jay Peak is a ski resort about an hour north of Stowe (we get to Stowe in 4-5 hours depending on how many potty breaks we take!). I'm not much of a skiier so I can't say much about the actual mountain and resort but it's well worth the drive for the water park! My brother did a little research and found some coupons that allowed 6 of us to get in for just under $100! Since we were there 'off-season' it was pretty quiet and the lines and crowds were small.
This is definitely a family-destination that is worth the trip. The kids area is great for little ones and there's enough excitement for older kids and adults. I went for the restful version and enjoyed watching my kids have fun while sipping a cocktail!
