Once you have found the filter, all you have to do is post your image on Instagram with the hashtag #LagunaTime, and you’ll be in for a chance to win two passes to the recently opened waterpark.
Here’s a tip – the prizes are most likely to go for those who take the most inventive snap, so use that imagination and get creative.
The champions will be announced at random after the final treasure hunt, so stay tuned to Laguna’s social media pages.
The park opened just last week, and has the region's only 180-degree wave machine, The WaveOz 180 FlowRider, aka the ultimate surf machine.
Laguna is split up into four different zones, dubbed Surf, Relax, Slide and Splash, where people can either float around a lazy river or take on the heart-pounding AquaDrop.
Time Out Dubai recently went over to the waterpark when it opened, and we can safely say there is a ton of fun to be had, along with a lot of falling-off-surfboards.
Treasure hunt locations: The Beach, Outlet Village, Al Seef, Last Exit (May 18-19); City Walk, Boxpark, La Mer (May 25-26). Laguna Waterpark: From Dhs99. Open daily 10am-8pm. La Mer Central, Jumeirah 1, www.lagunawaterpark.com.
