The Environmental Management Authority (EMA) and the EMA Youth Ambassadors will hold its first eco-concert, “OMG! — Orient My Generation,” which will be held tomorrow at Queen’s Hall from 6 pm to 8 pm.

Caribbean Hiking Adventures leads the way this Sunday to Lemond River. This hike begins with a scenic forest walk up the gentle inclines of the Yarra Forest, then heads downhill to the river base. Hikers then navigate several gorges — a river exploration like no other – until they return to La Fillette.
