Mt Hood & Columbia River Gorge are beautiful, great hiking.
In June the area should be in full bloom, so check out some of the public gardens in and around Portland.
I think the rose festival is in June. In any case, if you enjoy gardens I can suggest three in Portland - the rose garden, the classical Chinese garden and the Japanese garden. Also, check out the Pittock mansion.
