7 Best Sights in Portland, Oregon

This glorious patch of greenery within Washington Park comprises three terraced gardens, set on 4½ acres, where more than 10,000 bushes and some 610 varieties of roses grow. The flowers, many of them new varieties, are at their peak in June, July, September, and October. From the gardens you can take in views of the Downtown skyline and, on clear days, the slopes of Mt. Hood. Summer concerts take place in the garden's amphitheater. It's a pretty but hilly 30- to 40-minute walk from Downtown, but it's also pretty easy to get here by bus.

In a twist on the Joni Mitchell song, the city of Portland and private donors took down a parking lot and unpaved paradise when they created this wonderland near the Pearl District and Old Town/Chinatown. It's the largest Suzhou-style garden outside China, with a large lake, bridged and covered walkways, koi- and water lily–filled ponds, rocks, bamboo, statues, waterfalls, and courtyards. A team of 60 artisans and designers from China literally left no stone unturned—500 tons of stone were brought here from Suzhou—in their efforts to give the windows, roof tiles, gateways (including a "moongate"), and other architectural aspects of the garden some specific meaning or purpose. Also on the premises are a gift shop and an enchanting two-story teahouse, operated by local Tao of Tea company, overlooking the lake and garden.

One of the most authentic Japanese gardens outside Japan, this serene landscape unfolds over 12½ acres of Washington Park, just a short stroll up the hill from the International Rose Test Garden. Designed by a Japanese landscape master, there are five separate garden styles: Strolling Pond Garden, Tea Garden, Natural Garden, Sand and Stone Garden, and Flat Garden. The Tea House was built in Japan and reconstructed here. An ambitious expansion designed by renowned Japanese architect Kengo Kuma added the Cultural Village, which contains a tea garden café, library, art gallery, and gift shop. The east side of the Pavilion has a majestic view of Portland and Mt. Hood. It's a pretty walk to get here from Downtown, but the garden is also easily reached by bus.  Knowledgeable volunteers guide daily public tours, which are free with admission; reservations are required (and can be booked online).

For much of the year, this nearly 10-acre retreat near Reed College is frequented mainly by bird-watchers and those who want a restful stroll. But starting in April, thousands of rhododendron bushes and azaleas burst into flower, attracting visitors in larger numbers. The peak blooming season for these woody shrubs is May; by late June the show is over.

Some 12 miles of trails that connect with others in Washington Park and Forest Park wind through the 189-acre arboretum, which was established in 1928 and contains more than 2,000 species of plants and one of the nation's largest collections of coniferous trees. Pick up trail maps at the visitor center. Guided 90-minute tours ($5 suggested donation) are offered at various times. Also here are the Winter Garden and a memorial to veterans of the Vietnam War.

The "City of Roses" moniker started here, at this park that harks back to another time. The city's oldest (1913) public rose garden (and the only sunken one) houses about 5,000 plantings of roses. The daunting task of deadheading all these flowers is covered in classes taught to volunteers. The bandstand is a historic landmark, and the last of its kind in the city. This 16-acre North Portland park also contains an ornate historic fountain, Italian villa–inspired community center, playground, wading pool, tennis and volleyball courts, and picnic tables.

Owned by the Catholic Church, the National Sanctuary of Our Sorrowful Mother, as it's officially known, displays more than 100 statues and shrines in 62 acres of woods that adjoin Rocky Butte Natural Area. The grotto was carved into the base of a 110-foot cliff, and has a replica of Michelangelo's Pietà. The real treat is found after ascending the cliff face via elevator, as you enter a wonderland of gardens, sculptures, and shrines, and a glass-walled cathedral with an awe-inspiring view of the Columbia River and the Cascades. There's a dazzling Christmas Festival of Lights (late November and December, $14), with 500,000 lights and more than 160 holiday concerts in the 500-seat chapel, and an indoor petting zoo. Daily masses are held here, too.
