I really like hiking in the mountains during the summer. There are few bugs and low humidity. The main drawback to a summer in the mountains is the intense sun.
Lake cabins are always a favorite as I like to fish and relax. I also like the evening campfires when camping or staying at a lake cabin.
I've never been to Alaska. I think a summer cruise along the Alaskan coast would be nice. I also like the idea of a summer cruise in Northern Europe.
Waterparks have always been my favorite because I love to swim and go on water slides and rides. Spend some time in Wisconsin Dells if you like waterparks as much as I do.
I'm a big fan of the mountains in the summer. I really enjoy hiking. Great views, clean air, good exercise, fewer bugs at higher elevations. Rocky mountains are wonderful, but I also had the chance to take a summer vacation to Switzerland and that was one of my favorite vacations of all time. I really want to return to Interlakken Switzerland at some point in my life.
