I have made a reservation for a 3 day stay in the park for August. I am wondering if there are any park veterans that can help me with some information. I use a wheeled walker to get around. I will be travelling solo and I am wondering if there is any info on disabled access in the park? I like to walk but my body does not and it can make it difficult when travelling to national parks. They are really designed for active mobile people who can walk unaided. I expect that much of what I do will be driving around and sitting admiring the views but I would like to try some gentle walking. Any information would be appreciated.
