River walk is 15 miles long...and approx 5 miles of downtown included ..best way to enjoy it is to take boat/cruise which is approx 35-40mins long and covers 1.5 miles of along with narrated tour...which costs apprix $12 for ages 6-59.
Excuse me, I just walked with my husband next to the river. I don't know how to say the prices, but it's very nice.
