A group of friends and I did Hallett Peak on June 28th and other than the snowfield that is usually there most of the year by hitching post, the trail was snow free. Good times. We also climbed Timberline Falls which also was snow free except for a stretch of 20-30 feet around the Loch. The falls are very wet and slippery. We made it to the top and then it started to rain so we did not get to Sky Pond but we made last year so it was an easy decision to turn around. Twin sisters and Deer Mt. were both snow free. A very nice week in Estes with mostly sun and low 80s for the first part of the week and then upper 60's with some afternoon rain the last part of the week.
We plan on doing Mt. Ida for the first time next year.
Sounds like you picked some good hikes for this time of year. Glad to hear snow free trails.
