For first time travelers to the US and Canada, this tour is an amazing option to get a grasp of the culture and attractions the two countries have to offer. Larry (tour guide) was excellent! He really knows about his stuff and is always willing to accommodate any of your concerns. He's also willing to answer any questions you have regarding anything (and I mean anything, regardless of whether your question involves the tour or not). However, I would not recommend this tour to those which struggle to walk moderate distances and those who find stairs difficult as this tour heavily involves these activities. Also, it is also important to keep in mind that walking in the pouring rain is inevitable so better to come prepared and bring a waterproof jacket, a cap, an umbrella and shoes which can get wet. With regards to meals, there isn't really a lot of options for breakfast and their meals severely lack vegetables, but they do offer fruits. Food servings in America is excessive as compared to those in Asian countries so it would be best to just share food if you don't have a big appetite, so as to not be wasteful. I also recommend bringing your own refillable water bottle because most of the places have water refilling stations if you keep your eye out for them. Refilling water in hotels during breakfast is also an option.
I travelled with my 23 yr old daughter and we had a great time. Lots of superlatives which have been covered by reviewers below, so I will not repeat them, but suffice to say that this trip exceeded both our expectations in terms of the amazing variation in landscape in the iconic National Parks visited, and the diversity of activities - ranging from exciting hikes, to laying on the ground in Death Valley looking at the Night Sky. Never a dull moment - and our guide inserted little surprises at regular intervals.
A well organised trip visiting 3 Islanda. Very educational. Our leader Tom had excellent knowledge. Volcanoes, snorkelling, great accommodation. Could have done with more free time and beach work however.
