To view the thrombolites it's just 600 m stroll over the walkboard, it's not necessary (and not worth it) doing the 5km. You can just go to the giant and come back (3,5 km return).

Sehr schöne Entwicklung über den Tromboliten. Wir gingen 5 km auf dem Weg, der angegeben wurde.

Sehr guter Spot.

But really too many mosquitoes to go out to take the picture ..
