A clean side stream forms this series of seven waterfalls and pretty emerald-green pools known as Los Siete Altares (Seven Altars, $1.50 admission) lying five kilometers northwest of town.
Robberies have been reported here in the past, so it’s safest to go as part of a group. Any of the recommended guide companies can get you there, though Exotic Travel runs an adventurous option on mountain bikes.
The river falls can be reached by walking along the shore northwest of Playa Quehueche for a few kilometers and then wading across a side stream before turning left onto a path leading to the first of the falls. The seventh waterfall and pool is the nicest. You’ll have to clamber up the slippery rocks to get there, but it’s worth it.
