You will have to travel with a guide that is provided by the lodge, as part of the package. If you are with a photo workshop you will be with 5,6 or 8 others depending on the group size. If you go as we did (a couple) you will be considered a "single" and will have a guide all to yourself .... much better in my opinion.
We live 20 minutes from the Great Smoky Mountain National Park .... annual # of visitors = 9 million Lake Clark NP # of annual visitors = 9,000
The only way to get there is by small plane or boat
