If you cycle around the Hallwilersee, you can take a break at the Tennwill beach to refresh yourself in the water of the lake on hot summer days. On the large lawn you can relax comfortably or tan on the sundeck. Action is provided by the volleyball court and table tennis tables. If you have your own food with you, you can also barbecue.
The lido is open daily from April to September. In the low season from 9 to 19 o'clock and in the high season from 8 to 22 o'clock. Admission costs 5.50 CHF for adults and 2.50 CHF for children.
