MISSOULA, Mont. -

It may have been a rainy Sunday in Missoula but that didn't stop folks from 'getting lost' in the Missoula Maze.

Organizers Christina and Earl Elligson tell NBC Montana this is the fifth year they have stacked hay bales and created twisting and turning trails through a one-acre corn field in the west Missoula valley.

“It's kind of a fun fall family event and we get people of all ages - families with babies and all the way up to grandparents and everybody in between,” says Earl Elligson.  “Everybody seems to have a lot of fun.”

The maze features a tower, slide and clues to help folks through and Earl Elligson says this year they will change the maze half-way through the season to give visitors a new surprise.

“A lot of people, they are just all smiles because they get lost and they have a good time doing it,” he chuckles.  “Every year we'll kind of add some new ideas to those harder parts that we know work well and it just really makes for a good maze that's better and better every year I think.”

The Missoula Maze features the large corn maze, a mini-maze, obstacle course, puzzle maze and even treasure hunts, plus Elligson says there are even more fun events to do in October.  

“We do a night maze starting in October and that's a lot more challenging,” he says.  “We take away all of the clues out in the maze and so basically you just have to go and see what happens.”

A new feature this year is there are three entrances to the maze rather than one.  

“One is just completely a dead end, another one just kicks you out the side of the maze and you didn't solve anything and then the last one is really the right one,” says Elligson.  “With our new wild west theme we have a couple of horses basically out in the corn field, they're pulling a covered wagon and part of my favorite part is just coming up with new designs that are fun and difficult.”

Elligson says folks should check out the maze sooner than later; he says they get extremely busy closer to Halloween.  

He tells us 10 percent of the proceeds raised go to Mountain View Elementary School and the rest go towards creating next years’ maze.

If you haven’t gotten your Halloween pumpkins yet, the maze’s patch will also be open next Sunday September 29.
