This lovely little historical village is a MUST visit. It has several historical buildings (about 8 or so) that give you a great snapshot into Sanibel's past. The facilities are well laid out, you can take a self narrated tour they have small recording machines with a 3-5 minute outline of the building in each unit or you can take one of the guided tours. They have two tours a day - 11am and 2 pm. Cost to enter the village is $5 for adults and kids are free - there is not additional charge for the guided tours. The volunteers there are so knowledgeable and so helpful.
Make sure you take time to visit - you can zip through the whole place in 45 minutes but I suggest you spend about 1 1/2 hours there - you won't regret it.
