“The bugs are awful; do not go backpacking in Yellowstone until September!” But that is a myth, because if you know what you’re doing, you needn’t be deterred by Yellowstone’s greatly exaggerated population of mosquitoes, horse-flies, deer-flies and other biting insects.
In fact, if you choose your route carefully based upon the exact time period and the specific route choice, the mosquito “problem” will seem over-rated. For example, on our Big Wild Adventures guided Yellowstone hiking tours, we are extremely cognizant of the timing of mosquito hatches as they occur in specific geographic areas of the park. For example, we would never schedule a Southwest Yellowstone Bechler Waterfall Wonderland trip in June or early July, because that’s wet country and early summer mosquito biomass can — depending upon the weather — be reminiscent of the Alaskan tundra. On the other hand, our guided Yellowstone backpacking trips in the drier northern and northeastern parts of the park are often ideal, with bugs at bearable levels any time from late May until the autumn snows fly! In other words, because we know the Yellowstone backcountry so intimately, you can count on our schedule always giving you a great opportunity for a great wilderness experience because we know the optimal times for avoiding the densest mosquito situations for each unique geographic area of this sprawling wonderland.
Nonetheless, on mid-summer treks anywhere in the Rocky Mountains, it pays to be prepared, not just for mosquitoes, but also for rapid weather changes plus the almost unbearable natural beauty that you’ll experience while backpacking in Yellowstone, the world’s first national park.
