We've curated just a few excursions on this page, selected for popularity and walkability (once you're there, of course). For more ideas, check out the Austin Chronicle's Best of Austin list, accessible activities curated by accessibleGO, a list of Austin activities from U.S. News, and Eater's Essential Austin Restaurants.
A cab or rideshare will be your fastest option if you don't have your own vehicle, but in case you'd like to try public transportation, there are bus stops on Camino La Costa, the street about one block east of the hotel. You can find a trip planner on CapMetro's website.
Easy Food near the Hotel
Not a field trip per se, but if you're hungry and want to expend minimal effort, walk a few hundred north to Hideaway Kitchen and Bar. If you have a ride, you can find expansive outdoor seating and excellent food trucks at Meanwhile Brewing Company.
Another option is to use a food delivery app, which would let you order from some of Austin's best restaurants and have it delivered to your hotel. There are several such companies working in Austin, so you may want to try several apps or check the restaurant website if you can't find your desired restaurant on a given app. In general, Doordash and Ubereats have pretty good coverage, with Ubereats offering the longest delivery range (i.e., from restaurants that are relatively far away). For non-food items like some Longhorn merchandise or your favorite shampoo that you forgot, try Favor. If delivering directly to your room, be sure to include your room number in your delivery address and add a note that says to leave the delivery just outside your hotel room door.
