Gardens below the Boulevard des Pyrénées by mikey_e
The gardens under the Boulevard des Pyrénées are my favourite gardens in all of Pau. These are the most impressive, I think, because they climb the steep slope up from the river and the railway and include a wide variety of semi-tropical plants. There are palm trees and plenty of shrubs, but, given that this is meant to be more of a hiking trip than a walking garden, there are not many flower beds. On a hot summer day, a trip to these gardens is perhaps the best thing that you can do, as the shade provided by the trees is very much welcome, although the abundance of water may make it more humid than expected.
