Im trying to find out if assisted stargazing is available every night in Bryce - ie with an expert (Dark ranger). We shall only be there 1 night having driven from Las Vegas on morning of 19 Sept and then moving onto Zion for 2 nights on 20 Sept. All I can seem to find on the parks official sight is info about an astronomy festival which took place in June. As this is one of the highlights of our trip (from UK so not coming back again for a while) I'd really like to do it properly with someone who knows a thing or two. Similarly ive heard that viewing at sunrise is also recommended. Any advice on best way to do this please?? We need to cram in as much as we can into our short time there.
