The days are getting warmer, brighter, and longer, and that means summer is on its way!

We’ve already fired up the barbecue and started planning our summer holidays, but what we really can’t wait for is to spend more time enjoying the great outdoors.

Since June is Great Outdoors Month, we’ve pulled together the Firefly Great Outdoors Instagram Challenge to inspire you to get outside and enjoy the wonders of nature.

The challenge is simple: we want you to post one photo each day for the whole month of June, each one inspired by the great outdoors.

California is known as the Golden State for many reasons — the seemingly endless sunshine, the fields of yellow wildflowers that appear every spring, the history of gold mining in the state, and of course, the golden sunsets.

The state itself is as diverse a place as its official nickname. California is the most populated US state and home to 3 of the country’s largest cities as well as 36 National Natural Landmarks, 2 UNESCO World Heritage Sites, 280 state parks, and 149 federally designated wilderness areas.

This vast state has everything you could want for an epic nature getaway, from rugged mountain ranges to sandy beaches plus plenty of opportunities for wildlife spotting.

Deciding where to go first might just be the hardest part of planning a visit to California, so to help you out we’ve made a fun quiz to give you a personalized travel recommendation.

Book lovers are notorious for seeking out bookish places to visit on holiday. From the famous stacks of historic bookshops to the homes of celebrated writers, there’s no shortage of travel selfies — or should we say, shelfies — to be found across social media.

Rather than turning to social media for inspiration this World Book Day, we’ve turned to the history books, or at least our own bookshelf. We’ve scoured the 8^th edition of UNESCO’s World Heritage Sites to compile a list of historic libraries every book lover should visit at least once.

Here are ten beautiful historic libraries to inspire your literary wanderlust.
