Medina Lake is the deep, clear Hill Country lake closest to San Antonio’s northwest side: a long canyon lake between Lakehills, Pipe Creek and Mico, with limestone bluffs and water up to about 150 feet deep. Its dam was finished in 1913, and at the time it was the largest dam in Texas. When the lake is up, it is one of the best surf and ski lakes in South Texas.
The lake is about 40 miles northwest of San Antonio, roughly 45 minutes from Loop 1604. Medina is an irrigation lake with a small watershed, so its level swings more than most. Big Hill Country rains have brought it back up in 2026, and we will always confirm the best launch spot for current conditions when you book.
MasterCraft surf boats for 12 to 18 people, three-seat Sea-Doos, a Kawasaki stand-up jet ski and a full rack of water toys, all ready at the lake when you arrive. Book online in a few minutes, or call or text 888-205-7119 any day from 7am to 10pm.

Medina’s ramps open and close as the water rises and falls, so check which ones are usable the week of your trip.
Use the deep main lake. The main body near the dam is wide and very deep, with plenty of room for surf passes and tubing.
Cruise the canyons slowly. The upper lake narrows into a winding canyon. Take it at a relaxed pace and enjoy the cliffs.
Watch for hazards when the lake is low. Lower water exposes old docks, trees and rock ledges. Slow down near shore and in coves you do not know.
Surf early. Mornings are usually the calmest, before the wind and weekend traffic pick up.


Deep, clear water makes Medina a great surf lake. A MasterCraft surf boat rental seats 12 to 18 people and throws a clean wave on the calm main lake, and a couple of Sea-Doo jet skis are a fun way to explore the canyons. Add tubes, wakeboards and a floating lily pad, or book a captained charter so nobody has to drive. Everything is ready at the lake when you arrive, and life jackets are available for everyone on board.
Canyon Lake is about an hour northeast, and Lake Dunlap, Lake McQueeney and Lake Placid sit along the Guadalupe River east of the city. See our San Antonio boat rentals page, or browse every lake we serve on our destinations page.
