Nice landscape....I would love to walk or hike around there. Take your kids on small hikes...go for as long as you know they can tolerate the walk - walk halfway somewhere and turn back. That's what my son does with his 18month old - they hike in the BC mountains and he loves it.
Take advantage of the freshness around you. I forget how old your youngest one is. But I know they'd love discovering everything from sticks and stones to puddles and flowers. :)
