It's impossible to tell how immense the Coloma rose garden is, until you start wandering through it. Each hedge holds the passageway to another garden of colourful roses – Picture the Queen of Hearts' garden in Alice in Wonderland and you'll be on the right track. On average, there are 200,000 roses in bloom throughout the season. The gardens are organised by geographic region. Of course Europe is the most represented of continents, but there are roses from around the world. We were thrilled to find that even Canada is dedicated a tiny corner in Coloma. There are pergolas and trellises for climbing roses, some statuary and well placed benches so you can literally stop and smell the roses. At the far end of the rose garden, there is also a lookout tower so you can admire the colourful landscape from above. There is little shade in the rose garden itself so be prepared if it's a hot summer day. You can escape the heat by popping back under the shade trees in the main park. You don't even have to worry about losing your ticket – there aren't any. Coloma Garden is completely free to visit.
