Two roads, both connect to Port Moody, East Rd. and Sunnyside Rd. (which connects to Ioco) East Rd. is connected to Forest Parkway in Port Moody. East Rd. in quite tough shape as the road bed has collapsed, constant patching hasn't done much to help. Beware of potholes, and driveways in blind rises, corners etc. There is not unlimited parking in Buntzen Lake and often on sunny weekends the lake will be full from 11/12 until about 5 in the afternoon, there is no street parking on nearby streets, however sometimes residents who live close to the lake will allow people to pay to park on their lawns or dirt or driveway. Do not attempt to park in the nearby trailer park, first there is nowhere to do it, second you'll probably be towed. If your car is towed it will be towed by Coquitlam Towing, so it will be in the impound lot. They have several so give them a call at (1) 604 939 6474 (note the 1 is not necessary when phoning from the vancouver locale)
C26 shuttle bus runs from Anmore through to Port Moody station, you can get a listing of times and stops etc at http://www.translink.bc.ca/Transportation_Services/default.asp The C26 stops nearby the lake. otherwise private vehicle, or you could phone a taxi, but it would be rare to hail a cab in Anmore. Be warned the gates close at 9 during the summer and often much earlier during the winter. If your car is in and the gates are closed your stuck until tomorrow, noone will open the gates for you. If you are very lucky a resident of Buntzen Bay may come by, (they have keys to some of the gates) and let you out but don't count on it. Instead of waiting for a buntzen bay resident to come by your better off trying to use a cell phone (which probably won't work) or the pay phone to phone for a taxi or a buddy to pick you up.
Buntzen Lake Regional Park, has a swimming beach and some great day hikes, ranging from 45 mins Buntzen Lake trail to the Dilly Dally loop which is a 10-12 hour hike. There are often map brochures in the park by the large map signs.
Hikes, swim, BBQ, fish (you need a freshwater liscense, which are available at the corner store on the road in) enjoy the outdoors at Buntzen lake. Only boats with small electric engines (check the specs before bringing a powered boat) are permitted on the lake (BC Hydro excepted) otherwise you can canoe, or kayak. You can rent a canoe from the Corner Store on the way to Buntzen Lake. The lake used by BC hydro for power generation at the Buntzen Lake Dam. There are a few buildings around the lake, a couple of abandoned houses towards the north end, one which was built for a movie. Otherwise buildings are property of BC hydro and should not be entered. Although Buntzen lake is used for power generation you can swim in it, there will be a large strip of logs signalling where you can not swim/boat past on the north side. There are three bridges across the lake, the floating bridge at the extreme southern end, the suspension bridge more or less in the middle and the Hydro service road at the end of the lake.
There is a concession with some fast food (burgers etc) otherwise plan on bringing all that you're going to eat.
Anmore Camplands, otherwise there is a B&B somewhere by Thompson and East Rd. Otherwise head to Port Moody.
