Grab a waterproof bag and jump in at Eichholz; floating down to Marzili is the only way to experience Bern in summer. The glacial water is freezing but the current does all the work while you drift past Parliament. Skip the crowded public pools and stick to the river banks for a beer instead. Give yourself two hours for a full loop. If you need historical context while drying off, an audio-guided walking tour fills the gaps.
