Austin & the Hill Country

Everything in Texas is flat.
Until you leave the plane.

The Hill Country is not high – its limestone hills top out a few hundred feet above the rivers – so Austin's thrills come from what people have built on it and from the water that runs through it. These grounds start at 14,000 feet over a cotton field outside San Marcos, drop to the longest zipline in Texas above Lake Travis, to the treetops at Wimberley and the pocketed limestone of Reimers Ranch, and end where every Texan summer ends: in a tube on a 72-degree spring-fed river.

14,000FT · EXIT ALTITUDE

Fourteen thousand feet over a cotton field

Fentress is a grass strip between San Marcos and the cotton; the plane climbs twenty minutes to 14,000 feet. Then the door slides open, the Hill Country is a green map with the I-35 drawn through it, and you lean out.

Price

Direct only. Skydive Spaceland runs one of the busiest drop zones in Texas from Fentress, 45 minutes from Austin and an hour from San Antonio; neither GetYourGuide nor Viator lists a tandem here. Book prepaid for the lower rate. Photo: a tandem jump elsewhere, not Fentress.

The last of the five lines: two cables side by side, 2,800 feet across a cove of Lake Travis, from a platform 184 feet above the landing – the snack-bar roof. You reach it by hiking the equivalent of twenty flights of stairs.

Direct only, and weather-dependent. Tours are booked on the operator's site; the boat shuttle across the cove is part of the trip. At full pool (681 ft) the lake surface is about 220 ft below the takeoff – but Lake Travis often runs far below full, so the water is usually further away than that.

100FT OVER THE VALLEY

Ten lines over the cypress tops

Wimberley is the gentle version: ten lines from 200 to 900 feet, none of them terrifying, strung 20 to 100 feet over cedar and cypress with fifteen-mile views. It is the tour to take the nine-year-old on.

Reimers is a limestone band above a bend of the Pedernales, honeycombed with the pockets Texas climbers are raised on. The walls are short and steep enough that you feel every foot; the river is where you jump in afterwards.

Two and a half miles at 72 degrees

The Comal is the shortest river in Texas and the busiest: 2.5 miles of 72-degree spring water, a chute that shoots you round the dam, and half of San Antonio floating beside you on a July Saturday. One decision: bring the cooler?

Most tubes are rented at the river, not online: Texas Tubes, Rockin' R and Landa Falls line the Comal in New Braunfels and rent for the day. The platforms carry a guided float on the San Marcos and one Comal outfitter. The Guadalupe next door has the only real rapid, Hueco Falls, Class III at high water.

    Before you jump

    How high is the skydive near Austin?

    Skydive Spaceland San Marcos jumps from 14,000 feet at its Fentress drop zone, 45 minutes from Austin – about 60 seconds of freefall at 120 mph, then a five-minute canopy ride. You must be 18 and under 265 lb (surcharge from 220 lb). Prepaid tandems cost $229 on weekdays and $259 at weekends; it is booked direct, not through the platforms.

    What is the longest zipline in Texas?

    The Double Barrel Shotgun at Lake Travis Zipline Adventures: 2,800 feet across a cove of Lake Travis at up to 65 mph, the last of a five-line tour. The takeoff is at 902 ft elevation and the landing at 718 ft – a 184-foot drop – and riders must weigh 70–250 lb. The 3-hour tour costs $138 plus tax, direct.

    Can kids zipline in the Hill Country?

    Wimberley Zipline takes children from 9 years and 65 lb on ten lines 20–100 ft over the valley; Lake Travis has no age minimum but a 70-lb weight minimum. Under that, Twisted Trails in San Antonio has zip rails and a ropes course.

    Where can you go rock climbing near Austin?

    Reimers Ranch, 40 minutes west on the Pedernales: limestone walls up to about 50 feet with more than 200 bolted routes from 5.5 to 5.14. Guided half days with all gear are the most-reviewed adventure booking in Austin (395 reviews, five stars); park entry is $10 per vehicle.

    How long does tubing the Comal take?

    Two to two and a half hours for the 2.5-mile float from Comal Springs to the Guadalupe, in 72-degree water year-round, with the Tube Chute as the one rapid. Children from age 4; tubes are mostly rented at the river in New Braunfels. On GetYourGuide the guided BYOB float on the San Marcos is the most-booked option.

    Is Hamilton Pool open for swimming?

    Only sometimes. Travis County requires a reservation ($12 per vehicle plus $8 per adult) and closes swimming when bacteria counts rise after rain; the 50-foot waterfall and the grotto are open regardless. Jumping is not allowed.
