Cabin Fever

Well, the sun has finally decided to peek out from behind the clouds and the weather seems to be almost decent now. I've been suffering from cabin fever since about, oh July of last year. I'm determined to spend a lot of time outdoors this summer and I thought I would try to recruit some help. I'm looking for fun things that involve walking (i.e. hiking, climbing etc.), water (swimming, kayaking etc.), and NOT INDOORS. I would like things that are day trips and a few overnight spots are good too. So far I'm planning on going to Multnomah Falls, Ape Cave and possibly Belknap. I would be so grateful for anymore ideas or places to try. This is Carpe Diem to the max! ( I warned you that I've been feverish :-D ).
