With a stay at Sydney Beachouse YHA - Backpacker in Sydney (Collaroy), you'll be a 2-minute drive from Dee Why Beach and 6 minutes from Long Reef Point Lookout. This hostel is 3.1 mi (4.9 km) from Mona Vale Beach and 4.9 mi (7.8 km) from Manly Beach.
Pleasant stay, met my needs re location. Very few rooms occupied, clearly a quiet time, very little visible staff presence. The staff were friendly and helpful. The place is looking tired and will soon need refurb.
