Re: Mt. Hood spots (Oregon)
I grew up in Welches. Beautiful up there. Funny, when I was a kid all I wanted to do was get off that mountain, now I'm 28 and I find myself driving up there any spare moment I get.
So, I don't know what you want to do exactly, but if you're just wanting to go exploring around and stuff like that, there's a lot of places up there for that. I recommend Still Creek Road. It starts in Rhododendron, right off of 26 before the bridge just before the food and general/dairy queen, etc. It goes from there all the way up to Trillium Lake. Most likely the gate will be closed about 8 miles in, preventing you from getting all the way to the lake, but there are a lot of cool little spots along the way on both sides of the road. There's little river spots/waterfalls, camp sites, etc.
There is also Lolo Pass road in Zig Zag. Take it up about 7 miles or so until it splits right or left. If you go left it takes you all the way to Lost Lake (long drive and will be snowy for sure) if you go right it takes you over a little bridge and then some backroads around some camping sites and things like that. Kind of a cool little area.
Further East on 26 is a cool little road, I think it's road 36 ? It will be on the left hand side if you're going east and it's right before the highway takes a fairly hard right hand turn. If you go up that road, follow it all the way to the end (about 5 miles) and it will end up in a little parking lot/turn around area. Straight ahead of you will be a trail head that takes you about 600 feet or so to a really cool little waterfall. You'll also see that it splits off to the right and up a small hill. If you walk up that way a little bit, you'll come across a really cool old railroad bridge, and there is also a trail that goes god knows where, I don't know if you're a hiker or not. That "road" leading up to the bridge was the original highway before the new highway 26 was put in, it's pretty neat because you can see how old it is, and there are old concrete guardrails and stuff like that.
That's just a couple I can think of off the top of my head. There are a million little roads up there, and they're almost all really cool to explore. Basically any of the roads on the right or left of highway 26 once you get past The dairy queen in Rhododendron are cool to explore.
