Call Burrard Water Taxi they will transport you and your bikes to the head of Indian Arm
Yup, they will.
Knnn, try this one on for size, me and a few buds did the ride a few years back incorperating kayaks rented from Deep Cove. We did it a couple times while training for sea to summit adventure races.
4 guys rented two double kayaks and 4 others drove up to Squamish with bikes and parked at the bottom of 9 mile hill where the Indian river FSR begins. You want to get about a 1 to 2 hr head start on the ride.
So the riders ride up and over to the top of Indian Arm and the paddlers paddle up. Meet at the top and swap kayaks for bikes(Remember the car keys too!) Its a really fun day or there's a few camping spots right where the Indian River lets out if you want to turn it into a weekender. Then at the end each group drives back in the other's car.
A couple tips though,
Have the stronger climbers ride out of Squamish as the climb is steeper in that direction.
Don't try it till at least July this year because with the snow pack that FSR probably won't be passable till middle summer.
Indian Arm gets a nasty wind and pretty choppy between 2 and 5 pm on alot of summer days for some reason.
PS: If you like this option let me know I'd probably jump on board for the trip.
