I'm sure you don't need suggestions, but a couple of things I enjoy when I'm in Jasper are taking the Tramway up the mountain, Maligne Lake, and Miette Hot Springs. If you enjoy golf the course at Jasper Park Lodge is very nice. Watch out for Elk in the park, they are usually everywhere, and also watch out for other tourists, they will stop suddenly when they spot wildlife. Enjoy your trip and post some pictures!
