In this paper we present a travel cost model combining revealed and stated preference data on beach use in Delaware and use it to value changes in beach width. We use an in-person on-site survey at seven bay beaches in the state. The analysis is in two stages. The first is a model for predicting the number of visitors at each site over a 12-month period based on an on-site count of visitors. The second is a single-site travel cost model that combines actual and contingent trip data. We estimate the loss for narrowing beaches to a quarter current width at about $5.00 per day at the beach and the gain for widening to twice current width at about $2.75 per day at the beach. The current width of the beaches is between 50 and 100 feet.
