Be sure to check out Big Spring if don't mind the drive - it's about 5 hours away but I can promise you it is well worth the drive. Just gorgeous. I always fill up my water bottles there when I am riding the ATV. Delicious water. It is near Island Park. Just to the west is the St Anthony sand dune area. Just unbelievable at sunrise/sunset. The views change constantly so you are always in for a treat. A wide angle or medium telephoto will get you awesome photos. Also nearby is Two Top Mountain. It's a MUST see. It's about 8500 feet to the top. Have to go by ATV in the summer or snowmobile (during winter). There are places to rent those (about $250 a day). If you go stop at Ernie's and get a brown bag lunch to take with you (they give you everything you need for a full day outside). At the top of the mountain the views are beyond heavenly. Sitting up there alone will be a surreal experience. Of course, if you go at sunrise or sunset, the views will be only be enhanced that much more. If you stay after dark, the city of West Yellowstone is beautiful - the lights and everything down below. It should be a bucket list for outdoor photographers. I go several times a year and the views are different every time. I generally fly my TBM into Yellowstone airport and rent an ATV - forget a car. You don't need one. ATV's are legal on all roads and they are more fun. Depending on the time of year, you can pick and photograph Huckleberries growing in the wild - bring a close up lens set, macro lens or an Elpro 52. You mentioned snakes in your posting but I've never encountered one - not even a Western Diamondback. Also the area nearby is one of most concentrated for Grizzlies. But please, don't despair. I've never seen or heard one moving in the trees in the years that I've been going out there. I've camped out over night, etc., just never encountered any. Be advised that even during summer months early morning and evening will be cold. So dress warm in layers. It goes without saying that there are plenty of Moose to be seen, sometimes Buffalo, so bring a telephoto if you want to capture pictures of wildlife. If you like chasing bird life, there are terns, cormorants, bitterns, plovers, rails, coots, grouse, etc. Bring your imagination and desire to explore and you will be rewarded handsomely.
