If you haven't been up the new Sea to Sky Gondola then I strongly suggest you check it out. The views are amazing!
You can do it two ways: round trip or hike up and down-load. Personally I recommend hiking up. It will take you about 3 hours depending how often you stop and your fitness level. The trail leaves from the Sea to Sky parking lot and connects with the chief trail. It then back cuts to form the new Lower Sea to Summit trail. Further up the mountain the trail splits to form the Upper Sea to Summit trail and the Wrinkle Rock trail.
If you are looking for a more adventurous hike take the Wrinkle Rock trail. It's a little bit shorter than the Upper Sea to Summit but has a steeper grade. The Wrinkle Rock trail also zig zags under the gondola and has ropes similar to those on the Chief for you to hike a rock face.
The Upper Sea to Summit trail is gentler than the Wrinkle Rock but will take a little longer. The trail is lined with young alders curling and reaching for the sunlight. The result is a whimsical trail curling through the mountainside.
Once you're at the top, whether you chose to hike or take the gondola, make sure you leave yourself time to walk the Panorama trail. It has several view points of the surrounding area but the best is the Chief view point!
