Like most things in Texas, Austin’s Lake Travis is big, at spots stretching as far as 63 miles long and four miles wide. Nor is there any skimping on things to do, with scuba divers flocking here from across the country for the lake’s crystal-clear water and spectacular summer weather. Or, take flight in a parasail, lure in a tasty 10-pound bass, or rent a boat or wave runner at Lakeway Marina. Hourly rates start at $75.
