With summer in full glory, the time is right for a rooftop gathering. The verdant spaces we've highlighted here sit atop first-rate hotels and venues, perfect for planners who want to stay above it all.

Hotel Chinzanso Tokyo

After undergoing a $90 million renovation and rebrand, the 15-story, 260-room Hotel Chinzanso Tokyo now invites groups to gather in the Serenity Garden, an impressive 17-acre rooftop oasis that features cherry blossoms in spring, fireflies in summer, a riot of colors in fall and camellias of all kinds throughout the winter.

Baltimore Convention Center

The third-floor terrace at the Baltimore Convention Center became a "green roof" in 2010. More than half of the space is made from drought-resistant vegetative roofing, but it also houses on-site chef Gerald Infantino's herb garden. The terrace offers a total of 15,000 square feet of function space.

Drake Hotel/Toronto

Sky Yard, the rooftop garden at the 19-room Drake Hotel in Toronto, Ontario, is a chic urban oasis with a built-in beer garden and fire pit. Two stories up, the space can accommodate up to 100 guests in the winter and 150 during warmer months.

Peninsula New York

In Midtown Manhattan, the 239-room Peninsula New York's Salon de Ning rooftop garden offers glittering, panoramic views of Fifth Avenue from 23 stories up. The space can accommodate up to 250 people. 

Hotel Wilshire/Los Angeles

The Roof on Wilshire, atop its 74-room namesake hotel, opened in 2011 and captures the essence of L.A. perfectly with its cool cabanas, chill colors, inset pool and sleek modern design. This seventh-floor perch can host up to 100 and offers a menu from acclaimed celebrity chef Eric Greenspan. 

W Washington D.C.

The 5,000-square-foot P.O.V. Roof Terrace on the 11th floor of the 317-room W Washington D.C. is a gawker's delight, given all of the national monuments below. Cocktails arrive from two bars paneled in fresh green grass that heighten the outdoors vibe.

The Joule/Dallas

The 120-room Joule will complete a $78 million expansion this summer that will grow its room count to 161 and refresh the 3,300-square-foot rooftop garden terrace called the Joule Pool. The airy, sophisticated space features a retractable roof, a climate-controlled pavilion with downtown views, and a majestic Main Street-facing glass elevator entrance.
