Steph Curry's NBA championship celebration is STILL going on ... the 2x-MVP took a trip to a theme park in Northern California with his family on Wednesday to keep the good times rollin'!
TMZ Sports has obtained pics and videos of the four-time champion hitting up "Great America" in Santa Clara ... just two days after the 34-year-old was seen partying his ass off at the Warriors' championship parade on Monday.
Witnesses tell us ... Curry -- flanked by his three kids, Riley, Ryan, and Canon -- was all smiles throughout the day.
