Garden Travel


Since 1998, HPSO members have traveled together to international garden destinations in England, Wales, Scotland, Ireland, France, Italy, the Netherlands, Belgium, Germany, Spain, Portugal, Madeira, South Africa, New Zealand and Japan. New destinations - Denmark, Sweden, and Australia are in the works.

Closer to home, our U.S. tours have featured gardens in Washington and California. The Puget Sound Islands tour series has highlighted the gardens of Whidbey Island, Vashon Island, and Bainbridge Island.   Trips to the East Coast have also been popular. Recent destinations include New York City, the Hudson Valley, Savannah and Charleston.


HPSO tours have distinctly garden oriented focus that supports our mission to provide great horticultural education opportunities for our members. Tours include a variety of cultural and historical sites that round out the landscape. Trips vary in duration, and they are filled with activities. HPSO tours represent an excellent value for the money.

Tour prices typically include double accommodations, motor coach and professional guide, tour gratuities, many meals, and admission to all gardens and other sites along the way. Participants are responsible for their own transportation to and from the tour's start and finish points, including airfare.

Tours are conceived, researched and led by HPSO members with experience in the relevant destinations. HPSO works through excellent international tour companies that are responsible for booking arrangements. Tours are open exclusively to HPSO members.


Tours are announced to members through emails, our member magazine the HPSO Quarterly, the HPSO Travel Interest Group (a.k.a. HPSO Travel Club), and on this web page.

HPSO Members who wish to have advance notice about tours must join the HPSO Travel Interest Group.  There is no fee for joining the group and no obligation to attend extra meetings. Travel Interest Group members receive earlybird registration privileges for HPSO tours. Contact the HPSO office to join and be on a travel-interest mailing list.

"A Nordic Adventure: Gardens & Castles of Denmark and southern Sweden"
May 25 - June 6, 2021 

SORRY. THIS TOUR IS NOW FILLED.   Contact us if you would like more information or if you wish to be placed on the waiting list.

Embark with HPSO on a new adventure to two nations often cited as the happiest in the world. Our tour begins in Copenhagen and ends in Stockholm. We explore gardens and sites of interest on two of Denmark’s main islands, Zealand and Funen, before we cross the Øresund straight into Skåne, a former part of Denmark that became Sweden’s most southern province by the treaty of Roskilde in 1658. After we enjoy Skåne, we travel along the west coast of Sweden, including the cities of Helsingborg and Gothenburg, before we take a scenic train journey across the country to Stockholm, the capital city. 

The Atlantic Gulf Stream provides northern Denmark and southwestern Sweden with a fairly mild climate, allowing beautiful gardens to thrive. Included on our tour are visits to the best private and public gardens in this region plus Tivoli Gardens and the Malmo Flower Festival which is held just every two years. Also included are visits to palaces, castles, historical sites, and various museums such as the Vasa Museum, the Viking Ship Museum, Hans Christian Andersen Museum, and the ABBA Museum. We might even see the changing of the guard at The Royal Palace in Stockholm and see other festivities on Sweden’s National Day, June 6th! Join the fun on this comprehensive and fabulous tour as we follow in the footsteps of Nordic royalty.

Join HPSO on a new adventure to some of southern France’s most extraordinary regions. In the Dordogne river valley, in Languedoc- Roussillon, and in Provence, humans have left their mark over the ages — from cave paintings in the Paleolithic age — to aqueducts and amphitheaters in the Roman period — to castles and fortified towns in the Hundred Years War — and now to beautiful gardens created in our modern era! This special part of France has all of these things plus a countryside full of world-class vineyards, picturesque villages and chateaux, and a stunning coastline. Our two-week tour begins in the heart of Aquitane in the vibrant city of Bordeaux (one night) and ends near Marseille in Aix-en-provence (two nights). Along the way, we’ll stay four nights in the heart of Dordogne (in Sarlat), then two nights each in Toulouse, Montpellier and Fontvieille. Our tour includes visits to private and public gardens, the Lascaux caves, troglodyte cliff-dwellings, chateaux, medieval towns (including Carcassonne), wineries, and afternoon cruises on the Dordogne river and the Mediterranean’s La Calanques on the southern coast! Join us on this fabulous adventure of this mystical and picture-book area of France.

A Garden Sojourn Across Northern Italy: From Liguria to Veneto

May 13-23, 2022

SORRY.  THIS TOUR IS NOW FILLED.  Contact us if you wish to be placed on the waiting list.

Join the fun on this 11-day (10-night) sojourn across northern Italy. We begin our tour in Liguria, the Italian Riviera, on the Mediterranean coast. Next, we travel into Piedmont, known for its incredible wine, food, and the home for Italy’s finest chocolatiers - no doubt influenced, in part, from past French dominance. We then cross over into Lombardy, now sensing a melding of some Austrian-Germanic influences which get even stronger as we venture north into Trentino. We end up in Venice with its own unique twist on everything Italian.
Our tour includes fabulous gardens, food and wine adventures, villa and castle excursions, and visits to Italy’s greatest lakes - Lake Maggiore, Lake Como, and Lake Garda. Join us as we make our garden sojourn across northern Italy!

SORRY.  THIS TOUR IS NOW FILLED.  Contact us if you wish to be placed on the waiting list.

The area surrounding the northern Adriatic Sea is one of the most diverse regions in the Mediterranean - from coastal marshes and plains near Venice to the Julian Alps in Slovenia to the myriad of islands and fjord-like coast of Croatia. This is a land of contrasts. But, the diversity doesn’t end with geology. This region has had centuries of different cultures, religions, and civilizations converging, sometimes merging to create something new while other times ending in brutal conflict. It is a beautiful area, too - often referred to as the eastern riviera!
Our 17-day (16-night) adventure begins in Venice (Italy), then explores the highlights of Slovenia before moving down the rugged Croatian coastline and ending in Dubrovnik. While not a garden-heavy tour, our dates are timed to encounter the best of the wildflower bloom in the region, including a botanical hike near Lake Bohinj during the annual Slovenia Wildflower Festival.  We will see Alpine lakes (including famous Lake Bled), cosmopolitan cities and museums, castles, caves, Roman ruins and antiquities, wineries, medieval hilltop towns, ancient churches and cathedrals, national parks, and coastal resorts!  We will experience the magic and diversity of this northern Adriatic region on our HPSO adventure. Please join us!
