We take the ranger guided hikes whenever we visit Yellowstone and Tetons. Nine year old grandson really enjoys them. The narrated boat tour across Jackson Lake is great. Our guide told us about a plane crash that occurred on top of one of the mountains, showed us an Osprey nest, explained their hunting habits and abilities, etc., all things children as well as adults would find interesting. We attended an exhibition of raptors and their habits at Jackson Lake Lodge. We also attended a talk about Grizzlies, also at Jackson Lake Lodge. Our grandson listened with rapt attention to both presentations. There are so many things to do for all ages, the Junior Ranger program is excellent for younger school age children. There are dinner picnics where you ride the boat over to an island and many other evening activities. Many of the campgrounds offer evening talks at their amphitheaters and every one we have attended has been quite worthwhile. Best wishes for a fun and interesting trip for all.
