We are planning a 9-day vacation in June that will begin and end in Denver (we'd love to go longer, but that's all the time we have). We have two kids (7 and 9) and are considering visiting Arches, Canyonlands, Mesa Verde, and/or Rocky Mountain. In the parks, we're up for some short, easy hikes. If anyone has information regarding ranger-led tours or really good private tours that you think kids would enjoy, we'd sure appreciate your thoughts. We'd also like to spend a day or two in Denver, going to the zoo, the aquarium, or any other fun places you think we shouldn't miss. Somewhere along the trip, we'd like to do a half-day mild rafting trip. Also, if there are any other really interesting ideas anyone has for stops along the way (for example, if there's a really interesting cave tour, or mine tour, or whatever), we'd love suggestions. Since we're from South Florida, which is the only place my kids have ever lived, everything will be a new experience for them. Finally, I heard that some of the chuckwagons are lots of fun, so if anyone has any particular suggestions in that department, we'd love it if you passed them along. Thanks very much.
