The Bill Williams River National Wildlife Refuge is found at the far reaches of southeastern Lake Havasu. Rumored to contain the largest surviving cottonwood-willow woodlands of the lower Colorado River, the Refuge covers 6,000 acres. Perhaps most importantly, the Bill Williams River serves as a comfortable refuge to over 300 species of birds and waterfowl. There are a number of endangered species currently in propagation, including the razorback sucker fish and bony-tail chubs, which are indigenous to the Bill Williams River. Additionally, the Audubon Society named the Refuge an area of global significance in 2011.

The Ria Formosa wetlands gained protected status in 1987, safeguarding this crucial breeding ground for wetland birds from tourism development. Thanks to this protection, the entire coast from Faro to Cacela Velha was able to avoid any urbanisation. A boat trip to one of Faro’s islands is perhaps the best way to visit Ria Formosa.

There are multiple companies offering wine tours to wineries in the Montpellier area.

One company organising tours of this kind is Montpellier Wine Tours.
