We'll be arriving in Manzanita the evening of July 27th and flying home from Portland late afternoon August 1st. There will be about 30 of us (all ages) staying in 2 beach houses and most of our time will be unstructured. What are some really fun activities/must-sees for either our immediate family (kids age 14, 17 and 20) or a larger group within a few hours drive of Manzanita? My daughter likes lighthouses and hikes, my son golf, my hubbie going through art galleries and antique shops and I enjoy taking photos, doing things I wouldn't do at home like renting horses and visiting museums and other popular attractions. I'm wondering if the Oregon Coast Aquarium in Newport is worth the 2+ hour drive, if anyone's been to the Tillamook Forestry Center and the best itinerary for 4 l/2 days. Should we wait and visit Astoria on our way back to Portland Aug. 1st? If so, is it worth driving across the border into Washington and visiting the area around Long Beach? I'm also looking for suggestions of things to see around the Portland/Vancouver (where my sister-in-law lives) area for about 3-4 hours before we need to be at the Portland Airport. Thanks for the help!
