We are a hiking family, it is the one sport like thing that we both like, and now we are getting the kids involved too. Princess took her 1st hike at Round Top in Honolulu at 6 weeks old.
Buddy took his 1st hike in Pacific Grove at about 6 weeks, it was raining and since Princess wasn't even 2 years old yet she got to ride too.
Munchkin had her 1st hike when she was older, probably because it was January and really cold when she turned 6 weeks old. I think her 1st hike was at 1st landing state park, she went camping at Kiptopeke State park at 6 months, so I know we went hiking in the really hot weather then. I can't find any pictures of her hiking. Maybe I will find it later.
Scout had his first hike at 2 months old and hiked in Douthat State park and hiked lots in one week.
Now Daddy has started getting the kids backpacking and carrying all their supplies with them. I will let him do that on his own. I don't really need to do that one, day hikes are fine for me.
