Give yourself a whole hour or more for the Japanese Garden. Walk slowly. Take it all in. It's supposed to be serene, and being on a timeline messes with that. The park itself is huge, so maybe set at least a half day aside if you can hang with nature.

Ditto what others have said. There was a “hot dog” cart when we were there too. And take the free bus around the park to minimize the walking necessary. Have fun and check out the Roses!!!

Washington Park allows dogs but the usual rules apply: Dogs must be on a leash and clean up after them. Apart from that its a perfect place for the whole family.

No specific bike trails, but there are plenty of bikers on the winding roads through the park. Check out the park map.

Yes it is. Plan for some congestion and parking challenges on weekends

The Red line...avoid the parking morass (not always) and park elsewhere...Downtown, the burbs wherever any max line is...

P.S. The walk from the parking area to the top @ the Japanese Garden is steep. If your children are small-young or you have a stroller, suggest you use the shuttle, which is well scheduled.

I agree with Dan D. - it depends on your preferences. We enjoy staying in NW Portland in the Pearl District, because of the restaurants and accessibility to Washington Park. It's all so close you can hike then walk to lunch when you're done. We've been known to put on 10 miles without alot of effort. If you like the river, try staying by the waterfront. The Saturday market is always fun and there are loads of restaurants nearby. We usually stay at te Hilton as it's close to the river and shopping. If in the Pearl, we choose something that area. Transportation around the city is easy. No need for a car.

I didn't pay anything but we just walked around. There are several indoor spots that may have food but I didn't go into them I'm sorry I couldn't be more help.
