Swimming at Playa Punta Cascajo is challenging and generally not recommended. Its location near the ría mouth means it experiences stronger currents and more wave action than inner-ría beaches. The pebble beach composition and cold Patagonian water temperatures (typically 8-14°C year-round) make swimming uncomfortable for most visitors. The beach is more suitable for walking, beachcombing, and coastal exploration. Families can enjoy the shoreline and tide pools, but should supervise children closely near the water. The natural coastal environment offers scenic beauty without requiring water entry to appreciate its character.

Playa Punta Cascajo can be visited throughout the year, with the experience varying by season. Summer months (December-February) offer the most comfortable air temperatures, typically 10-20°C, ideal for beach walks and exploration. Spring and autumn provide excellent conditions for photography and wildlife observation with fewer visitors. The exposed location near the ría mouth means wind can be significant any time of year—bring appropriate layers. Winter visits require warm, wind-resistant clothing but reward visitors with dramatic seascapes and solitude. Less crowded conditions prevail year-round due to the remote Patagonian location.
