A summer-season water play pad sits near the playground at Lakeview Park on Discovery Lake, where families can also fish from a dock and walk the flat paved loop trail around the water. Free parking, picnic benches and bathrooms are on site.
When to go. Peak summer highs in San Marcos average 82°F — warm enough for a splash pad through most of the season without being punishing at midday.
