Hiking is a favorite activity of our family, though one we don't get to do as often as we'd like. We are always on the lookout for regional trails to check out when the hiking bug bites.
The Sierra Club has recently launched a new site, Sierra Club Trails. It houses descriptions of trails across the country - which you can rate and add your own feedback on. Best of all, it's a wiki, so if you see things that are missing (like I know there are more than six trails in the state of Indiana--heck there are probably at least that many in Brown County alone, which stands out in its absence!) you can add your information to the site.
And it's more than just "this is a nice wooded trail." A Sierra Club rep told the Green Phone Booth:
So if I post a trail in, say, Yosemite, and you've been there recently and saw that part of the trail is really muddy, or the bugs are bad this time of year, or if camping spots are getting really popular and should be reserved in advance, you can update that.
The site is very easy to use and search for the trails you need. (Note to techies: It needs scripts enabled, or you're completely out of luck, especially in FireFox.) It's definitely worth bookmarking for future use. Thanks to the GPB for pointing this site out!
