Located in San Diego, Mission Bay Aquatic Park is the biggest water park in the world, a heaven for watersports enthusiasts, kids, families, and regular folk looking to enjoy a day on the water. There is kayaking, paddleboarding, sailing, water skiing, kite surfing, and much more. And outside the water there are wonderful hiking and biking trails, barbecues, picnic areas, bonfires on the beach, and anything else you can think of. There is also a very special treat: During the day, the water sometimes turns red and at night it can glow a bright neon blue due to the large presence of bioluminescent algae. While swimming in the glowing waters is safe most of the time, there are times when the algae emit toxins that are damaging to human health. If you cannot swim, take a kayak and paddle around surrounded by the magical glow.
