From downtown Bariloche:

Bus: The company Via Bariloche that heads to El Bolsón, get off at the Park Rangers Office “Mascardi”, where is the paid entrance to the National Park From here walk another 500 mts. to the trailhead. Bus ticket can be purchased at the Bus Terminal or Via Bariloche office on Mitre 321.

By car: Take route 40 towards el Bolson, after 36 km. there is the turn off right just after Villa Mascardi. Along a gravel road very shortly is the paid entrance to the National Park at the Mascardi Rangers Office. From here walk another 500 mts. to the trailhead.

–

The trail starts on the left hand side, some 500 mts. after the Mascardi park entrance on the way to Pampa Linda. Leave the car at the park entrance and walk from there as there is no parking available close to the trailhead.

The start of the trail is pretty steep and quite a lot of elevation gain. Then it levels out all the way to the lagoon. At the beginning of the season the marsh lands are very wet so have an extra pair of shoes and look for stepping stones and branches to walk along.

There isn’t a trail that goes completely around the lagoon, you can walk along one shore, then to the next going past the entrance spot.

Follow the same trail back down to the road.
