There is just one word to use when describing the hiking trails that I will always remember when I think back about Minnesota; mosquitoes! The swarms of mosquitoes along the hiking trails were the worst that I have ever experienced in my life. We had planned on spending the morning hiking on the 7+ miles of trails throughout the park before finishing off our weeklong road trip and heading back to Denver, but the bugs put a halt in those plans. We woke up at 7am and I was ready to check out the bluffs and Mississippi River Valley. The park provides a well marked trail system with maps at the ranger station and several maps along the trails.
