We discovered this event while visiting Sequoia National Park about three years ago. We like music, but were not necessarily jazz fans. However, we enjoyed this so much we attended again this past April and will go again in the future. I think the official title is JazzAffair and is presented yearly in early April. Their web site will provide complete details. You can spend part of the day visiting the park and enjoy wonderful jazz during the afternoon and evening. The Kaweah RV Park in Three Rivers, which is right at the south entrance to Sequoia, is our favorite.
