These sections are popular with fans who want to enjoy the full atmosphere of Petco Park without paying lower-level prices.  Location + Details  Upper Box and Upper Reserved seating is located on the highest seating tier at Petco Park, with sections numbered in the 300s.  These sections stretch across the entire upper deck, running from the right field corner across home plate to the left field corner. Because of the height of this level, fans will be farther from the field but will enjoy a panoramic view of the ballpark.  Upper Box vs Upper Reserved  Each upper deck section is divided into two seating types.  Upper Box  Located within the first six rows of each section    Closer to the field and entry tunnels    Typically more desirable due to the better viewing distance    Upper Reserved  Located in rows higher than Row 6    Usually among the cheapest tickets available for events at Petco Park    Farther from the field compared to Upper Box seating    Fans who want the best seats in this level typically look for Upper Box rows, as they provide a slightly closer view of the action.  Views from the Upper Deck  Because this level sits at the highest point in the stadium, views of the field will be among the furthest from the action at Petco Park.  However, the elevated position allows fans to see the entire field and stadium layout, which some fans prefer for following defensive positioning and overall game flow.  Sun & Shade  Most Upper Deck seats are exposed to the sun during day games.  Some shade can be found in the upper rows of sections along the left field side, particularly during later portions of afternoon games.  Seats on the right field side offer a better view of the main video board in left field, but they also tend to receive more direct sun exposure.  Nearby Attractions  Despite the distance from the field, the upper level still offers several nearby food and drink options.  One popular spot is the Stone Brewing Beer Garden, located just outside Section 309, where fans can grab craft beer while enjoying views of the stadium.  For a unique ballpark setting, consider sitting near Section 328, which sits beside the historic Western Metal Supply building, one of the most recognizable architectural features at Petco Park.
