Coronado's Active Lifestyle Coronado is known for its active lifestyle. The weather is great year round and we spend a lot of time outdoors. Coronado Island is 7 miles all the way around with San Diego Bay on one side and Coronado Beach on the other, offering the opportunity to be active and enjoy the beautiful scenery all over the island. Wherever you go on Coronado, locals and visitors can be seen walking, biking, swimming, golfing, running, boating, skating, kayaking, surfing, paddling – well, you get the idea! Fun, fun, fun in the sun!
