So, once you've wandered around Pike's Place Market, catch a ride over to the University area (yes, Husky grounds!) where you can rent a kayak (Agua Verde Cafe & Paddle Club) to paddle around Portage Bay, into Union Bay and through parts of the Washington Park Arboretum. If it's a warm day, it will be the perfect afternoon activity and a unique experience of being in the city and yet removed from the hustle and bustle as well...and, lots to see (beautiful waterfront homes and houseboats, the Montlake Draw Bridge, particularly friendly water fowl, and lots of people hanging out in and near the waterfront). Upstairs from the Paddle Club is a great little Mexican Cafe...yummy food and perfectly blended drinks!
If you want to spend more time outdoors, and like to people watch, the evening hours are fun at the Seattle Center. From downtown, it's a quick ride on the Monorail which ends in the heart of the Seattle Center. Between the Space Needle, the amusement park, the live music almost always happening there and the International Fountain, there is always a steady stream of entertaining sights and sounds!
