I would like to know if it is possible to walk far along the beach either way? My husband and I like to walk off the lovely food we eat at Couples and were disappointed that the CTI beach was not very long.
You can walk for miles. We stayed in the newer section on the South side so we walked that portion a lot. Plenty of bars and gift shops along the way as well as Margaritaville and other scenic stops. Lots of people selling stuff and you will be offered everything imaginable. We enjoyed it though. To the North it is mostly other resorts but you can still walk a long way before it gets rocky close to the island.
Enjoy the beach walk going either direction. Cosmos Restaurant/Bar is an interesting locally owned establishment just past Beaches. DO NOT walk the beach after dark, there is a reason the hotels have beach security.
You are going to love CSA. The beach is the best I've ever been to and you can walk in either direction for a long time. Lot of local flavor both ways. Make sure to take a nice night time stroll across the CSA property because it is so beautifully lit at night. So romantic. Have a blast!
