coastal oregon is amazing, so definitely go that way if you have the time
I have heard good things about the redwoods in north california...not sure where those are
definitely check out science world in vancouver. sooooo much fun
i suggest 4th avenue (ski/board shops) granville st. and robson street, and main st. (hipster alert) in vancouver if you wanna go shopping
if you're into photography and hiking try stanley park, ubc, grouse mountain/the grouse grind, mount seymour, cypress mountain, lynn valley/capilano suspension bridge
if you're into skimboarding try wreck beach and spanish banks
if you're into skateboarding try the seylynn hall bowl (legendary) near phibbs exch. in north van, the metrotown park in burnaby, hastings skatepark in east van (at the PNE - hastings st. and renfrew), and check out PD's hot shop on 4th avenue near macdonald st.
pot block is around hastings and cambie.
