We will be visiting GNP in 2013 from June 21-30 with 16 people ranging in ages from 3-65. I have a couple of questions. 1. We are renting a house in West Glacier but want to explore a many different areas of the park as possible. I have read that the earliest the GTTSR will open is June 21 due to the construction schedule. Is it likely that it will be fully open while we are there? 2. Also, we are planning on doing the Grinnell Glacier and Iceberg Lake hikes while we are there but again, these are on the east side and weather dependent. What are recommendations for must-do hikes on the west side in case GTTSR doesn't open as I am hoping? 3. Any other suggestions? We will be booking a boat ride as well as a horseback/wagon combo while we are there. Love day hikes and things we can do as a large group. Thanks for any advice!
