TUAW:

Since it’s almost National Parks Week in the US(April 21-29), we’re seeing some iOS apps offered for free that normally have a cost to them. I’ve already mentioned the Chimani series of National Parks guides, and now I want to call your attention to Fotopedia National Parks, a universal iOS app that contains almost 3000 superb images taken by renowned photographer Quang-Tuan Luong.This app is not a detailed guide to the National Parks, but rather the equivalent of a coffee table book filled with dazzling photographs.

This app is two of my favorite things – free and about National Parks.
