A Galveston day trip from Houston
About 50 miles down I-45 — 45 to 60 minutes in normal traffic. Here's the drive, where to park, and a 6-hour plan that fits between the morning and evening rush.
The drive
~50 miles · 45–60 min
Straight down I-45 South from downtown Houston across the causeway. It's the only road onto the island and the hurricane evacuation route, so traffic can double the trip — leave by 9 AM, head back before 5 or after 7.
Where to park
Seawall · $2/hr
Free on the Seawall's north side (12th–19th, 33rd–39th, 53rd–61st, 85th–91st); otherwise $2/hr, $16/day max, metered 10 AM–6 PM daily. Downtown meters run 9 AM–6 PM Mon–Sat, free Sundays. Pay by plate with PayByPhone.
Nine to five, roughly
The 6-hour plan
Park once, stay on foot and the trolley, and you'll fit the beach, a Gulf lunch, and the Strand before the drive home. Each stop opens the page with the real detail.
Late morning
Park once, then walk the Seawall
Leave Houston by 9 and you clear I-45 before the beach crowd. Park along the Seawall (free north-side stretches, or $2/hr paid) and start with the Gulf on your right.
Pick a beach →Midday
Feet in the Gulf, or ride the trolley
Swim or walk the sand, then skip moving the car — the island trolley loops the Seawall and downtown for a dollar. Check today's beach verdict before you commit.
Today's beach call →Early afternoon
Lunch on the water
Gulf seafood is the whole point. Start with the vetted picks rather than the first sign you see off the Seawall.
Where to eat →Mid afternoon
The Strand + downtown
Trade the beach for the 19th-century downtown: brick storefronts, galleries, and the free historic-marker walk. It is a short trolley hop or drive from the Seawall.
Things to do →Before you go
Beat the I-45 return
Roll out by 5 or linger past 7 — the evening rush back to Houston can double the drive. A sunset walk buys you the gap.
