The BLM Kanab Visitor Center is a very nice building. And it's also the building that houses the infamous Wave lottery drawings every day. We showed up once and were not one of the lucky few to be chosen (10 people get selected to be precise). There was a lady who has showed up 21 times and still not been chosen for the Wave yet, so not to be the bearer of bad news but definitely have a back-up plan in place in case you don't get chosen. There are pool plenty of attractions nearby. I would recommend the BLM Kanab Visitor Center to all, just make sure to have a back-up plan for your days.
Their main activity is to arrange the daily hiking pass lottery for the Wave, where 10 hikers are permitted each day. They do also provide information on other trails and there is a small exhibition there about the geological parts of the park. I was quite disappointed by my visit there as the rangers didn't really help much and did show any kind of enthusiasm. They didn't appear to like their job. Very unlike what I have experienced in other national and state parks where the rangers are all fired up.
This visitor center was exactly what you want a visitor center to be, friendly and informative. I wish this one were also a little luckier for me as I did not win the lottery for the Wave hike. Aside from that, my visit here was great. I talked with 2 workers, both had great recommendations for the area. I also like collecting stickers of places I have been and I was pleased that they both had stickers and that they weren't just the same boring GSE letters (although they did have those :) ). The facilities were also very well kept.
The woman at the desk was very knowledgeable. She helped me with the map to the places I wanted to see. Let me know of weather and road conditions. Although there was a *little* (and by little, I mean a lot) more water than expected in Buckskin Gulch, I can't fault her for that. She also had great suggestions of other places to take my kids hiking.
I called the visitor center ahead of a trip and RUSSELL was super condescending and laughed when I asked questions about the area I was visiting. I'm not familiar with the area so getting information is what my taxes pay these government schleps for. UPDATE: When I picked up my permit to do Buckskin, RUSSELL was again very unpleasant to deal with. He answered my questions but tried to make me feel stupid for not having a 4x4 truck to go drive areas when he discouraged my partner and I from doing Buckskin. My partner felt like he was looking her up and down basically saying, "you can't do that hike." Another employee in the visitor center scoffed when I asked for a detailed map of the canyon. Instead of just providing accurate and factual information these two clowns just discouraged us from doing the canyon we had a permit for and had prepared for months to do. I would have expected them to just us the conditions and perhaps discuss accurate preparation for the canyon. Instead, I got the accurate conditions of the canyon from other locals. Oh, and look, RUSSELL, this hot blonde girl did that slot in some seriously tough conditions!
