Grand Geyser is located in the Upper Geyser Basin, just a short walk from Old Faithful. Grand is considered to be one of the most spectacular geysers, with at least a 75-100 foot tall main plume. One book calls Grand the tallest predictably erupting geyser in the world. Eruptions can last from 10-30 minutes, but are not nearly as predictable as Old Faithful. It usually erupts every 9 hours, plus or minus 2 hours. You might therefore have to wait as long as 4 hours to see Grand, but it is definitely worth the wait! Go to the visitors center in the Upper Geyser Basin, and they will give you the most recent prediction, which could be more accurate than the one listed above.
