This was my second time on this tour and I was just as pleased as the first time. We selected the tram tour since a member of my party had mobility issues. Both times the tour guide has been gracious, well versed, and entertaining. The interaction between the guide and visitors keeps the tour interesting and time flies by quickly. You don't need to be an avid gardner to find this useful - the gardens are an incredible site to behold and the sculpture is really great. We enjoyed the gift shop, the plans for growth and the contribution the garden is making to sustainable industry. It's a great value for both time and money. Check it out!
