Fastest still water fishing in the Park is, you guessed it, Beula Lake. Riddle Lake is not far behind. Both can be fished from shore, but getting out in a float tube results in best fishing. Beula is a longer walk at 2.75 miles, whereas Riddle is just under two miles over easier terrain. No complicated flies or strategy are needed for both these small lakes well populated with Yellowstone cutts. Your favorite bead head nymphs, small leech patterns, speckled dun life cycle, and damselfly life cycle patterns will produce.
