Traveling on route 2 the Trans Canada Highway, traveling west to east, is left to right on the Moncton Area map. You can take the Magnetic Hill exit, it is also the Magic Mountain Water Park, and you will see Petro Canada Gas station and McDonalds. It's the only exit like this. Follow Mountain Road (route 126) all the way in until you can follow the Moncton Hall map, it should be easy from there.
