Just a quick tip, if you're going to take the boat trip along the Pictured rocks go early but book the last tour of the day. The setting sun brings out the color of the rocks that you won't see during the other tours.
This is a fantastic garden to visit. Plan on about an hour to an hour and a half to walk through and enjoy everything. This is one of the best laid out and meticulously clean gardens we have been to, every plant is placed with a great deal of thought as to how it will fit in with the area. There are also numerous sculptures in the garden many of them hidden in laces you would not expect. If you love gardens and are near this one don't miss it.
We've been fulltiming in your motorhome since 2001 and this is one of the nicest parks we have ever stayed in. When we're in this area this is the park we will stay at, give it a try.
A very nice tour but extremely loud, they supply you with ear muffs to wear during certain parts of the tour. They take you from start to finish showing you every detail of building a Airstream. After seeing how they are built and the testing they go through you'll understand why they last forever. Get there a little early because the number in the tours are limited.
